NASA SDO - Twist & Eclipse

Over the past 24 hours we have seen some beautiful solar events. None of them have a direct impact on Earth, but they are astonishing to watch. It just shows how an active Star our Sun really is. Far from boring. On December 8, 2011 a twisting prominence eruption occurred on the lower eastern limb. The view through the AIA 304 angstrom filter shows us this beautiful eruption. In the early hours of December 9, 2011 SDO observed a little bit of a different eclipse. An erupting cloud of plasma was eclipsed by a dark magnetic filament. The eruption is still on the far side of the Sun, behind the eastern limb and is slowly moving forward and over the limb sometime next week. In front you can observe the filament of relatively cool dark material floating across the Sun's surface in the foreground. That filament partially blocks the view of the hot plasma eruption behind it. Credit: NASA SDO

NASA SDO - Today's Un-Boring Sun; December 7, 2011

December 7, 2011; Today's Sun in various wavelengths showing various temperatures and layers of the Sun. Not only that, but we also added the Sun's magnetic field lines to the view. These images were taken at approx. the same time We start off looking at the 6,000 degrees C. Photosphere. See the various sunspots on the "surface" of the Sun? Now let's transition into the region between the Chromosphere and the Corona, at about 1 million degrees C. From there we go into a composite of three different wavelengths showing temperatures up to 2 million degrees C. And at the end we add the complex field of Magnetic Field lines to the various active regions. And who says the Sun is boring? Credit: NASA SDO Thanks to Steele Hill

NASA SDO - Filament Snap, November 14, 2011

And within just a few hours the very massive filament (see post from earlier today) is approx. 1/3 shorter. This movie shows the developments from 13:00 to 16:00 UT on November 14, 2011. A solar prominence (also known as a filament when viewed against the solar disk) is a large, bright feature extending outward from the Sun's surface. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's hot outer atmosphere, called the corona. A prominence forms over timescales of about a day, and stable prominences may persist in the corona for several months, looping hundreds of thousands of miles into space. Scientists are still researching how and why prominences are formed. The red-glowing looped material is plasma, a hot gas comprised of electrically charged hydrogen and helium. The prominence plasma flows along a tangled and twisted structure of magnetic fields generated by the sun's internal dynamo. An erupting prominence occurs when such a structure becomes unstable and bursts outward, releasing the plasma. Credit: NASA SDO

NASA SDO - Three in Profile

Three energized active regions that were lined up latitudinally (along a North-South line) rotated into profile view at the Sun's edge and put on a good solar show (Oct. 21-23, 2011). They were observed in extreme ultraviolet light. The magnetic forces of the active regions were feverishly connecting and reconnecting the entire time. Towards the end of the clip, the middle region spurted off a burst of plasma and then the upper one erupted with a flare, followed by cascades of bright loops reorganizing themselves above it. SDO's high resolution images and fast cadence of images let us see a level of detail never before possible. Credit: NASA SDO

NASA SDO - X5.4-class Solar Flare, March 7, 2012

Right at midnight UT time the active region 1429 unleashed a powerful X5.4-class solar flare. X-class flares are the strongest of the flares. They are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. It appears that right after the large X5.4 flare another slightly lower, X1 flare (5 times smaller) occurred. You can clearly see a wave going across the Sun. We are still gathering data and the Space Weather Forecast Lab will be having updates available soon. Credit: NASA SDO

NASA SDO - Spectacular Prominence Eruption, June 7, 2011

The Sun unleashed an M-2 (medium-sized) solar flare with a substantial coronal mass ejection (CME) on June 7 that is visually spectacular. The large cloud of particles mushroomed up and fell back down looking as if it covered an area of almost half the solar surface. SDO observed the flare's peak at 1:41 AM EST. SDO recorded these images in extreme ultraviolet light and they show a very large explosion of cool gas. It is somewhat unique because at many places in the eruption there seems to be even cooler material -- at temperatures less than 80,000K. When viewed in SOHO's coronagraphs, the event shows bright plasma and high-energy particles roaring from the Sun. This Earth-directed CME is moving at 1400 km/s according to NASA models. Due to its angle, however, effects on Earth should be fairly small. Nevertheless, it may generate space weather effects here on Earth in a few days. Credit: NASA SDO

