AURORA OUTLOOK: High latitude sky watchers should be alert for auroras on May 11th. That's when a disturbance in the solar wind (a "co-rotating interaction region") is expected to move past our planet and possibly disturb polar magnetic fields. NOAA forecasters estimate a 30% chance of geomagnetic activity.

AMAZING ERUPTIONS: This weekend, magnetic fields around sunspot 1069 became unstable and erupted--over and over again. On May 8th alone, the active region produced more than half a dozen flares. NASA's Solar Dynamics Observatory (SDO) video-recorded each of the explosions with a clarity ten times better than HDTV. Click on the image to view a sample "first look" movie:

http://www.spaceweather.com/swpod2010/09may10/cflare_aia_304a_2020ut_movie.mpeg?PHPSESSID=ujleqv97r4f6nb08n5vhjgjee4

On the Richter scale of solar flares, the eruption you just witnessed registered C2.4. In years past, solar physicists regarded C-flares as minor events, but SDO is revealing them to be quite spectacular. Plasma plumes accelerating out of the blast site are filled with magnetized gas hotter than 80,000 K and are big enough to swallow Earth itself. Earth was not, however, in the line of fire, so we will feel no geomagnetic effects from these events.

Here are three more highlights from May 8th: C1.8-flare, C9-flare, B7-flare. These were selected from the Lockheed Martin Solar and Astrophysics Laboratory's excellent latest events web site.

Instigating sunspot 1069 has rotated over the sun's western horizon, out of sight of Earth and SDO, so the show is over for now. It probably won't be long, however, before SDO turns another "minor" eruption into a jaw-dropping spectacle. Stay tuned.

BONUS: SDO also observed a pair of impressive eruptions on May 5th: This one:
http://www.lmsal.com/solarsoft/gev_20100505_1611/ssw_cutout_20100505_154002_aia_193_S26W17_20100505_154000_m.mpg
sent a "solar tsunami" rippling through the sun's atmosphere and this one propelled a massive magnetic filament off the sun's southwestern limb.

IONOSPHERIC DISTURBANCE: On May 5th, a pair of solar flares bathed Earth's upper atmosphere in X-rays and caused a double-wave of ionization to sweep over the Americas. This improved the propagation of low-frequency radio signals, which use the ionosphere as a reflector to skip over the horizon. Rogerio Marcon of Campinas SP Brasil was monitoring a 24 kHz aviation beacon when the flares occurred, and he recorded a double-surge in the beacon's signal strength:

User Image
Each of the spikes is called a "SID," short for sudden ionospheric disturbance. One was produced by a C9-class flare at 11:52 UT; the other by a slightly stronger M1-class flare at 17:19 UT. The two SIDs ride atop a slower undulation in radio signals caused by the daily rising and setting of the sun. In terms of radio propagation, the two flares were as significant as the sunrise itself!

With solar activity on the rise, sudden ionospheric disturbances will become more common. Interested?


Up coming news:
Voyager 2 which hit that termination shock last year and posibly found the shockwave that may reach us on 2012 (check earlier pages for this news) seems to be DAMAGED and is now not transmitting any data other than its self. Bummer..

Also water in space is electrified. No one knows why, and will I post about Phobos and NASA's mission there? Maybe..

First up:

Relativity To Be Tested With Three Spaceships and Lasers

http://gizmodo.com/5535208/relativity-to-be-tested-with-three-spaceships-and-lasers

User Image
Quote:
55 years after Albert Einstein's death, physicists will be testing something he scribed in his theory of general relativity report. Three spacecraft flying 3million miles apart will fire lasers at each other, overseen by Nasa and the European Space Agency.

It sounds bonkers (and like a terrible waste of money), but once and for all we'll discover if gravitational waves are actually possible. The laser beams won't harm the spacecraft, which will be carrying floating cubes of gold platinum, instead they'll be used to measure the changes. It's said to be the largest scientific apparatus to ever be built�and sounds like one of the more expensive, too.

A Glasgow University professor by the name of Jim Hough told The Telegraph that gravitational waves "are produced when massive objects like black holes or collapsed stars accelerate through space, perhaps because they being pulled towards another object with greater gravitational pull like a massive black hole."

It's apparently the last part of Einstein's theory of general relativity to be tested, but hasn't been possible yet due to the tricky nature of detecting them. Why bother with all this time and expense? Apparently once we learn more about gravitational waves, we learn more about space and the universe around us�giving us insight into collapsed stars' matter and black holes.

