NASA Scientists Discover Coldest, Darkest Stars Ever Found

Using the Wide-field Infrared Survey Explorer (WISE), NASA was able to see the faint glow of six Y dwarfs about 40 lightyears away from the sun. Y dwarfs are of the brown dwarf family of stars, which are referred to as "failed" stars, because they are not large enough to fuse atoms to their cores, thus lacking the atomic energy required to to burn for a long time (like our sun), and they eventually cool to the point where they only emit infrared light.

Amongst the Y dwarfs found, WISE 1828+2650 was found to be 80 degrees Fahrenheit, which happens to hold the record for the coldest star found to date.
