Submission + - NASA snaps shot of flashy Mars-bound comet (networkworld.com)

coondoggie writes: NASA today released images of a comet that will make a pass within 84,000 miles of Mars — less than half the distance between Earth and the moon.

NASA said the Hubble Space Telescope captured the image on the left March 11 of comet C/2013 A1, also called Siding Spring, at a distance of 353 million miles from Earth. Hubble can't see Siding Spring's icy nucleus because of its minuscule size. The nucleus is surrounded by a glowing dust cloud that measures roughly 12,000 miles across, NASA said.

Working...
