SUNSPOT SUNSET: The biggest sunspots of Solar Cycle 24 are showing themselves through the clouds at sunset. "Yesterday evening we had a nice view of AR1260, AR1261, and AR1263 from my farm east of Plymouth, Iowa," says Steve Yezek. Two of them are circled in this snapshot:

Caution: Even when the sun is dimmed by low-hanging clouds or haze, focused sunlight can still damage your eyes. Do not look at the sun through unfiltered optics of any kind. A White Light Solar Observing System is the best way to monitor these great sunspots.

Sunspot 1261 has a "beta-gamma-delta" magnetic field that harbors energy for X-class solar flares. Any such eruptions today would be geo-effective as the sunspot is squarely facing Earth.

INCOMING CME: Magnetic fields above sunspot 1261 erupted this morning at 0648 UT, producing an M1-class solar flare. The blast also hurled a bright coronal mass ejection toward Earth. This movie from the STEREO-Ahead spacecraft shows the cloud racing away from the sun at almost 900 km/s. Geomagnetic storms are possible when the CME reaches Earth on or about August 5th. Stay tuned for updates.

MAGNIFICENT SUNSPOT: Double sunspot 1263 is a whopper. Its two dark cores are each wider than Earth, and the entire region stretches more than 65,000 km from end to end. Yesterday in the Netherlands, Emil Kraaikamp took advantage of a break in the clouds and "a few moments of steady air" to capture this magnificent photo:
User Image
"To image this monster, I used a 10-inch Newtonian telescope capped by a white light solar filter," says Kraaikamp. He used the same setup to photograph nearby sunspot 1261. The clarity of both images is impressive. Note the granulation of the stellar surface surrounding the main dark cores. Those are Texas-sized bubbles of plasma rising and falling like water boiling on top of a hot stove.

The magnetic field of sunspot 1263 harbors energy for powerful X-class solar flares. Because the sunspot is turning to face Earth, any such eruptions in the days ahead would likely be geo-effective

Sure is hot out there.... record temps all over the world this week. In Iraq.... it was 127... NOT HEAT INDEX...... How hot is it where you are? Global warming.... yeah, sure its man made... it has nothing to do with the sun.. /sarcasm

M6-CLASS SOLAR FLARE: Earth orbiting satellites have just detected a significant M6-class solar flare. The source appears to be sunspot 1261. Increased energetic proton fluxes are possible in the vicinity of Earth. Stay tuned for updates.

EARTH-DIRECTED BLAST: Sunspot 1261 erupted on August 2nd at 0619 UT, producing a long-duration M1-class solar flare. At the peak of the event, the sunspot's magnetic canopy was beautifully illuminated by extreme ultraviolet radiation, shown here in an image from NASA's Solar Dynamics Observatory:

The blast hurled a CME almost directly toward Earth. Three spacecraft (SOHO, STEREO-A and STEREO-B) tracked the progress of the expanding cloud. Using data from those three points of view, analysts at the GSFC Space Weather Lab made a 3-dimensional model of the CME. According to their work, the cloud left the sun traveling 900 km/s and should reach Earth on August 5th at 0300 UT plus or minus 7 hours. Polar geomagnetic storms are possible when the CME arrives.

STRONG SOLAR ACTIVITY: For the third day in a row, active sunspot 1261 has unleashed a significant M-class solar flare. The latest blast at 0357 UT on August 4th registered M9.3 on the Richter Scale of Flares, almost crossing the threshold into X-territory (X-flares are the most powerful kind). The number of energetic protons around Earth has jumped nearly 100-fold as a result of this event.

The eruption propelled a bright coronal mass ejection (CME) toward Earth. Click on the image to view a movie of the expanding cloud recorded by the Solar and Heliospheric Observatory:

Moving at an estimated speed of 1950 km/s, this CME is expected to sweep up two earlier CMEs already en route. Analysts at the GSFC Space Weather Lab say the combined cloud should reach Earth on August 5th at 13:55 UT plus or minus 7 hours: "The impact on Earth is likely to be major. The estimated maximum geomagnetic activity index level Kp is 7 (Kp ranges from 0 - 9). The flanks of the CME may also impact STEREO A, Mars and Mercury/MESSENGER." High-latitude sky watchers should be alert for auroras.

SPOTTED SUNSETS: During the recent years of deep solar minimum, observers of the sunset grew accustomed to a blank solar disk. News flash: The sunspots are back. "The sunset conditions of August 2nd were just right to show the massive sunspots AR1260, AR1261 and AR1263 to the casual observer who happened to glance at the sun for a brief few moments," reports Stephen W. Ramsden of Atlanta, Georgia. "You could even see the penumbra with the naked eye!" He had a camera handy and snapped this picture:

"The size and broiling movement of these sunspots just boggles the mind," he says. "You could fit every planet in the solar system with all of the known asteroids neatly inside the largest group...wow!"

