The first and most famous "failed star" discovered by humanity isn't one brown dwarf, but two! The duo comprising Gliese 229B are so tightly bound they orbit each other in 12 days.

With the help of the James Webb Space Telescope (JWST), a team of researchers has found the smallest brown dwarf we know of to date. And it's accompanied by two others, equally as mysterious. The ...

So the brown dwarf that three decades ago was named Gliese 229B is now recognized as Gliese 229Ba, with a mass 38 times greater than our solar system's largest planet Jupiter, and Gliese 229Bb ...

Brown dwarf binaries are thought to form like binary stars from the collapse of a massive cloud of gas to form two stellar bodies. In March 2024, using the Hubble Space Telescope, ...

Orbiting a star around 1,400 light-years away, astronomers have found a brown dwarf that is much hotter than any other measured, even exceeding the temperature of our own sun.

A group of astronomers found that a small, faint “brown dwarf” star is the coldest star yet recorded that still produces emission at radio wavelength. The findings were published last week in ...

The findings of the latest paper suggest that there may be many more brown dwarfs in the universe than previously thought, given that The Accident does not appear to resemble any of the roughly ...

The first brown dwarf, called Gliese 229B, was discovered in 1995, but its mass was inexplicably large, says Jerry Xuan at ...

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.

This brown dwarf is 67 times the mass of Jupiter and about the equivalent diameter. Because white dwarfs are small husks of former stars, WD 1202-024 is much smaller than its progenitor star.

The forming brown dwarf Mayrit 1701117 (bright orange-yellow) has a 0.7 light-year-long jet, shown in green emission from ionized sulfur in this image. Cesar Briceno And SOAR/NOAO/AURA/NSF ...
