EruptionCredit: JAXA/HinodeThursday, February 9, 2012: On Jan. 27, 2012, a large X-class flare erupted from an active region on the sun, near the solar west limb. X-class flares represent the most powerful of all solar events. The X-ray telescope on Hinode spacecraft captured this image of the flare, showing an emission from plasma heated to greater than eight million degrees during the energy-release process of the flare.

East Coast PanoramaCredit: NASAWednesday, February 8, 2012: The East Coast of the United States glows at night, as seen from the International Space Station. This looks generally northeastwards with the Philadelphia-New York City-Boston corridor at bottom center. The western shoreline of Lake Ontario with Toronto lies on the left edge. Montreal, Quebec, Canada, gleams as the bright spot near the center. Atmospheric limb and light activity from the Aurora Borealis appear intertwined due to an optical illusion. Photo taken Jan. 29, 2012.

NuSTAR in the SkyCredit: NASA Kennedy Space Center (via Twitter @NASAKennedy)Monday, February 6, 2012: NuSTAR, The Nuclear Spectroscopic Telescope Array, will image the sky for the first time in the high energy X-ray (6-79 keV) region of the electromagnetic spectrum. Our view of the universe in this spectral window has been limited previously. NuSTAR is scheduled to launch March 14, 2012, from an aircraft operating out of Kwajalein Atoll in the Marshall Islands. Here, NuSTAR is seen undergoing a solar array illumination test. Image released via Twitter Feb. 3, 2012.

Vesta and Mercury Are All Right TonightCredit: Vesta: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA; Mercury: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of WashingtonThursday, February 2, 2012: Two images displayed together show the fruits of NASA’s labors. In 2011, MESSENGER spacecraft went into orbit around Mercury (left), and Dawn spacecraft orbited main-belt asteroid Vesta (right), sending back the images seen here. Both spacecraft were the first to orbit their respective subjects. MESSENGER and Dawn are missions in NASA's lowest-cost Discovery program. Vesta has a much more irregular shape than Mercury, as a result of Mercury's far larger gravity, which squeezed the planet into a sphere. Mercury possesses a mass about 1300 times greater than that of Vesta.