Caution: Even when the sun is dimmed by low-hanging clouds or haze, focused sunlight can still damage your eyes. Do not look at the sun through unfiltered optics of any kind. A safely-filtered White Light Solar Observing System is the best way to monitor these great sunspots.

ONE DOWN, TWO TO GO: As predicted by analysts at the GSFC Space Weather Lab, the first of three CMEs produced by the recent spate of flare activity reached Earth during the late hours of August 4th. The impact was weak and is not expected to produce strong geomagnetic storms. Two more CMEs are still on the way and, as described below, they may have merged into a single cloud that could produce significant storming when they reach Earth on August 5th around 10:00 UT. A new model of all 3 CMEs is now available; stay tuned for updates.

TTime can be measured in a number of ways. For instance, we can measure the passage of time via the orbital motion of Earth and other planets in the solar system (Dynamical Time). Or we can measure time based on the rotation of Earth on its axis with respect to the stars (Universal Time). Finally, we can measure time through the oscillations of atoms (International Atomic Time).

Universal Time or UT is the precise measure of time used as the basis for all civil time-keeping. Although their exact definitions differ, most readers can assume that Universal Time is equivalent to Greenwich Mean Time or GMT. Universal Time is actually based on the mean sidereal time as measured in Greenwich, England. It's also approximately equal to mean solar time from Greenwich.

Like most other astronomical calculations, eclipse predictions are usually presented in terms of Universal Time. In order to convert eclipse predictions from UT to local time, you need to know what time zone you are in. For North Americans, the conversion from UT to local time is as follows:

Atlantic Standard Time (AST) = UT - 4 hours
Eastern Standard Time (EST) = UT - 5 hours
Central Standard Time (CST) = UT - 6 hours
Mountain Standard Time (MST) = UT - 7 hours
Pacific Standard Time (PST) = UT - 8 hours


For example, let's assume that an eclipse begins in Toledo, Ohio on June 20 at 20:25 UT. Toledo is in the Eastern Standard Time zone, so:

Local Time = 20:25 - 5 hours
= 15:25 (= 3:25 pm)
(didn't know if you guys knew that or not..)

SUBSIDING STORM: Earth's magnetic field is still reverberating from a CME strike on August 5th that sparked one of the strongest geomagnetic storms in years. Registering 8 on the 0 to 9 "K-index" scale of magnetic disturbances, the storm at maximum sparked auroras across Europe and in many northern-tier US states. Travis Novitsky sends this picture from Grand Portage, Minnesota:

NIGHT-TIME SOLAR RADIO BURST: The M9-class solar flare of August 4th produced a burst of shortwave static so powerful that receivers on Earth picked it up after sunset. "A RadioJove observer in Florida recorded the burst when the sun was 38 degrees below the horizon," reports amateur radio astronomer Thomas Ashcraft. Ashcraft's own radio telescope in New Mexico recorded the event 1 hour and 54 minutes after sunset:

User Image

Indeed they are. This event brings to mind the iconic night-time solar radio burst of March 8, 1958. Five radio telescopes at the University of Florida picked up emissions from the sun while observing the planet Jupiter in tthe middle of the night. On the other side of the world, radio astronomers in daylit Australia confirmed that a powerful solar radio burst had taken place at that exact time. The event is described in a 1959 Nature paper by pioneering radio astronomers Alex Smith and Tom Carr. They considered the possibility that solar radio waves might have been reflected by the Moon or carried to the night side of Earth by ionospheric ducting. In tthe end, they could not conclusively explain what happened and to this day night-time solar radio bursts remain a puzzle.


BIG SUNSPOT GETS BIGGER: Behemoth sunspot 1263 has almost doubled in size this weekend. A 28-hour movie from NASA's Solar Dynamics Observatory shows the spot developing a tail that has added some 50,000 km of length to the active region. This development may increase the likelihood of a strong flare. Images: #1, #2, #3

The Earth Has a Ring

Of anti-protons! While it's not as visually cool as what Saturn has going for it, this is still an important development, even if we can't technically "see" the ring with our primitive Earthling eyes.

According to New Scientist, this anti-proton ring joins the previously discovered positron cloud that's also circling the Earth like an invisible shield. Ironically, the anti-protons are 2,000 times more massive than their positron counterparts, but were discovered second. Both are trapped in a donut-like ring called the Van Allen radiation belt that's held in place by the planet's magnetic field.

