It is sometimes referred to as the southern Pinwheel galaxy. What's special about WISE is its ability to see through impenetrable veils of dust, picking up the heat glow of objects that are invisible to regular telescopes.

Worried about Earth-threatening asteroids? One of NASA's newest space telescopes has spotted 25,000 never-before-seen asteroids in just six months.
Ninety-five of those are considered "near Earth," but in the language of astronomy that means within 30 million miles. Luckily for us, none poses any threat to Earth anytime soon.
Called WISE for Wide-field Infrared Survey Explorer, the telescope completes its first full scan of the sky on Saturday and then begins another round of imaging.
