NASA's SDO Observes Fast-Growing Sunspot

NASA - NASA's SDO Observes Fast-Growing Sunspot: "The bottom two black spots on the sun, known as sunspots, appeared quickly over the course of Feb. 19-20, 2013. These two sunspots are part of the same system and are over six Earths across. This image combines images from two instruments on NASA's Solar Dynamics Observatory (SDO): the Helioseismic and Magnetic Imager (HMI), which takes pictures in visible light that show sunspots and the Advanced Imaging Assembly (AIA), which took an image in the 304 Angstrom wavelength showing the lower atmosphere of the sun, which is colorized in red.

Asteroid 2012 DA14 to Whiz Past Earth

Published on Feb 7, 2013 - The small near-Earth asteroid 2012 DA14 will pass very close to Earth on Feb. 15, 2013. It will be so close that it will pass inside the ring of geosynchronous weather and communications satellites. Asteroid 2012 DA14 will be closest to Earth at about 11:24 a.m. PST (2:24 p.m. EST and 1924 UTC), on Feb. 15, when it will be at a distance of about 27,700 kilometers (17,200 miles) above Earth's surface. NASA's Near-Earth Object Program Office can accurately predict the asteroid's path with the observations obtained, and it is therefore known that there is no chance that the asteroid might be on a collision course with Earth. Nevertheless, the flyby will provide a unique opportunity for researchers to study a near-Earth object up close. Includes interview with Donald K. Yeomans, Manager of NASA's Near-Earth Object Program Office, Jet Propulsion Laboratory. For more info: http://www.nasa.gov/topics/solarsyste....