In the distant future, a spacecraft designed to use anti-protons (or other types of antimatter) as a fuel source could tap into this ring to top off its tanks and head out into the void, said Alessandro Bruno, a member of the University of Rome Tor Vergata team that confirmed the anti-proton area's existence. I'm really looking forward to that not happening in my lifetime!

be generated from a layer of molecular hydrogen above that. With a good
map of the magnetic field, we should be able to tell which it is.”

NASA's $1.1 billion Juno unmanned satellite lifted off from
Cape Canaveral, Florida, at 12:25 p.m. Eastern, on August 5, headed into a
400 million mile journey for a Jupiter arrival in August 2016. Jupiter is 1300 times
larger than Earth, so in a year, Juno will make 33 orbits at speeds up to 9,941 mph
(160,000 kph). At the end of Juno's mission in 2017, the satellite will be
plunged to a fiery death into Jupiter's atmosphere. By then, we might know a lot
more about its magnetic field that is 20,000 times stronger than Earth's
and whether Jupiter has a rocky core, maybe even with mountains.

Gonna throw this one in there as a small story that is loosly related to planetary news... an old story... sort of..

Could it happen again in this warming 21st Century?

201 million years ago. Image in 072211 Science/AAAS.

201 million years ago toward the end of the Triassic period more than 50% of all marine and terrestrial Earth marine life - including insects - died off. New data reported in the July 22, 2011, journal Science by Micha Ruhl, Ph.D., and colleagues from the University of Copenhagen's Nordic Center for Earth Evolution suggest that the extinctions occurred in only 10,000 to 20,000 years. The scientists studied carbon isotopes of sediments and fossils and found at least 12,000 gigatons of methane were suddenly released from the seafloor into the atmosphere during the extinctions. “Methane is only stable under certain temperatures. If it gets warm, it is released,” Dr. Ruhl reports. The cause of the huge and sudden methane release could have been persistent volcanoes that released CO2 into the atmosphere and warmed up global temperatures. Then because methane is a much stronger greenhouse gas than CO2, the methane released from warming waters could have caused the very rapid climate change that killed off so much Earth life. Could seafloor methane erupt again as climate warms in this 21st Century? See Science Magazine.

MAJOR SOLAR FLARE: This morning at 0805 UT, sunspot 1263 produced a powerful X7-class solar flare. NASA's Solar Dynamics Observatory captured the explosion's extreme ultraviolet flash:

User Image
http://www.spaceweather.com/swpod2011/09aug11/x7.mov

The brunt of the explosion was not Earth directed. Nevertheless, a minor proton storm is in progress around our planet, which could affect satellites in high-altitude orbits. Also, radiation from flare created waves of ionization in Earth's upper atmosphere, briefly disrupting communications at some VLF and HF radio frequencies.

User Image
SOHO coronagraphs show a CME emerging from the blast site. The cloud will probably miss Earth. At this time, however, we cannot rule out a glancing blow from the flank of the CME on or about August 11th. Stay tuned for updates.

http://www.spaceweather.com/images2011/17aug11/limbflare.mpg?PHPSESSID=inmoru13ft6pjrsuvguo1pfjd1

to view a specimen recorded by NASA's Solar Dynamics Observatory around 0200 UT on Aug. 17th. So far none of the blasts has been Earth-directed, although this could change in the days ahead as the active region turns to face our planet

VENUS AND THE SOLAR STORM: (Note: No planets were harmed in the production of this movie.) Yesterday, the Solar and Heliospheric Observatory witnessed a spectacular explosion on the sun that seemed to pass perilously close to Venus. Did the cloudy planet survive? Play the movie for answers

User Image

As the movie shows, the CME passed harmlessly. There was no collision, and it wasn't even close. Although Venus seems to be near the sun, the planet is actually more than 100 million kilometers away. The two bodies are "in conjunction" this week as Venus moves almost directly behind the sun. Because of this arrangement, more CME-Venus conjunctions are possible in the days ahead. Check SOHO for the latest images.




METEORITE ALERT: Bill Cooke, head of NASA's Meteoroid Environment Office has issued a meteorite alert for residents of small towns east of Cleveland, Ohio. There could be space rocks on the ground waiting to be found. "On August 8 at 1:22 Eastern Daylight Time, all-sky cameras belonging to the Southern Ontario Meteor Network detected a fireball entering the atmosphere 54 miles above Lake Erie (80.944 W, 41.945 N), moving SSE at 25 km/s (55,900 mph). There is high confidence that this meteor produced meteorites." For one thing, the debris appears to have produced echoes from KCLE's doppler radar in Cleveland; note the circled reflections:

User Image

"The deep atmospheric penetration of this fireball combined with its deceleration and doppler radar echo strongly suggests a fall somewhere in the countryside east of Clevelend," continues Cooke. Pushpins in this Google map show some possible fall locations based on different assumptions about the meteorite's speed and mass. There could be debris anywhere in the countryside around the Ohio towns of Warren, Kinsman, and Hermitage. Readers who find a candidate meteorite are encouraged to contact the Meteoroid Environment Office for further instructions.

