CBS News : Astronomers have discovered the closest new star to us that’s been spotted in 63 years. The new find, a brown dwarf called UGPS 0722-05 , is less than 10 light years from here, and the coldest brown dwarf ever discovered. Brown dwarfs have so little mass that they never get hot enough to sustain the nuclear fusion reactions that power stars like the sun. Still, they do shine, because they glow from the heat of their formation, then cool and fade.
