Brown dwarfs discovered 6.5 light years away

When NASA launched the WISE satellite in 2009, astronomers hoped it would be able to spot loads of cool, dim objects known as brown dwarfs. Bigger than a planet, a brown dwarf is not quite a star, either—it is too small to sustain the nuclear fusion reactions that turn hydrogen to helium. But it may burn to some degree, using a heavy isotope of hydrogen called deuterium as fusion fuel.

Because brown dwarfs are so dim, it is entirely possible that some of them lie very close to the sun—as close as any known star—and have yet to be discovered. But more than three years after WISE (short for the Wide-Field Infrared Survey Explorer) launched, the map of the sun’s immediate vicinity has remained largely unchanged. Until now.



Interesting discovery. I wonder how many more brown dwarfs exist close to the Sun?

That's really cool. Brown dwarfs are neat.

Yeah. Some of them are actually as small as Jupiter.