Close-up of Vesta poses puzzle

http://www.nature.com/news/2011/110812/full/news.2011.480.html


Quote:
Astronomers keen to look into strange hole on second-largest asteroid.

Ron Cowen
The origin of Vesta's large crater and equatorial ridges is mysterious.NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

Planetary scientists thought they knew what to expect when NASA's Dawn spacecraft returned the first close-up portrait of the giant asteroid Vesta last month. Fuzzy images from the Hubble Space Telescope (HST) taken in 1996 seemed to show that something had taken a big bite out of the asteroid's south polar region1.

The crater was posited as the source of Vesta-like fragments that populate the asteroid belt, and of a surprisingly large fraction of the meteorites found on Earth.

But seconds after viewing the first image, Peter Thomas of Cornell University in Ithaca, New York, shot off an e-mail to other members of the team: "Looks like HST results were fantasy!"

Thomas later realized he had misjudged Dawn's location when he sent that e-mail, but his words give an idea of scientists' surprise. Vesta's huge depression isn't like those of most impact craters: it is ringed by a wall for only about half its circumference, says Dawn team member Paul Schenk of the Lunar and Planetary Institute in Houston, Texas. It also has a large rounded mound in its middle, rather than the usual conical uplift.

Perhaps strangest of all is a series of troughs ringing the asteroid's equator, a feature not seen in any other body in the Solar System and which may be related to the impact and its huge scale.

If it was caused by an impact, the crater is shaping up to be one of the biggest puzzles of the mission, says Chris Russell, principal investigator of the Dawn mission at the University of California, Los Angeles.
Looking for answers

Russell has commissioned a task force of scientists on the Dawn team to solve the puzzle in time for two conferences in October.

New, sharper, images and spectra will help, as will maps of the asteroid's gravity. Dawn is now orbiting Vesta at a distance of about 2,700 kilometres, some six times closer than when the initial observations were made last month.

The task force will use the data gathered from this closer approach to hunt for evidence of whether the hole really was caused by some sort of collision. Tell-tale signs would include rock that has melted and resolidified on the floor of the depression, and a mixture of broken rock and melted material splashed out of the hole by the force of the blow.

Researchers have already come up with several possible explanations for the hole's strange shape. These all assume that the roughly 460-kilometre-wide crater was gouged out by a piece of space debris measuring 40-80 kilometres across.

One idea is that Vesta, which, at 530 kilometres across is the second-largest asteroid in the Solar System, was struck not at its south pole but midway between the pole and the equator. Because it spins rapidly, completing a full rotation in about five hours, Vesta would have reoriented itself so that the gouged-out region became the rock's new south pole.

This would be the most stable configuration for the damaged asteroid, says Schenk. "I don't think we've ever seen before a body with such a large impact and such a high rotation rate," he says.

In January, Martin Jutzi of the University of Bern in Switzerland and Erik Asphaug of the University of California, Santa Cruz, modelled the impact that walloped Vesta and obtained some surprising results2.

They calculate that Vesta completed an entire revolution while the crater was forming. As a result, the debris thrown up by the impact did not settle evenly around the crater, but fell in uneven clumps. This lopsided excavation might explain why a wall runs around only half of the impact site.

The cause of the equatorial troughs remain a mystery, says Asphaug, but they might be the result of material rushing back into the hole created by the impact. "We really don't know the physics when the crater gets to be about the size of the body [it strikes]," he says.

Watch this:

Spacecraft Sees Solar Storm Engulf Earth

August 18, 2011: For the first time, a spacecraft far from Earth has turned and watched a solar storm engulf our planet. The movie, released today during a NASA press conference, has galvanized solar physicists, who say it could lead to important advances in space weather forecasting.

“The movie sent chills down my spine,” says Craig DeForest of the Southwest Research Institute in Boulder, Colorado. "It shows a CME swelling into an enormous wall of plasma and then washing over the tiny blue speck of Earth where we live. I felt very small.”

http://science.nasa.gov/media/medialibrary/2011/08/18/V5_Craig_Science_Gauge_hlfspdH.264.mov

A wide-angle movie recorded by NASA's STEREO-A spacecraft shows a solar storm traveling all the way from the sun to Earth and engulfing our planet. A 17 MB Quicktime zoom adds perspective to the main 40 MB Quicktime movie.

