Fastest Coronal Mass Ejection Observed By STEREO
2012-08-14 11:57:42

[ Watch the Video: STEREO Captures Fastest CME to Date ] Lee Rannals for redOrbit.com - Your Universe Online NASA's STEREO spacecraft has observed the fastest coronal mass ejection (CME) ever seen on the Sun. The Solar TErrestrial RElations Observatory (STEREO) clocked the massive eruption traveling between 1,800 and 2,000 miles per second as it ejected from the sun. NASA said this was the fastest CME ever observed by STEREO, which launched back in 2006. "Between 1,800 and...

Solar Flare Captured By SDO
2012-07-31 13:47:29

Lee Rannals for redOrbit.com - Your Universe Online NASA's Solar Dynamics Observatory (Solar Dynamics Observatory) captured a mid-level solar flare on Saturday, showing us that the sun is getting prepped for its solar maximum. SDO witnessed the image on the active region of the sun named AR 1532 in the 131 Angstrom wavelength. This wavelength is typically colorized as teal, and is particularly good for catching flares, NASA said. Solar flares emit powerful bursts of radiation, which...

Art And Science Collide in New Solar Imaging Technique
2012-07-22 07:05:56

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online In what can be described as a melding of astronomy and post-Impressionist art, one NASA solar scientist has developed a new technique that uses bright, bold colors to share information about the heating and cooling of various parts of the sun. Nicholeen Viall of the NASA Goddard Space Flight Center in Greenbelt, Maryland innovated this new method, which uses various hues splashed across a yellow background...

Solar Corona Captured In Highest Resolution Ever
2012-07-21 05:29:44

[ Video 1 ] | [ Video 2 ] redOrbit Staff & Wire Reports - Your Universe Online A telescope launched on board a NASA sounding rocket earlier this month has captured the highest-resolution images of the sun's corona, the US space agency announced on Friday. The 16-megapixel images of the million-degree atmosphere of the sun were captured in an extreme-ultraviolet wavelength of light by the High Resolution Coronal Images (Hi-C) telescope, according to the Harvard-Smithsonian Center...

Coronal Mass Ejection Unlikely To Reach Earth
2012-07-21 04:31:52

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online A coronal mass ejection (CME) associated with a solar flare emitted early Thursday morning is unlikely to reach Earth, but it could affect one of the two Solar Terrestrial Relations Observatory (STEREO) satellites currently orbiting the sun, NASA officials posted on the agency's official website. According to the US space agency, the sun emitted a mid-level (M7.7) flare on July 19. The flare, which began at...

Aurora Australis Glowing Over Concordia Station
2012-07-20 15:27:23

A stunning image showing Aurora Australis — the Southern Lights — glowing over Concordia station in the Antarctic, one of the remotest places on Earth, on 18 July 2012. It was taken by ESA-sponsored scientist Alexander Kumar and his colleague Erick Bondoux from about 1 km from the station, located in the Antarctic at 75°S latitude. The French—Italian Concordia station's programme of research includes glaciology, human biology and the atmosphere. ESA uses the base to...

Solar Storm Expected To Reach Earth Saturday Morning
2012-07-14 04:10:29

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online A solar storm, scheduled to arrive Saturday morning and last through the end of the day on Sunday, is expected to put on a show for sky-gazers but should otherwise have little to no effect, according to scientists. According to the Associated Press (AP), the storm began on Thursday, as the sun unleashed a powerful solar flare -- the sixth recorded by scientists this year. The NOAA Space Weather Prediction...

Photosphere -- The photosphere of an astronomical object is the region at which the optical depth becomes one. In other words, the photosphere is the place where an object stops being transparent. It is typically used to describe the Sun or another star. Because stars are large balls of gas, they have no solid surface. However, there is a depth at which the gas stops being transparent to photons, and this depth provides a visual surface to the star. The Sun's photosphere has a...

Corona -- The corona is the luminous "atmosphere" of the Sun extending millions of kilometers into space, most easily seen during a total solar eclipse. An interesting feature of the corona is the fact that it is much hotter than the visible "surface" of the Sun; the photosphere is approximately 6000°C compared to the corona at over one million °C. The corona is much less dense than the photosphere, however, and so produces less light. The exact mechanism by which the corona is...

Chromosphere -- The chromosphere (literally, "color sphere") is a thin layer of the Sun's atmosphere just above the photosphere, roughly 10,000 kilometers deep. The chromosphere is more visually transparent than the photosphere. The most common solar feature within the chromosphere are spicules, long thin fingers of luminous gas which appear like the blades of a huge field of fiery grass growing upwards from the photosphere below. Spicules rise to the top of the chromosphere and then sink...

Solar Wind -- Solar wind, a stream of particles (mostly high-energy protons ~ 500 Kev) that is continually ejected from the surface of the Sun. The composition of this plasma is identical to the Sun's corona, 73% hydrogen and 25% helium with the remainder as trace impurities, and is ionized. Near Earth, the velocity of the solar wind varies from 200km/s-889km/s. The average is 450 km/s. Approximately 3000 tons of material is lost from the Sun every hour as solar wind. Since solar...

Solar Maximum -- The Sun, a roiling ball of plasma, occupies its place in space approximately 93 million miles from Earth. Though it seems simple to inhabitants of this planet -- the Sun shines, giving light and heat -- the processes occurring in the Sun are so complex that many scientists devote their careers to just one aspect of solar activity. Changes in the activity of the Sun particularly engage solar scientists. Whether fluctuations in the solar magnetic field, expulsions of...