Unfortunately we've got a good number of years ahead of us before the Laser Interferometer Space Antenna (or LISA as it's known) is able to proceed, with 2020 being the year we unlock the last piece of Einstein's puzzle

Amazing find:
NASA Studies Find Omega-3 May Help Reduce Bone Loss
http://www.nasa.gov/home/hqnews/2010/may/HQ_10-108_Omega-3_Studies.html

That's right, NASA figured out how to treat osteoporosis. That is because bone loss happens while in space. As I've said before, we really have to fund NASA more. As I wrote on page 12, so many things we all use every day is thanks to nasa. No other government agency that has ever been created that pays back more than what it cost in funding! NASA is a money making gold mine for the economy.


Ok, well maybe not this next story BUT! It is kinda cool.

The Crazy Ride of Orion's Launch Abort System On Video

Watch the video of the completely successful�and awesome�Orion Launch Abort System test. Hey NASA, in the future, please give me a call. I'll sign any papers you want, but I must get inside for the next ride.

The 97-second full test of Orion's Launch Abort System�which was already budgeted before Obama's space plan�was conducted on May 6. At 9AM EDT, the abort motor accelerated the Orion crew vehicle with half-million pounds of thrust for six seconds. In the first three seconds, the crew module reached 445mph. Three seconds later, it was flying at 539mph, 1.2 miles above the U.S. Army's White Sands Missile Range near Las Cruces, the largest military installation in the United States at 3,200 square miles (8,300 square kilometers).

At that time, the attitude control engine kicked in, reorienting the craft using eight thrusters with 7,000 pounds of thrust. When the angle was correct, the jettison motor ejected the launch abort system, leaving the crew module clear for parachute deployment. A few seconds later, the spacecraft touched ground at 24 feet per second.
User Image

NASA can always use that system in future projects so it isn't a total waste of money. And it would have had to have been tested at some point in time anyway. FIRE AWAY!

Here's another:

Nifty way to get funding by getting tourists up there.



Now for something that doesn't seem real -imagine that, in this thread
NASA and GM are making Droids.
Whats that? The federal government making droids?
User Image
Meet (such an original name) R2
User Image
I have to do this..
User Image
(Interesting choice of pose by NASA)

R2 stands for Robonaught 2. He will be sent into space in the NEXT MONTH for testing on board the ISS! shocked
Here is a video first:

R2 will be used like an Avatar (like the movie but not alive) people on the ground (high paid teenagers who are no doubt awesome at video games) will be using computers/controllers/body simulators and the signals will be sent from Earth to space by remote and activate the R2s in the space station or on THE MOON. Amazing. R2 can hold tools, can weld, can build things, use screw drivers, drills, riveters, really just about anything you can DO in space R2 will do it better with out the need of the bulky space suit. Speaking of which, R2 has interchangeable parts. Each of his arms can be removed and new job specific arms can be attached. Need to hold a drill for a whole day, (or more) just replace the humanoid arm with a drill arm. Easy, Don't need to walk on the moon? Too slow? Change the lower torso and legs to really get rolling.. I mean, really.
User Image

By now I would guess you've seen the big GM on the front of R2... perhaps this might have had to something to do with the bail out last year...

But hey, not to worry, this droid will help us! It can build space stations and cars, go to the moon and all sorts of other things... Wait if it can hold a drill.. it could hold a gun.. nah that is crazy talk... but wait..



In the earlier videos it shows R2 was made by DARPA. shocked... The DEFENSE DEPARTMENT! Well.. I'll keep an eye on that.. I think we all know several scenarios that that sort of thing could lead too..
User Image

Odd and expensive thing:
This suit is made of gold.. and lots of it. Reasons are pretty much the same reasons we add gold to just about any satellite/shielding (space helmet visors are coated in gold) to reflect radiation from the sun back and keep from damaging the host body. Also gold is an awesome conductor which I'm guessing this thing being made of lots of gold means solar flares won't damage it while bobbing abouts in space and keep it from frying.

Next up: Voyager 2

Voyager 2 in serious distress:
User Image
Quote:
Engineers have shifted NASA's Voyager 2 spacecraft into a mode that transmits only spacecraft health and status data while they diagnose an unexpected change in the pattern of returning data. Preliminary engineering data received on May 1 show the spacecraft is basically healthy, and that the source of the issue is the flight data system, which is responsible for formatting the data to send back to Earth. The change in the data return pattern has prevented mission managers from decoding science data.

The first changes in the return of data packets from Voyager 2, which is near the edge of our solar system, appeared on April 22. Mission team members have been working to troubleshoot and resume the regular flow of science data. Because of a planned roll maneuver and moratorium on sending commands, engineers got their first chance to send commands to the spacecraft on April 30. It takes nearly 13 hours for signals to reach the spacecraft and nearly 13 hours for signals to come down to NASA's Deep Space Network on Earth.