NASA Science - The Surprising Power of a Solar Storm

A recent flurry of eruptions on the sun did more than spark pretty auroras around the poles. NASA-funded researchers say the solar storms of March 8th through 10th dumped enough energy in Earth's upper atmosphere to power every residence in New York City for two years. "This was the biggest dose of heat we've received from a solar storm since 2005," says Martin Mlynczak of NASA Langley Research Center. "It was a big event, and shows how solar activity can directly affect our planet." Mlynczak is the associate principal investigator for the SABER instrument onboard NASA's TIMED satellite. SABER monitors infrared emissions from Earth's upper atmosphere, in particular from carbon dioxide (CO2) and nitric oxide (NO), two substances that play a key role in the energy balance of air hundreds of km above our planet's surface. "Carbon dioxide and nitric oxide are natural thermostats," explains James Russell of Hampton University, SABER's principal investigator. "When the upper atmosphere (or 'thermosphere') heats up, these molecules try as hard as they can to shed that heat back into space." That's what happened on March 8th when a coronal mass ejection (CME) propelled in our direction by an X5-class solar flare hit Earth's magnetic field. (On the "Richter Scale of Solar Flares," X-class flares are the most powerful kind.) Energetic particles rained down on the upper atmosphere, depositing their energy where they hit. The action produced spectacular auroras around the poles and significant1 upper atmospheric heating all around the globe. "The thermosphere lit up like a Christmas tree," says Russell. "It began to glow intensely at infrared wavelengths as the thermostat effect kicked in." For the three day period, March 8th through 10th, the thermosphere absorbed 26 billion kWh of energy. Infrared radiation from CO2 and NO, the two most efficient coolants in the thermosphere, re-radiated 95% of that total back into space. In human terms, this is a lot of energy. According to the New York City mayor's office, an average NY household consumes just under 4700 kWh annually. This means the geomagnetic storm dumped enough energy into the atmosphere to power every home in the Big Apple for two years. "Unfortunately, there's no practical way to harness this kind of energy," says Mlynczak. "It's so diffuse and out of reach high above Earth's surface. Plus, the majority of it has been sent back into space by the action of CO2 and NO." During the heating impulse, the thermosphere puffed up like a marshmallow held over a campfire, temporarily increasing the drag on low-orbiting satellites. This is both good and bad. On the one hand, extra drag helps clear space junk out of Earth orbit. On the other hand, it decreases the lifetime of useful satellites by bringing them closer to the day of re-entry. The storm is over now, but Russell and Mlynczak expect more to come. "We're just emerging from a deep solar minimum," says Russell. "The solar cycle is gaining strength with a maximum expected in 2013." More sunspots flinging more CMEs toward Earth adds up to more opportunities for SABER to study the heating effect of solar storms. "This is a new frontier in the sun-Earth connection," says Mlynczak, and the data we're collecting are unprecedented." Credit: NASA Science

NASA - Aurorae from Space

Lately, the International Space Station has been flying through geomagnetic storms, giving astronauts an close-up view of the aurora borealis just outside their windows. These videos were taken by the crew of Expedition 30 on board the International Space Station. First, get an introduction into the beauty of aurorae. 1st Segment: The sequence of shots was taken March 3, 2012 from 17:59:48 to 18:16:25 GMT, on a pass from eastern Kenya, near the Indian Ocean, to the South Indian Ocean, east of the Kerguelen Islands. This video begins as the ISS travels southeast from eastern Africa over the Arabian Sea and the Indian Ocean. The first land we see is that of the Mauritius and Reunion Islands east of Madagascar. The pass continues over the Indian Ocean, where there are heavy clouds blocking the view of the water. Finally, the Aurora Australis begins to appear, as well as a faded view of the Milky Way. 2nd Segment: The sequence of shots was taken March 4, 2012 from 17:19:17 to 17:27:10 GMT, on a pass over the South Indian Ocean. This video again focuses on the Aurora Australis as the ISS passes over the South Indian Ocean, from northeast of the Kerugelen Islands to south of Australia. The streaks of the aurora are very visible and active in this video, as the ISS passes right over the green lights. 3rd Segment: The sequence of shots was taken March 10, 2012 from 14:49:58 to 15:05:37 GMT, on a pass from the South Indian Ocean to southeast New Zealand. This video mainly focuses on the Aurora Australis over the Southern Hemisphere. As the ISS traveled southeast and then northeast, the crew captured the bands of the Aurora Australis as the Milky Way made an appearance in the star field. Credit: NASA ISS/JSC/Science@NASA

NASA | Massive Solar Flare gets HD Close Up

Take a closer look at the flare that erupted on March 6, 2012. This movie of the March 6, 2012 X5.4 flare was captured by the Solar Dynamics Observatory (SDO) in the 171 and 131 Angstrom wavelength. One of the most dramatic features is the way the entire surface of the sun seems to ripple with the force of the eruption. This movement comes from something called EIT waves -- because they were first discovered with the Extreme ultraviolet Imaging Telescope (EIT) on the Solar Heliospheric Observatory. Since SDO captures images every 12 seconds, it has been able to map the full evolution of these waves and confirm that they can travel across the full breadth of the sun. The waves move at over a million miles per hour, zipping from one side of the sun to the other in about an hour. The movie shows two distinct waves. The first seems to spread in all directions; the second is narrower, moving toward the southeast. Such waves are associated with, and perhaps trigger, fast coronal mass ejections, so it is likely that each one is connected to one of the two CMEs that erupted on March 6.