CMEs are billion-ton clouds of solar plasma launched by the same explosions that spark solar flares. When they sweep past our planet, they can cause auroras, radiation storms, and in extreme cases power outages. Tracking these clouds and predicting their arrival is an important part of space weather forecasting.

“We have seen CMEs before, but never quite like this,” says Lika Guhathakurta, program scientist for the STEREO mission at NASA headquarters. “STEREO-A has given us a new view of solar storms.”

STEREO-A is one of two spacecraft launched in 2006 to observe solar activity from widely-spaced locations. At the time of the storm, STEREO-A was more than 65 million miles from Earth, giving it the “big picture” view other spacecraft in Earth orbit have been missing.

When CMEs first leave the sun, they are bright and easy to see. Visibility is quickly reduced, however, as the clouds expand into the void. By the time a typical CME crosses the orbit of Venus, it is a billion times fainter than the surface of the full Moon, and more than a thousand times fainter than the Milky Way. CMEs that reach Earth are almost as gossamer as vacuum itself and correspondingly transparent.

“Pulling these faint clouds out of the confusion of starlight and interplanetary dust has been an enormous challenge,” says DeForest.

Indeed, it took almost three years for his team to learn how to do it. Footage of the storm released today was recorded back in December 2008, and they have been working on it ever since. Now that the technique has been perfected, it can be applied on a regular basis without such a long delay.

Alysha Reinard of NOAA’s Space Weather Prediction Center explains the benefits for space weather forecasting:

“Until quite recently, spacecraft could see CMEs only when they were still quite close to the sun. By calculating a CME's speed during this brief period, we were able to estimate when it would reach Earth. After the first few hours, however, the CME would leave this field of view and after that we were 'in the dark' about its progress.”

“The ability to track a cloud continuously from the Sun to Earth is a big improvement,” she continues. “In the past, our very best predictions of CME arrival times had uncertainties of plus or minus 4 hours,” she continues. “The kind of movies we’ve seen today could significantly reduce the error bars.”

This 17 MB Quicktime zoom adds perspective to the main 40 MB Quicktime movie of the CME engulfing Earth.

The movies pinpoint not only the arrival time of the CME, but also its mass. From the brightness of the cloud, researchers can calculate the gas density with impressive precision. Their results for the Dec. 2008 event agreed with actual in situ measurements at the few percent level. When this technique is applied to future storms, forecasters will be able to estimate its impact with greater confidence.

At the press conference, DeForest pointed out some of the movie’s highlights: When the CME first left the sun, it was cavernous, with walls of magnetism encircling a cloud of low-density gas. As the CME crossed the Sun-Earth divide, however, its shape changed. The CME “snow-plowed” through the solar wind, scooping up material to form a towering wall of plasma. By the time the CME reached Earth, its forward wall was sagging inward under the weight of accumulated gas.

The kind of magnetic transformations revealed by the movie deeply impressed Guhathakurta: “I have always thought that in heliophysics understanding the magnetic field is equivalent to the ‘dark energy’ problem of astrophysics. Often, we cannot see the magnetic field, yet it orchestrates almost everything. These images from STEREO give us a real sense of what the underlying magnetic field is doing.”

All of the speakers at today’s press event stressed that the images go beyond the understanding of a single event. The inner physics of CMEs have been laid bare for the first time—a development that will profoundly shape theoretical models and computer-generated forecasts of CMEs for many years to come.

“This is what the STEREO mission was launched to do,” concludes Guhathakurta, “and it is terrific to see it live up to that promise."

Offering Funds, U.S. Agency Dreams of Sending Humans to Stars
User Image

http://www.nytimes.com/2011/08/18/science/space/18starship.html?_r=1

Quote:
The government agency that helped invent the Internet now wants to do the same for travel to the stars.

In what is perhaps the ultimate startup opportunity, Darpa, the Defense Advanced Research Projects Agency, plans to award some lucky, ambitious and star-struck organization roughly $500,000 in seed money to begin studying what it would take — organizationally, technically, sociologically and ethically — to send humans to another star, a challenge of such magnitude that the study alone could take a hundred years.

The awarding of that grant, on Nov. 11 — 11/11/11 — is planned as the culmination of a yearlong Darpa-NASA effort called the 100-Year Starship Study, which started quietly last winter and will include a three-day public symposium in Orlando, Fla., on Sept. 30 on the whys and wherefores of interstellar travel. The agenda ranges far beyond rocket technology to include such topics as legal, social and economic considerations of interstellar migration, philosophical and religious concerns, where to go and — perhaps most important — how to inspire the public to support this very expensive vision.