Voyager 2 launched on August 20, 1977, about two weeks before its twin spacecraft, Voyager 1. The two spacecraft are the most distant human-made objects, out at the edge of the heliosphere, the bubble the sun creates around the solar system. Mission managers expect Voyager 1 to leave our solar system and enter interstellar space in the next five years or so, with Voyager 2 on track to enter interstellar space shortly afterward. Voyager 1 is in good health and performing normally.

"Voyager 2's initial mission was a four-year journey to Saturn, but it is still returning data 33 years later," said Ed Stone, Voyager project scientist at the California Institute of Technology in Pasadena. "It has already given us remarkable views of Uranus and Neptune, planets we had never seen close-up before. We will know soon what it will take for it to continue its epic journey of discovery."

The original goals for the two Voyager spacecraft were to explore Jupiter and Saturn.

As part of a mission extension, Voyager 2 also flew by Uranus in 1986 and Neptune in 1989, taking advantage of a once-in-176-year alignment to take a grand tour of the outer planets. Among its many findings, Voyager 2 discovered Neptune's Great Dark Spot and 450-meter-per-second (1,000-mph) winds. It also detected geysers erupting from the pinkish-hued nitrogen ice that forms the polar cap of Neptune's moon Triton. Working in concert with Voyager 1, it also helped discover actively erupting volcanoes on Jupiter's moon Io, and waves and kinks in Saturn's icy rings from the tugs of nearby moons.

Voyager 2 is about 13.8 billion kilometers, or 8.6 billion miles, from Earth. Voyager 1 is about 16.9 billion kilometers (10.5 billion miles) away from Earth.

The Voyagers were built by JPL, which continues to operate both spacecraft. Caltech manages JPL for NASA.

For more information about the Voyagers, visit: http://voyager.jpl.nasa.gov/.


My take on it:
Ok, grab your tin foil hat, remember back on page 10 of this thread (little from the top) Heck I'll just quote my self:

This might be a problem... (this is double posted in this thread and the 2012 thread)

GIANT RIBBON DISCOVERED AT THE EDGE OF THE SOLAR SYSTEM:

For years, researchers have known that the solar system is surrounded by a vast bubble of magnetism. Called the "heliosphere," it springs from the sun and extends far beyond the orbit of Pluto, providing a first line of defense against cosmic rays and interstellar clouds that try to enter our local space. Although the heliosphere is huge and literally fills the sky, it emits no light and no one has actually seen it. Until now.

NASA's IBEX (Interstellar Boundary Explorer) spacecraft has made the first all-sky map of the heliosphere and the results have taken researchers by surprise. The map is bisected by a bright, winding ribbon of unknown origin:

User Image

"This is a shocking new result," says IBEX principal investigator Dave McComas of the Southwest Research Institute. "We had no idea this ribbon existed--or what has created it. Our previous ideas about the outer heliosphere are going to have to be revised."

The two Voyager spacecraft (labeled V1 and V2 in the figure) have spent decades traveling to the edge of the solar system for in situ inspection of whatever might be there--but ironically both spacecraft missed the ribbon. "It's like having two weather stations, but missing the big storm that runs between them," says Eric Christian, IBEX deputy mission scientist at NASA's Goddard Space Flight Center.

At the moment, theorists are "working like crazy" to understand this discovery and how the ribbon might effect the ability of the heliosphere to shield us from cosmic rays. Science@NASA has the full story
http://science.nasa.gov/headlines/y2009/15oct_ibex.htm


What the Heliopause looks like. It is what exists just out side our solar system. Galactic hardcore winds. Nothing could probably survive out there. No star could form, no planet could stay together and no probe could survive.
http://www.nasa.gov/mpg/392292main_JourneyToHeliopauseVis1.mpg

Our Sun (as with all stars) keeps the galactic wind from entering the solar system. That is what keeps us safe here. Lets us send probes to other planets and moons and test the limits of our solar system. The area that exists between instant death wind and our own solar system is called the Heliopause. However.. If this wind was to ever enter our solar system... it would spell doom to every planet for thousands of years. It would instantly remove any atmosphere of any planet or moon and vaporize any organic material it comes in contact with.

What this ribbon could mean is... well.. This is just my take on it. This seems very coincidental all this hoopla over 2012 and end times. All while in 2012 we are set to align to the galactic center of the Milky Way. No one knows what would happen if the Earth were to align with it. Whats out there? Energy? Gravity? Would it effect life? No one knows. Odd how this ribbon of energy popped up in the exact spot where our solar system is entering this galactic center line. (Think of a small ball bobbing up and down around a CD or record. The area where the ball lines up with the side of the CD or record would be the galactic center) We do this every 22 thousand years.... Anyone know anyone from 22 thousand years ago? That's kinda what is scary in this story.

Got me now? Good, watch the rest of the videos now.