NASA SDO - X-class Solar Flares & Solar Tsunami, March 7, 2012

On March 7, 2012 just a few minutes after midnight UT time the active region (AR11429) unleashed two strong X-class flare. The first, X5.4-class, showed a very bright flare, the second right after, X1-class, hurled a second coronal mass ejection into Space. Also seen can be a wave going across the Sun at approx. 1,000,000 mph - also known as a Solar Tsunami. Here are various views of this events over a couple of hours, including some close-up views of the Sunspot 1429. Credit: NASA SDO & Dr. A. Kosovichev, HMI

NASA SDO - M8.7-Class Solar Flare from January 23, 2012

The Chinese New Year certainly started with a bang this morning. At approx. 04:00 UT a strong and long duration M8.7-class solar flare exploded from Active Region 1402. NASA SDO captured this event and thanks to ESA/NASA SOHO and NASA STEREO Behind spacecrafts, we have also learned of a very quick moving Coronal Mass Ejection. The CME is traveling at approx. 2,200 km per second and the Goddard Space Weather Lab predicts the arrival of this CME on earth to be January 24, 2012 at approx. 14:18 UT (+/- 7 hours). It also shows that Mars will get hit too, several hours after Earth. These kinds of events can cause problems for spacecrafts in geosynchronous, polar and other orbits passing could be affected by the cloud's arrival. In addition, strong geomagnetic storms are possible, so high-latitude sky watchers should be alert for Aurorae. Credit: NASA SDO

NASA SDO - Plasma Indirection

As if it could not make up its mind . . . darker, cooler plasma slid and shifted back and forth above the Sun's surface seen here for 30 hours (Feb. 7-8, 2012) in extreme ultraviolet light. An active region rotating into view provides a bright backdrop to the gyrating streams of plasma. The particles are being pulled this way and that by competing magnetic forces. They are tracking along strands of magnetic field lines. This kind of detailed solar observation with high-resolution frames and a four-minute cadence was not possible until SDO, which launched two years ago on Feb. 11, 2010. So it's our 2nd Anniversary!

NASA SDO - Lovely Loops

The Lovely Loops A close-up view of the Sun's edge shows vast loop structures made of superheated plasma, just one of which is the size of several Earths. These loops can have a wide range of temperatures, many reaching several million degrees Kelvin. The upper one of a pair of new, solar active regions that just rotated into view offered a beautiful profile view of those cascading loops spiraling above it (Jan. 15-16, 2012) following a solar flare eruption. With its ability to capture the Sun in amazing detail, SDO observed it all in extreme ultraviolet light. This particular video clip used an image every minutes to present the motion.

Big New ExoPlanet Haul

From EsoCast in 1080p, comes the announcement of a rash of new planet discoveries. Astronomers using ESO's leading exoplanet hunter HARPS have today announced more than fifty newly discovered planets around other stars. Among these are many rocky planets not much heavier than the Earth. One of them in particular orbits within the habitable zone around its star. Among the new planets just announced by scientists, sixteen are super-Earths - rocky planets up to ten times as massive as Earth. This is the largest number of such planets ever announced at one time. A planet in orbit causes its star to regularly move backwards and forwards as seen from Earth. This creates a tiny shift of the star's spectrum that can be measured with an extremely sensitive spectrograph such as HARPS. In their quest to find a rocky planet that could harbor life, astronomers are now pushing HARPS even further. They have selected ten well-studied nearby stars similar to our Sun. Earlier observations showed that these were ideal stars to examine for even less massive planets. After two years of work, the team has found five light super-Earths around three of the stars. These planets are very good candidates for future observations looking for evidence of life. One of the newly found planets, named HD 85512 b, orbits inside the habitable zone. This is the narrow area around a star where water can exist in liquid form. Astronomers estimate that liquid water could possibly be present on this planet if it is a rocky world that has more than 50% cloud cover. By looking carefully at the results from the first 8 years of HARPS observations, the team has found that around 40% of stars similar to the Sun harbor at least one planet lighter than Saturn. These new results lead astronomers to believe that they could soon find more super-Earths in the habitable zones of their stars with HARPS. These planets will be great targets for powerful future telescopes to try to study their atmospheres looking for evidence of life. Thanks to HARPS, the search for another Earth elsewhere in the galaxy is picking up pace!
