The brown dwarf pair, called CWISE J014611.20-050850.0AB, are a mind-bending 12 billion miles apart — that’s more than three times the distance between Pluto and the sun.

An international team of astronomers has discovered the coldest brown dwarf star ever observed. ... CFBDS0059 might be the prototype of a new class of brown dwarfs to be called the Y dwarfs.

The brown dwarf is named CFBDS J005910.83-011401.3 (it will be called CFBDS0059 in the following). Its temperature is about 350° C and its mass about 15-30 times the mass of Jupiter, the largest ...

A team of astronomers has discovered a rare pair of brown dwarfs that has the widest separation of any brown dwarf binary system found to date. They're 12 billion miles apart, or three times the ...

Not to be outdone by the Keck II telescope in Hawaii, NASA's infrared Spitzer Space Telescope may have discovered a brown dwarf even cooler than the brown dwarf Discovery News reported on last week.

French and Canadian researchers have discovered the coldest brown dwarf star ever observed, a ball of gas about 15 to 30 times the size of Jupiter and with a temperature of about 660 degrees ...

But there's another class of object known as brown dwarfs. Instead of fusing hydrogen, they fuse something called deuterium, which is basically a hydrogen atom with an extra neutron.

In 1995, a parallel race was on in astronomy - one to find the first planet beyond our own solar system, and the other to find the first brown dwarf, a class of object too heavy to be a planet ...

The group observed the brown dwarf over a period of 10 hours at two different frequencies. In both cases, a bright flash was observed every 1.96 hours. As yet, the processes controlling the radio ...

The three brown dwarfs studied are roughly the size of Jupiter, but between 40 and 70 times more massive. (Image credit: NASA/JPL-Caltech) That absence suggests that either something is slowing ...

The first brown dwarf, called Gliese 229B, was discovered in 1995, but its mass was inexplicably large, says Jerry Xuan at the California Institute of Technology, who worked on one of the studies.