Ok, so back Oct 16th, 2009 (officially) we get word that Voyager has incountered some serious doo-doo and found a huge energy ribbon in space. This ribbon matches perfectly with the center line of the galaxy (see 2012 thread) NASA says "whoa now, take off the tin foil hat. There is a perfectly reasonable explanation of this ribbon but it will take about 6 months to test the theory"

This theory is roughly as follows:
The energy ribbon isn't actually there, our solar system is surrounded by a bubble. This bubble is called our helosphere and it is made by the Sun. Energy from the Sun pushes back deep space radiation and keeps the solar system safe, think of the bow of a ship pushing through water. Our Sun keeps our solar system protected from this radiation as we go sailing through the Milky Way much like the bow of a ship. At the point of impact where it cuts through the water there will be ripples as the water breaks around the front of the ship. The theory is the energy ribbon is actually a reflection of our own Suns energy. Sort of like looking up from the bottom of a pond and you see the surface of the water but it looks like a mirror and you see another person (you) looking back down at you from above you. This roughly sums up the theory. NASA said it would take several months to compile the data from the Suns activity. If the Sun has a strong eruption and the energy ribbon grows or moves, we know it is a reflection!

Now, several things about that theory doesn't (pardon the pun) hold water. 1) The energy ribbon matches perfectly with the center of the galaxy.
http://www.nasa.gov/mpg/392978main_RosineGalaxyZoom512x288.mpg
2) The ribbon is exactly where the helopause (point where the front of the ship cuts through the water) is! 3)... Using the same analogy, what happens when the front of the ship has a hole? Water gets in...

That is my point! Voyager 2 was suppose to tell us "all is well! it is a reflection! Its ok!" Instead we get the news that Voyager 2 is about to be destroyed by the heloshock..

Cover up or convenient coincidence?

Wow, I'm surprised government/nasa officals didn't come club Spiff over the back of the head, blind-fold him, throw him in the back seat and take him to R2s control room and use him as their slave!

Ok, ok, all joking aside this is one amazing invention. Gold is the best conductor for space travel conditions so it would make since that he would be made primarily of the precious metal.

Based on all his testing, and facts put out there for us to see, the 1st question that comes to mind is, "How long will he last out there"?

I really would like to know if they have gave an estimate on how long they expect him to survive and function properly.

I wonder if there will be pictures presented to us earthlings about our wonderful little R2 making a difference somewhere out there? Wouldn't it be amazing if one of our satellites could show us him working in real time?!

I guess its up to the ones in charge to decide. We can only keep our fingers crossed that our tax payer dollars wont go to waste and that R2 will accomplish what he set out to do and more so.

INCREDIBLE SKY SHOW: Space shuttle Atlantis is about to leave Earth on its final voyage to the ISS. An on-time launch from Kennedy Space Center today at 2:20 pm EDT would set the stage for an incredible sky show this weekend. On Saturday and Sunday evenings, many observers will be able to see the ISS and Atlantis flying past Venus and the crescent Moon. Get the full story from Science@NASA.

Past weeks Sun News:
BIG TWISTER: On May 1st, a magnetic filament on the sun wound itself into a twist and erupted. NASA's STEREO Ahead spacecraft was in the perfect position to observe the blast. Click on the image to set the scene in motion:
http://sohowww.nascom.nasa.gov/pickoftheweek/May_promerupt_zm_best.mov
The time-lapse movie spans three days, April 30th to May 2nd, and shows not only the big twister, but also many smaller filaments that twist and swirl without erupting. Such activity occurs every day and is part of the dynamism of the ever-changing sun.




PARTING SHOT: The "Mother's Day Flare Show" came to an end on May 9th when active sunspot 1069 rotated over the sun's western horizon. But wait--there's more to see. Even after the sunspot departed, it continued to hurl material up and over the limb. Click on the arrow to view a parting shot:
http://www.lmsal.com/solarsoft/gev_20100509_2048/ssw_cutout_20100509_204806_aia_171_N40W86_20100509_204805_m.mpg

NASA's Solar Dynamics Observatory recorded the eruption using the Atmospheric Imaging Assembly (AIA), a bank of telescopes that views the sun at multiple extreme ultraviolet wavelengths. The AIA's 171 filter (false-color blue) traces magnetized gas with temperatures around a million degrees K. This means the eruption you just witnessed was hot.

SPACESHIPS IN THE SUN: Last Sunday, May 16th, in the blue skies of Spain, a pair of tiny shadows flitted across the sun. Astrophotographer Theirry Legault and his telescope were in the countryside outside Madrid, and this is what they saw:


User Image
Quote:
"It was a solar transit of space shuttle Atlantis and the ISS," says Legault, who traveled from France to witness the event. "The time was 13:28 UT, about 50 minutes before docking. Atlantis had just begun the 'R-bar pitch maneuver'--a backflip that exposes the shuttle's heat-shield to the crew of the ISS for inspection."