The Darpa plan has generated buzz as well as befuddlement in the labs, pubs, diners and Web sites that ring NASA centers both physically and virtually, where the dream of space travel has never died and where a few stubborn bands of scientists and engineers, fueled by science fiction dreams and prophecies, are designing spacecraft that could cross interstellar space, incubating a technology and preserving it for the day when it will be used.

“If you want to have a hobby, why can’t it be designing an interstellar spacecraft?” said Andreas Tziolas, who teaches at the University of Alaska and directs Project Icarus, a worldwide volunteer effort to design a spacecraft that could carry a scientific probe to a nearby star — perhaps Alpha Centauri, 4.4 light-years from here — in a trip that would take less than 100 years.

“This is what we do,” said Louis Friedman, former executive director of the Planetary Society, in Pasadena, Calif., which bills itself as the world’s largest public space organization.

Many scientists wonder if life, especially intelligent life, exists beyond Earth. Some day, the interstellar dreamers vow, the life out there will be us.

People like Dr. Tziolas say the technology already exists or will soon exist to send instruments and perhaps even people to nearby stars, although a human flight could cost hundred of trillions of dollars. The half-million dollars Darpa will award is not enough to build a starship or even to buy a modest office in which to imagine one — but it is enough to start serious fund-raising and, perhaps to invite ridicule from critics of government spending.

An actual human launching is at least a couple of centuries away and, barring the invention of Star Trek-like warp drives, could take additional centuries to complete. Whoever goes on such a journey will not be coming back.

But there are plenty of reasons that humans will eventually summon the political will to make the trip, scientists say, if not for human restlessness that has taken us out of the caves and across the oceans, then to escape being wiped out when the killer asteroid appears or the Sun boils the oceans, which it will do in a couple of billion years.

Another lure could be the discovery of a habitable planet elsewhere, something that could happen in the next few years through the efforts of NASA’s Kepler satellite and related astronomical efforts, according to Jill Tarter, an astronomer at the SETI Institute in Mountain View, Calif., who has devoted her life to the search for extraterrestrials. “This will get real when we have an Earth analogue as a destination,” she said.

David Neyland, Darpa’s director of tactical technology, is at pains to point out that the goal of his project is not an interstellar spacecraft, only a business plan for designing one. The search, he explained, is for an organization, presumably private, that can develop the interstellar vision without government help, carrying the load for the next 100 years, developing valuable technological offshoots the way investing in computer protocols enabled the Internet.

SHAPE-SHIFTING SUNSPOT: Every time you look, sunspot 1271 has a new outline. For the past two days the active region has been in a constant state of change, altering its shape on an hourly basis. Click on the image for 48 hours of shape-shifting:

User Image

These rapid changes have caused the sunspot's magnetic field to criss-cross and tangle. The magnetic field now has a "beta-gamma" configuration that harbors energy for M-class solar flares. Any such flares today would be approximately Earth-directed because the sunspot is not far from disk-center.

Sunspot 1271 is so big, it's catching the attention of observers unaided by solar telescopes. Sarah E. Baur of Anaconda, Montana, noticed it yesterday through the smoke of a nearby fire:

It's alive! Space station's humanoid robot awake

Quote:
CAPE CANAVERAL, Fla. (AP) — NASA's humanoid robot has finally awakened in space.

Ground controllers turned Robonaut on Monday for the first time since it was delivered to the International Space Station in February. The test involved sending power to all of Robonaut's systems. The robot was not commanded to move; that will happen next week.

"Those electrons feel GOOD! One small step for man, one giant leap for tinman kind," Robonaut posted in a Twitter update. (All right, so a Robonaut team member actually posted Monday's tweets under AstroRobonaut.)

The four visible light cameras that serve as Robonaut's eyes turned on in the gold-colored head, as did the infrared camera, located in the robot's mouth and needed for depth perception. One of Robonaut's tweets showed the view inside the American lab, Destiny.

"Sure wish I could move my head and look around," Robonaut said in the tweet.

Robonaut — the first humanoid robot in space — is being tested as a possible astronaut's helper.

The robot's handlers at Mission Control in Houston cheered as everything came alive. The main computers — buried inside Robonaut's stomach — kicked on, as did the more than 30 processors embedded in the arms for controlling the joints.

"Robonaut behaved himself," said deputy project manager Nicolaus Radford. "Oh, Robonaut definitely got an 'A.' He won't be held back a grade, if that's what you want to know."

"It was just very exciting," he said. "It's been a long time coming to get this thing turned on."

