NASA Sees Enthusiastic Response to Asteroid Call for Ideas Posted: 26 Jul 2013 01:58 PM PDT NASA has received more than 400 responses to its request for information (RFI) on the agency's asteroid initiative, Deputy Administrator Lori Garver announced Friday. Original Source

Hubble Eyes a Mysterious Old Spiral Posted: 26 Jul 2013 01:55 PM PDT This striking cosmic whirl is the center of galaxy NGC 524, as seen with the NASA/ESA Hubble Space Telescope. This galaxy is located in the constellation of Pisces, some 90 million light-years from Earth. NGC 524 is a lenticular galaxy.  Lenticular galaxies are believed to be an intermediate state in galactic evolution — they are neither elliptical nor spiral. Spirals are middle-aged galaxies with vast, pin wheeling arms that contain millions of stars.  Along with these stars are large clouds of gas and dust that, when dense enough, are the nurseries where new stars are born. When all the gas is either depleted or lost into space, the arms gradually fade away and the spiral shape begins to weaken.  At the end of this process, what remains is a lenticular galaxy — a bright disc full of old, red stars surrounded by what little gas and dust the galaxy has managed to cling on to.   This image shows the shape of NGC 524 in detail, formed by the remaining gas surrounding the galaxy's central bulge. Observations of this galaxy have revealed that it maintains some spiral-like motion, explaining its intricate structure.    Credit:  ESA/Hubble, NASA,  Acknowledgement: Judy Schmidt Original Source

NASA's WISE Finds Mysterious Centaurs May Be Comets Posted: 26 Jul 2013 12:43 PM PDT The true identity of centaurs, the small celestial bodies orbiting the sun between Jupiter and Neptune, is one of the enduring mysteries of astrophysics. Are they asteroids or comets? A new study of observations from NASA's Wide-field Infrared Survey Explorer (WISE) finds most centaurs are comets. Original Source

NASA Mission Discovers Particle Accelerator in Heart of Van Allen Radiation Belts Posted: 26 Jul 2013 12:40 PM PDT Using data from a NASA satellite, scientists have discovered a massive particle accelerator in the heart of one of the harshest regions of near-Earth space, a region of super-energetic, charged particles surrounding the globe and known as the Van Allen radiation belts.