Because of the high orbital velocity of the ISS, its occasional transits of the sun last no more than a split-second (0.54s in this case) and require considerable skill to catch. "I stationed myself near a small town named Saelices in a quiet area with nobody around," says Legault. "I prefer to be alone because I need the concentration!"


NASA's shuttle program is coming to an end later this year, and Atlantis is making her final scheduled voyage. For this reason, the STS-132 mission patch shows Atlantis heading into the sunset.
User Image

There is, however, a possibility that Atlantis might fly again. If so, make that sunset a solar transit.

Will Atlantis fly one more time?
http://spaceflightnow.com/shuttle/sts132/100512sts135/

SOLAR FILAMENT: The sun may be spotless today, but it certainly is not blank. A long dark magnetic filament is looping around the northeastern limb, stretching almost 100,000 km from end to end:
User Image

Long, bushy filaments like this have been known to grow unstable and erupt, producing a type of spotless flare called a "Hyder flare." If that happens now, Earth would likely feel some effects from the blast because the filament is turning to face our planet. Readers with solar telescopes are encouraged to monitor developments.

Holy cow, I'm a slacker. So here is the space news for the past 2 weeks.

Overview: The sun is ticked again, Jupiter is changing and some Mars news.

first up:
Jupiter. Last month Jupiter lost one of its red stripes along the equator. This seemed odd enough then it lost a second red stripe, turning the middle of the planet WHITE. This obviously let Jupiter reflect more light back than normal and it became a bit brighter. (So if you saw something brighter in the eastern sky in the past few weeks, its probably Jupiter.) So here is what Jupiter looks like now:
User Image
*note, it has further lost another stripe after this picture, currently looking for another shot*

http://www.dailymail.co.uk/sciencetech/article-1277734/Jupiter-loses-stripes-scientists-idea-why.html

User Image
The rings keep disappearing and reappearing, scientists have NO IDEA why this is going on. Just thought I would throw this out there though, Jupiter is only 1 element off from our Sun... and it is possible for Jupiter one day to ignite into a star. I'm just saying... So all this is pretty weird about Jupiter, thats gotta be about it.... right? Wrong!

Impact today:
JUPITER IMPACT! Amateur astronomers Anthony Wesley of Australia and Christopher Go of the Philippines have independently observed an impact event on Jupiter. The strike occurred at 20:31 UT on June 3rd and produced a bright flash of light in the giant planet's cloudtops:

User Image
Video http://www.spaceweather.com/swpod201...iterimpact.wmv

http://www.spaceweather.com/
"I still can't believe that I caught a live impact on Jupiter," says Go, who has made a must-see video of the event.

"There were no visible remains at the impact point for the next half hour or so, until sunrise put an end to the imaging," says Wesley.

The nature of the impactor is presently unknown. It might have been an asteroid or a comet. In either case, a dark and cindery debris field is expected to develop around the impact point; that's what has happened in the aftermath of previous Jupiter impacts. Professional and amateur astronomers are encouraged to monitor Jupiter in the hours ahead, and stay tuned for updates.

Update: Anthony Wesley has pinpointed the impact site at Jovian latitude minus 16.1o, and central meridian longitudes CM1: 300o, CM2: 33.8o and CM3: 210.4o.

This SDO close-up of a filament and active region, taken in extreme UV light, shows a dark and elongated filament hovering above the Suns surface (May 18, 2010). The bright regions beneath it, which show where heating is going on in the magnetic field, send up shafts of plasma that trace magnetic field lines emerging from them. Filaments are cooler clouds of gas that are suspended by tenuous magnetic fields. They are often unstable and commonly erupt. This one is estimated to be at least 60 Earth diameters long (about 500,000 miles).

FAST-GROWING SUNSPOT: Sunspot 1076 has tripled in size since yesterday and now poses a growing threat for C-class solar flares. Cai-Uso Wohler sends this picture of the active region from Bispingen, Germany:

Each of the dark cores in Wohler's image is about the size of Earth. That's why the active region is such an easy target for backyard solar telescopes. Monitoring is encouraged.

It was an asteroid:

Quote:
Most importantly, they found no "halo" around the latest collision site. A comet would have generated a halo of fine dust as it impacted the surface.

The clues helped them to conclude that the mystery object was probably not a dusty comet but a solid space rock that perhaps came from a nearby asteroid belt.

Agustin Sanchez-Lavega of the University of the Basque Country in Bilbao, Spain called Jupiter a "natural laboratory" to see what might happen to our planet in the event of a similar collision.

"It would be a catastrophe," he said.

"The Jupiter impact produced a pattern of debris some 5,000km long and 2,800 km wide - half the size of the Earth. And even if the response of the Earth atmosphere is different from that of Jupiter, entire continents could be destroyed."
Amateur astronomers

The scientist also commented on the latest flash spotted on Jupiter by Anthony Wesley and another amateur, Christopher Go from the Philippines.

