April Flowers for redOrbit.com - Your Universe Online NASA's Near-Earth Orbit Wide-field Infrared Survey Explorer spacecraft, or NEOWISE for short, made the most comprehensive survey to date of asteroids and comets during its first tour of service. Now, NEOWISE has returned to service, and has sent its first set of test images back to Earth in preparation for a renewed mission. More than 34,000 asteroids were discovered, and 158,000 were characterized throughout the solar system during...

April Flowers for redOrbit.com - Your Universe Online A new and improved atlas and catalog, brimming with data on three-quarters of a billion objects detected during two full scans of the sky, were released by NASA on Friday from their Wide-field Infrared Survey Explorer (WISE) mission. In 2010, WISE scanned the entire sky in infrared light, snapping a dozen pictures of every star and galaxy. The spacecraft ran out of the coolant needed to chill some of its heat-seeking detectors in...

Lee Rannals for redOrbit.com – Your Universe Online Similar to reading tree rings, astronomers are able to read the rings in a galaxy’s disk to help gain a better understanding of its past. Scientists using NASA's Wide-field Infrared Survey Explorer (WISE) and Galaxy Evolution Explorer (GALEX) have gained evidence supporting the “inside-out” theory of galaxy growth, which says that formation starts with the bursts of star formation. "Initially, a rapid star-forming period...
