Swift's UVOT acquired this image of Comet Garradd (C/2009 P1) on
April 1, 2012, when the comet was 142 million miles away, or 636
times farther than the moon. Red shows sunlight reflected from
the comet's dust; violet shows ultraviolet light produced by
hydroxyl (OH), a fragment of water. NGC 2895 is a barred spiral
galaxy located 400 million miles away in the constellation Ursa
Major. The UVOT image (outlined) is placed within a wider
visible image of the region from the Digital Sky Survey. Credit:
