According to NASA, this is a picture of a Klingon Bird of Prey hurtling through space at 11,000 miles per hour.
Or it may be a comet, the result in this case of 2 asteroids colliding. It’s interesting because it’s something that hasn’t been seen before. First there’s the oddly distinct X shape at the beginning of the tail. Then there’s the fact that the comet’s nucleus is OUTSIDE THE TAIL ALL TOGETHER! Normally, a comet’s tail is produced when the nucleus heats up and starts shedding it’s mass, usually engulfing the head in a gaseous cloud. This comet is too far out for that. According to NASA, “P/2010 A2 may have a different origin. It orbits in the warm, inner regions of the asteroid belt where its nearest neighbors are dry rocky bodies lacking volatile materials” which makes it likely that that the debris tail was produce via an impact rather than the normal solar melting way.
Anyway, check out NASA‘s site for high rez pictures and bigger words than I care to use.