The robot was delivered on space shuttle Discovery's final flight. It took this long for the operating software to get up there, and for the astronauts to have enough time to help with the experiment

NASA scientists have discovered stars that are cool enough to touch

Last year, NASA announced that it had discovered 14 of the coldest stars it had ever recorded. The so-called "brown dwarfs" were, at that time, listed among the coldest known stars in our universe.

Now, employing the same instrumentation it used to detect last year's brown dwarfs, NASA has identified six new, even-cooler orbs known as "Y-dwarfs." Y-dwarfs are the coldest members of the brown dwarf family, which makes these stars the coolest of the cool. How cool you ask? Try cooler than the human body.

Brown dwarfs, and Y-dwarfs especially, are what astronomers often refer to as "failed stars;" the low density of these astral bodies prohibits them from fusing atoms at their cores, which in turn keeps them from burning with the enduring heat and intensity typical of other stars (our Sun, for example, has a surface temperature of around 10,000 Fahrenheit, a core temperature as high as 27 million degrees Fahrenheit, and will continue to burn for at least a few billion years).

But astronomers can still learn a lot from these stellar failures, so it's in their best interests to catalog as many of them as possible. Unfortunately, the same characteristics that make these brown dwarfs interesting to study makes them very difficult to find.

Because brown dwarfs lack the mass to keep burning for extended periods of time, they tend to gradually cool and fade, until the only light they emit is found at infrared wavelengths that are invisible to the human eye. In other words, searching for brown dwarfs with a visible-light telescope is damn near impossible. (The image up top is an artist's conception of what a Y-dwarf might look like.)

So how did NASA scientists find the dwarfs? Simple: they built an infrared telescope, and then they stuck it on a satellite. The combination satellite/telescope is called the Wide-field Infrared Survey Explorer, or WISE for short.

WISE's heat-and-IR-sensing capabilities are what allowed it to capture the infrared image pictured here (click to embiggen). The pale green dot at the very center of the photo is WISE 1828+2650, what NASA scientists are calling the record holder for the coldest brown dwarf ever discovered, with an estimated atmospheric temperature of less than 80 degrees Fahrenheit.

But what's really incredible about the discovery of WISE 1828+2650 and the other recently uncovered Y-dwarfs is their proximity to our own solar system. Some of the newly discovered Y dwarfs are a mere nine light years away (Proxima Centauri, the star closest to our solar system, is about four light-years away).

"Finding brown dwarfs near our sun is like discovering there's a hidden house on your block that you didn't know about," said Michael Cushing, a WISE team member at NASA's Jet Propulsion Laboratory. "It's thrilling to me to know we've got neighbors out there yet to be discovered. With WISE, we may even find a brown dwarf closer to us than [Proxima Centauri]."

A destroyed star becomes a planet made of diamonds

An international research team has found an exoplanet made entirely of diamonds. Although this may seem glamorous, researchers think it is only the desolate remains of a star, robbed of its mass by its companion.

Some time ago, a radio telescope picked up the repeated signal of a pulsar. A pulsar is a rapidly-spinning star with a rotation that emits radio waves in strong pulses outwards. This pulsar lay in the plane of the Milky Way, not particularly distinguishing itself from any other pulsar out there. That is, until the astronomers analyzed the spin of the pulsar and found that it was modulated in a certain way. It was almost as if the star was being tugged one way or another via gravity. The only thing that could be making that particular spin was an orbiting planet.

This planet was orbiting fast and close. It was circling the pulsar once every two hours and ten minutes, at a distance just about the radius of Earth's sun. It was about five times the size of earth, a relatively small planet, but it had the mass of Jupiter. This planet should not have gathered so much mass and packed it so tightly when it was so close to a high-gravity star.

Scientists think that it didn't. Actually, the planet is the remains of a star. The pulsar and the newly-discovered planet were once a binary system. As they burnt through their fuel and came closer to one another, one star starting siphoning off the matter of the other. When it was done, it left only a cold, fusion-less planet.

But a pretty one. Judging from the size and mass of the star, scientists think that a very large part of it will be crystalline carbon - the same stuff that diamonds are made of. The theft of most of its fuel left this celestial body a glittering jewel.

NASA Might Have to Control the International Space Station by Remote Control

Space.com reports that, with last week's resupply failure putting NASA behind schedule, Russia needs to get its Soyuz craft back up to speed. If they don't, the ISS will be an empty vessel after the last of the current crew leaves in November.

