NASA Captures New Images of Asteroid 2005 YU55 Passing Earth November 7,8 & 11, 2011 NASA's Deep Space Network antenna in Goldstone, Calif. has captured new radar images of Asteroid 2005 YU55 passing close to Earth. The asteroid safely will fly past our planet slightly closer than the moon's orbit on Nov. 8. Scientists have also generated a short movie clip of asteroid 2005 YU55 See Asteroid Images See Asteroid Movie See Updated Asteroid Movie

NASA in Final Preparations for Nov. 8 Asteroid Flyby October 26, 2011 NASA scientists will be tracking asteroid 2005 YU55 with antennas of the agency's Deep Space Network at Goldstone, Calif., as the space rock safely flies past Earth slightly closer than the moon's orbit on Nov. 8. Scientists are treating the flyby of the 1,300-foot-wide (400-meter) asteroid as a science target of opportunity - allowing instruments on "spacecraft Earth" to scan it during the close pass.

NASA Says Comet Elenin Gone and Should Be Forgotten October 25, 2011 Comet Elenin is no more. Latest indications are this relatively small comet has broken into even smaller, even less significant, chunks of dust and ice. This trail of piffling particles will remain on the same path as the original comet, completing its unexceptional swing through the inner solar system this fall. Full Story
