NASA’s new Wide-field Infrared Survey Explorer (WISE) spacecraft is mapping the sky like never before. Among its first images is Comet Siding Spring, which flashes across the sky impressively in this infrared image. Observers in Australia discovered the comet, also known as C/2007 Q3, in 2007.

Our neighboring galaxy, Andromeda, also goes by the names Messier 31 or M31. Here, it is captured in full in this new image taken by NASA’s WISE space telescope.