It is believed to be the very first image of a meteoroid hitting a planet.

This also shows that amateur astronomers now have the necessary high quality technology to capture such events that only last a few seconds.

"We cannot devote the Hubble space telescope or other telescopes to observe Jupiter regularly, it is impossible," he said.

"And the amateurs make a very good survey of what is happening there, contributing to our database."


Yikes!







The Sun:
CORONAL HOLE: NASA's Solar Dynamics Observatory is monitoring a dark rift in the sun's atmosphere. The spacecraft's Atmospheric Imaging Assembly (AIA) took this extreme ultraviolet picture just hours ago:
User Image
It's a "coronal hole," a vast region where the sun's magnetic field has opened up and allowed the solar wind to escape. Indeed, a solar wind stream flowing from this hole is heading toward Earth, due to arrive on June 7th or 8th. High latitude sky watchers should be alert for auroras on those dates.

Can You Count 400 Billion Stars In This Galaxy-Spanning Panorama?
http://gizmodo.com/5553428/400-billion-stars-in-a-800000+image-mosaic
Astronomers estimate that there are 200 to 400 billion stars in our galactic neighborhood, the Milky Way. I guess that someone tried to count them in this fully-zoomable, ultra-high-definition 800,000-image mosaic and got tired around 296,351,284,702.



The 800,000-image mosaic was assembled by NASA last year from Spitzer Space Telescope photographs. But looking at a 120-feet image is hard unless you are in front of a printed copy. That's why someone has put them all together into a fully-zoomable panorama that you can enjoy here.

About the above story about life on Titan. Yes! It seems legit! They picked up these elements of hydrocarbons in the atmosphere, then picked up the signature of methane and oxygen. Both were being monitored and every bit of each were accounted for. The signature of methane (which presumably is the by product of some beasty swarm flying in the clouds flew into the hydrocarbons and.... good bye hydrocarbons. Soon after the carbons disappeared EXTRA methane was picked up as the swarm moved away. What it looks like, some swarm of creatures (probably something like bacteria in clouds) flew into the hydrocarbons and ATE it all up. Expelled waste and flew away.

http://www.telegraph.co.uk/science/s...urns-moon.html
Quote:
Researchers at the space agency believe they have discovered vital clues that appeared to indicate that primitive aliens could be living on the planet.

Data from Nasa's Cassini probe has analysed the complex chemistry on the surface of Titan, which experts say is the only moon around the planet to have a dense atmosphere.

They have discovered that life forms have been breathing in the planets atmosphere and also feeding on its surfaces fuel.

Astronomers claim the moon is generally too cold to support even liquid water on its surface.

The research has been detailed in two separate studies.

The first paper, in the journal Icarus, shows that hydrogen gas flowing throughout the planets atmosphere disappeared at the surface. This suggested that alien forms could in fact breathe.

The second paper, in the Journal of Geophysical Research, concluded that there was lack of the chemical on the surface.

Scientists were then led to believe it had been possibly consumed by life.

Researchers had expected sunlight interacting with chemicals in the atmosphere to produce acetylene gas. But the Cassini probe did not detect any such gas.

Chris McKay, an astrobiologist at Nasa Ames Research Centre, at Moffett Field, California who led the research, said: We suggested hydrogen consumption because it's the obvious gas for life to consume on Titan, similar to the way we consume oxygen on Earth.

"If these signs do turn out to be a sign of life, it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth.

Professor John Zarnecki, of the Open University, added: We believe the chemistry is there for life to form. It just needs heat and warmth to kick-start the process.

In four billion years time, when the Sun swells into a red giant, it could be paradise on Titan.

They warned, however, that there could be other explanations for the findings.

But taken together, they two indicate two important conditions necessary for methane-based life to exist.

McNaught is baa~ck..

COMET McNAUGHT: A fresh comet is swinging through the inner solar system, and it is brightening rapidly as it approaches the sun. Presenting, Comet McNaught (C/2009 R1):




Michael Jger of Stixendorf, Austria, took the picture on June 6th using an 8-inch telescope. The comet's green atmosphere is larger than the planet Jupiter, while the long willowy ion tail stretches more than a million kilometers through space. These dimensions make the comet a fine target for backyard telescopes.

Comet McNaught can be found low in the northeastern sky before dawn gliding through the constellation Perseus. It is brightening as it approaches Earth for a 1.13 AU close encounter on June 15th and 16th. Currently, the comet is at the threshold of naked eye visibility (5th to 6th magnitude) and could become as bright as the stars of the Big Dipper (2nd magnitude) before the end of the month. Estimates are uncertain, however, because this comet is a newcomer to the inner solar system, and thus somewhat unpredictable. Readers are encouraged to wake up before dawn and monitor developments




BLUE STAR MEETS RED PLANET: There's a new "double star" in the evening sky. Bright blue Regulus is having a 1o close encounter with Mars. Look for the pair almost due west after sunset. Here, Tamas Ladanyi points them out from the shores of Fertő/Neusiedlersee Lake, a UNESCO World Heritage Area in Hungary:



"Both the planet and the star are about the same brightness, but the color contrast is absolutely wonderful," notes astrophotographer Pete Lawrence of Selsey UK. "An exquisite sight with the naked eye, binoculars or low power in a telescope - catch it while it lasts!"




Also since the announcement last week about this:
http://science.nasa.gov/science-news/science-at-nasa/2010/04jun_swef/
Every news website I have been to (and forum for that matter) has been talking about that. It is scaring the crap out of people! Get your suntan lotion, gonna be a hot couple of years.... got nothing to do with global warming though..

CRACKLING SUNSPOT: New sunspot 1078 is growing rapidly and crackling with low-level solar flares. Click on the image to view some of the action recorded on June 8th by NASA's Solar Dynamics Observatory (SDO):
http://www.spaceweather.com/swpod2010/09jun10/sizzle171.mpg
So far the relatively minor "crackles" shown in the SDO movie have had no effect on Earth. If the active region continues to grow, however, the flares could become more intense, leading to waves of ionization in Earth's upper atmosphere and disturbances in low-frequency radio propagation. Stay tuned.

FANTASTIC PROMINENCE: A long filament of magnetism circling the sun's north pole is rising into space, producing a truly fantastic prominence. NASA's Solar Dynamics Observatory took this picture just hours ago:

User Image

The extreme ultraviolet image shows a cloud of hot (60,000 K) plasma held suspended above the stellar surface by filamentary magnetic forces. The structure is five times taller than Earth and at least 20 times as long. These dimensions make it a fine target for backyard solar telescopes as well as advanced spacecraft.

If the filament becomes unstable and collapses (as magnetic filaments often do), plasma hitting the stellar surface could explode, resulting in a type of flare called a "Hyder flare."

Extra extra! The sun is TICKED! shocked

For the past 4 days now we have been looking at this... at least 5 times a DAY!

SOLAR FLARES: Today, June 12th at 0055 UT, new sunspot 1081 unleashed an impulsive M1-class solar flare. NASA's Solar Dynamics Observatory recorded the blast in high-resolution:

http://www.spaceweather.com/swpod2010/12jun10/mflare304.mpg

The explosion hurled a billion-ton coronal mass ejection (CME) off the sun's western limb; the cloud will probably not hit Earth. The explosion also produced a Type II radio burst. "Although the Sun was setting here in New Mexico, I was able to record the burst at 28 MHz and 24 MHz," says amateur radio astronomer Thomas Ashcraft. "Here is an audio file.
http://www.heliotown.com/Sr20100612_0054UTM2Ashcraft2824.mp3

The slow swoosh is radio noise from the sun!"

The M2-flare was followed at 0917 UT by an even more picturesque C6-flare. SDO recorded that one, too:
http://www.spaceweather.com/swpod2010/12jun10/cflare304.mpg?PHPSESSID=hf09ok47livibcbe1fflfb7bt1

movie, still frame.
User Image
More flares seem likely as restless sunspot 1081 continues to grow.

MAGNETIC UNREST: The magnetic field of sunspot 1078 is in a state of considerable unrest. Explosive reconnection events are happening every few minutes, resulting in a staccato rat-a-tat of low-level solar flares. The following movie from NASA's Solar Dynamics Observatory gives a one-hour sampling of the action:

http://www.spaceweather.com/swpod2010/11jun10/ar1078.mpg

Eventually, this growing sunspot could unleash a truly significant flare. Our planet, however, is not in the line of fire. Sunspot 1078 is turning away from Earth and will soon disappear over the sun's western limb. Readers with solar telescopes are encouraged to catch it before it goes.

User Image



AND THEN TO WORSE...

SOLAR FLARE UPDATE: Sunspot 1079 near the sun's southwestern limb has joined this weekend's flare show (described below) with a series of its own M- and C-class eruptions. Click here for an SDO movie entitled "Blowing Bubbles."

SOLAR FLARES: Sunspot 1081 is crackling with C- and M-class solar flares. Here is a picturesque C6-category blast recorded yesterday, June 12th (0917 UT), by NASA's Solar Dynamics Observatory (SDO):

User Image

Movie:
http://www.spaceweather.com/swpod2010/12jun10/cflare304.mpg

An even stronger M2-class flare on June 12th (0055 UT) sparked a bright flash of extreme ultraviolet radiation, propelled a shock wave through the sun's atmosphere, and hurled a billion-ton coronal mass ejection (CME) into space. The CME is expected to miss Earth--so no auroras.

