March 24 (UPI) -- A record breaking brown dwarf, newly discovered by an international team of astronomers, is the most massive and 'purest' yet measured.
SDSS J0104+1535 is located 750 light years away along the outskirts of the Milky Way galaxy, a region known as the halo. The brown dwarf and its stellar neighbors are the oldest in the galaxy. Astronomers estimate the mass formed 10 billion years ago.