This wouldn't be the end of the world, as NASA is capable of controlling the ISS from Earth. However, it does put pressure on Russia to see that their Soyuz rockets function so we can continue research there. The Soyuz-U spacecraft that fell back to Earth is similar in design to the craft that will carry the next batch of astronauts to the station. Russian scientists are racing to test their rockets and give them the green light for lift off, but they may not have enough time to meet their deadlines. The current crews scheduled to return mid-September and mid-November. NASA may have no choice but to go it alone thereafter. [Space.com via NPR]

SO MUCH FOR DOOMSDAY: Comet Elenin (C/2010 X1), widely known for inaccurate reports of its threat to Earth, appears to be breaking apart. Observations by amateur astronomer Michael Mattiazzo of Castlemaine, Australia show a rapid dimming and elongation of the comet's nucleus akin to that of Comet LINEAR (C/1999 S4), which also disintegrated when it approached the sun in 2000. Comets are fragile objects, so this development while unexpected comes as no surprise. Readers with pertinent images of Elenin are invited to submit them here.

Past 4 days the Sun has been ticked off.

EARTH-DIRECTED FLARE: This morning at 0150 UT, sunspot 1283 produced an M5.3-class solar flare. NASA's Solar Dynamics Observatory recorded the flash of extreme ultraviolet radiation:
User Image

Because of the sunspot's central location on the solar disk, the eruption was Earth-directed--but is a CME heading our way? Around the time of the explosion, a number of plasma clouds were already billowing away from the sun, adding an element of confusion to the analysis. Tentatively, we expect Earth's magnetic field to receive a glancing blow from a CME on Sept. 8th or 9th

User Image

SOLAR RADIO BURSTS: This week's sharp increase in solar activity has turned the sun into a radio transmitter. Bursts of shortwave static are coming from the unstable magnetic canopy of sunspot 1283. Yesterday in New Mexico, amateur radio astronomer Thomas Ashcraft recorded some samples at 21 MHz: listen. Radio listeners should remain alert for this kind of solar activity as sunspot 1283 continues to seethe.
http://www.spaceweather.com/images2011/07sep11/puffs.mp3


STRONG SOLAR ACTIVITY: Sunspot 1283 is crackling with solar flares. Yesterday, Sept. 6th, the active region produced an M5.3-class eruption at 0150 UT followed by a X2.1-class event at 2220 UT. NASA's Solar Dynamics Observatory recorded this extreme UV flash from the X-flare:

http://www.spaceweather.com/images2011/06sep11/x2flash.mov?PHPSESSID=7b91psbf805a8ildr6dmkqeuu4

The flares produced waves of ionization in Earth's upper atmosphere, briefly altering the propagation of low-frequency radio signals around our planet. Moreover, the two eruptions hurled clouds of plasma (CMEs) in our direction. CME impacts, geomagnetic storms and auroras are expected on Sept. 8-1

X-flares of Solar Cycle 24: There have been only a small number of X-flares since the beginning of new Solar Cycle 24. Here is a complete list so far: Feb. 15, 2011 (X2), March 9, 2011 (X1), Aug. 9, 2011 (X7), Sept. 6, 2011 (X2). Before these four, the previous X-flare occured on Dec.14, 2006, (X1) during old Solar Cycle 23.


STRONG FLARE ACTIVITY CONTINUES: On Sept. 8th at 1546 UT, sunspot 1283 unleashed an M6-class solar flare. This continues the active region's 3-day trend of daily powerful eruptions. Yesterday's blast, an X1.8-class event, produced a bright flash of extreme UV radiation and hurled an inky-dark plume of plasma into space.

^ AWESOME MOVIE

ACTIVE SUNSPOT: Sunspot 1283 is producing flares so intense they are visible through solar telescopes in backyards 93 million miles away. Amateur astronomer Andy Devey photographed this one, and M6-class eruption, from Barnsley UK on Sept. 8th:

User Image

The magnetic canopy of sunspot 1283 has an unstable "beta-gamma-delta" configuration tthat harbors energy for more powerful eruptions. NOAA forecasters estimate a 75% chance of M-flares and a 25% chance of X-flares during the next 24 hour


MERCURY-DIRECTED CME: On Sept 8th around 2300 UT, the SOHO and STEREO spacecraft detected a significant CME emerging from the farside of the sun. Earth is not in the line of fire, but the planet Mercury is. Analysts at the Goddard Space Weather Lab estimate that the cloud will reach the innermost planet on Sept. 9th at 12:00 UT (plus minus 7 hours). Click to view a movie of their CME model:

User Image

NASA's MESSENGER spacecraft is in orbit around Mercury, so it will have a front row seat for the impact. Researchers are keen to learn how Mercury's magnetosphere responds to CMEs. In particular, they wonder if CMEs can overpower Mercury's magnetic field and sputter atoms right off the planet's surface. Thanks to the Goddard forecast, MESSENGER's controllers know the CME is coming, and they can prepare to observe the impact.
