The whole universe.


Here's the entire universe--everything that exists in the cosmos--in a single snapshot! NASA astronomers created this photo by piecing together more than 2 million images collected by a space telescope called WISE.

NASA launched WISE--the Widefield Infrared Survey Explorer--in 2009. The telescope surveys infrared energy, which is invisible heat energy.

The mission has catalogued more than half a billion space objects, leading to astounding discoveries. It's already found hundreds of massive black holes known as blazars and has imaged the coldest known stars in the universe. These stars, called Y dwarfs, can actually be cooler than room temperature! WISE has also provided one amazing view of the universe.
