WISE launched in December and has been toiling away since. This is probably my favourite image, as it's a view of M31 Andromeda Galaxy that we haven't seen before. It looks like something a science fiction illustrator would come up with, but in reality it's a false colour infrared picture of this well known galaxy. I like this so much in fact, it's become my desktop wallpaper!
Some great interpretation of WISE's newest images, as usual, from the Bad Astronomer Phil Plait:http://tinyurl.com/ylluozz