User Image

Movie of Tsunami:
http://www.spaceweather.com/swpod2010/12jun10/mflare304.mpg

Sunspot 1081 appears to be in a state of slight decay, but that has not stopped the flares. Indeed, the decay may be contributing to magnetic instabilities underlying these explosions. Readers with solar telescopes are encouraged to monitor developments.

User Image







OK, with all that is it any wonder temps are sky rocketing this week... Enough getting creeped out by the sun, here is some other space news:


WELCOME HOME, HAYABUSA:
http://www.isas.jaxa.jp/e/enterp/missions/hayabusa/index.shtml
Japan's Hayabusa spacecraft returned to Earth today carrying samples of asteroid Itokawa. The sample return capsule parachuted to Earth somewhere in Australia's Woomera Test Range (searchers are looking for it now) while the mothership disintegrated in the atmosphere high above ground. Update: NASA's DC-8 flying laboratory was in the air over Australia to record the reentry. Researchers have just released a must-see video.

Update:


First an odd story.

It seems an asteroid is approaching and its orbit CHANGED to miss us... this sounds very odd..

http://www.dailygalaxy.com/my_weblog/2010/05/nasa-could-approaching-space-object-be-artificial.html


User Image

My thoughts are if this thing changed course then either it A) isn't really an asteroid and is a ship and owned by US or... someone else... take the tin foil hat off... or B) it was an asteroid and we used something like HAARP or some other technology to move the asteroid away from us so it wont hit us. I vote the latter..



Now the SUN.... that thing is ticked off...

For the past week we have had major solar flares from B to C. (see above posts.... that behavior continued)


"SMALL" EXPLOSIONS: Tiny new sunspot 1082 is crackling with small solar flares. This one is "only" about as powerful as ten million atomic bombs:

http://www.spaceweather.com/swpod2010/17jun10/bflare.mpg

NASA's Solar Dynamics Observatory recorded the B4-category flare on June 17th. Each seemingly miniscule flash of light in the movie is a continent-sized blast dwarfing any explosion ever produced on Earth by many factors of ten.
Believe it or not, solar physicists do consider this small. On the Richter scale of solar flares, B-flares are near the bottom, producing little or no effect on Earth. The really fearsome explosions are X-flares, more than a thousand times stronger than anything sunspot 1081 is likely to produce. X-flares will become more common as Solar Max approaches in 2013. Until then, relax. It's "only" a B-flare.


FARSIDE BLAST: During the early hours of June 19th, the Solar and Heliospheric Observatory observed a bright coronal mass ejection (CME) emerging from the sun's northwestern limb. Click on the image to set the cloud in motion:

User Image

Nothing exploded on the visible face of the sun, so where did this CME come from? Answer: AR1081. Stationed over the sun's western limb, NASA's STEREO-Ahead spacecraft witnessed the blast: movie. It came from the vicinity of sunspot 1081, the same active region that produced several potent C- and M-class flares one week ago. AR1081 is now transiting the sun's far side, invisible from Earth, but it will turn back in our direction 8 to 10 days from now. Will it still be active then? Stay tuned!

UPDATE: The Solar Dynamics Observatory also recorded an amazing movie of the eruption rising over the sun's northwestern limb
http://sdowww.lmsal.com/sdomedia/ssw/ssw_client/data/ssw_service_100618_203043_9424128/www/ssw_cutout_20100618_221503_aia_304_N37W78_20100618_221502_m.mpg


FATHER'S DAY BLAST: Consider it a Father's Day gift ... from the sun. This morning around 1 a.m. UT, magnetic fields on the sun's eastern limb became unstable and erupted, producing one of the most spectacular explosions of the year. NASA's Solar Dynamics Observatory recorded the action:
http://www.spaceweather.com/swpod2010/20jun10/prom304.mpg
The explosion did not cause a solar flare (a flash of electromagnetic radiation) but it did hurl a massive cloud of magnetized plasma into space: SOHO movie. Because of the blast site's location on the eastern limb, the cloud will not hit Earth. There won't be any geomagnetic storms or auroras. Future eruptions, however, could have greater effect.
User Image








COMET McNAUGHT (C/2009 R1): Comet McNaught is approaching the sun, which makes the comet bright, but also difficult to see. "I had only a 15 minute view before the sky started to get light this morning," reports Parks Squyres, who sends this picture from SaddleBrooke, AZ:
User Image

The comet will continue to brighten as it swings by the sun. Unfortunately, though, after perihelion (closest approach to the sun) on July 2nd, the comet will not only recede from the sun but also from Earth. The final mornings of June could offer our last good look at this blue-green apparition from the outer solar system.
