A full-disk multiwavelength extreme ultraviolet image of the sun taken by the Solar Dynamics Observatory on March 30, 2010. This is one of the 1st images released from the new probe. False colors trace different gas temperatures. Reds are relatively cool (about 60,000 Kelvin, or 107,540 F); blues and greens are hotter (greater than 1 million Kelvin, or 1,799,540 F).
A prominence leaps off the surface of the sun in this new image from NASA's Solar Dynamics Observatory released on April 22, 2010. The prominence occurred on March 30.
The STEREO (Ahead) spacecraft observed this visually stunning prominence eruption on Sept. 29, 2008 in the 304 wavelength of extreme UV light. It rose up and cascaded to the right over several hours, appearing something like a flag unfurling, as it broke apart and headed into space. The material observed is actually ionized helium at about 60,000 degrees. Prominences are relatively cool clouds of gas suspended above the sun and controlled by magnetic forces.
The Solar Dynamics Observatory caught this view of the sun as an active region emerged, expanded and blew out at least four flares over about a 40-hour period (June 11-12, 2010). These flares were about average in terms of their power.
An AIA image in 193 Å after a solar eruption and a flare. The dark regions show the site of evacuated material from the eruption, and the large magnetic loops were formed during the flare as seen by the Solar Dynamics Observatory.
