Though built from the same star stuff as our Sun, these celestial runts aren't bulky enough to catch fire from nuclear fusion. NASA's Wide-field Infrared Survey Explorer (WISE) has discovered fewer of these 'almost stars' than earlier predicted.
12 June 2012, 12:44 PM ET
Observations by NASA's Wide-field Infrared Survey Explorer (WISE) have revealed a surprise — there are fewer brown dwarfs in our cosmic backyard than previously believed.

A galaxy whose light has taken 13 billion years to reach us has been sighted.
04 June 2012, 07:58 PM ET
Research suggests that the CID-42 galaxy collided with another galaxy, their black holes merged and ejected out of the newly formed star system at astonishing speeds. Albert Einstein predicted that this phenomenon is caused by gravitational waves.
