WISE shuts its eye

One of my favorite space astronomy missions, WISE, has shut its eye for the last time.

This wasn't unexpected, though! The Wide-field Infrared Survey Explorer was meant to be a short mission, mapping the sky in far-infrared light for a year or so. It needed coolant to chill its detectors, and that ran out last year. On February 1, 2011, it took this one, final image:

It's very much like millions of other images WISE took in its time in space. Below are links to some of my favorite images from WISE, and you really should take a look. They are eerily beautiful, and tell us a lot about the Universe that our eyes cannot perceive.

My congratulations to all my friends at WISE on an amazingly successful mission!
