The immense Andromeda galaxy, also known as Messier 31 or simply M31, is captured in full in this new image from NASA's Wide-field Infrared Survey Explorer, or WISE.
Comet Siding Spring appears to streak across the sky like a superhero in this new infrared image from NASA's Wide-field Infrared Survey Explorer, or WISE.
Is it a bird, or a plane? No, it's comet Siding Spring streaking across the sky, as seen by NASA's Wide-field Infrared Survey Explorer, or WISE.
This image of a dense cluster of galaxies was captured by NASA's Wide-field Infrared Survey Explorer, or WISE.
This image from NASA's Wide-field Infrared Survey Explorer, or WISE, highlights the Andromeda galaxy's older stellar population in blue.
This image from NASA's Wide-field Infrared Survey Explorer, or WISE, highlights the dust that speckles the Andromeda galaxy's spiral arms.
The red smudge at the center of this picture is the first comet discovered by NASA's Wide-Field Infrared Survey Explorer, or WISE.
The red dot at the center of this image is the first near-Earth asteroid discovered by NASA's Wide-Field Infrared Survey Explorer, or WISE .
This infrared snapshot of a region in the constellation Carina near the Milky Way was taken shortly after NASA's Wide-field Infrared Survey Explorer (WISE) ejected its cover.
This diagram shows a brown dwarf in relation to Earth, Jupiter, a low-mass star and the sun.
Astronomers think there are roughly as many brown dwarfs as regular stars like our sun, but brown dwarfs are often too cool to find using visible light.

An engineer loads hydrogen gas into the Wide-Field Infrared Survey Explorer, or WISE, in a clean room at the Vandenberg Air Force Base, Calif.
This infrared image of Ned Wright, WISE principal investigator at UCLA, shows heat, with warm objects appearing brighter than cool ones.
This infrared view of the whole sky highlights the flat plane of our Milky Way galaxy (line across middle of image).
The image on the left shows an infrared view of the center of our Milky Way galaxy as seen by the 1983 Infrared Astronomical Satellite (IRAS), which surveyed the whole sky with only 62 pixels.
This diagram shows a bird's eye view of our asteroid belt, which lies between the orbits of Mars (red) and Jupiter (purple).
This artist's conception shows NASA's Wide-field Infrared Survey Explorer, or WISE, mapping the whole sky in infrared.
This image shows the bottle-like tank that houses the science instrument on NASA's Wide-field Infrared Survey Explorer, or WISE, mission (some say it resembles the Star Wars robot R2-D2).
The telescope on the Wide-field Infrared Survey Explorer, or WISE, is shown here with the aperture cover removed.
