Brown dwarfs are sometimes called failed stars, since they form like stars through gravitational collapse, but never gain enough mass to ignite nuclear fusion. The smallest brown dwarfs can overlap in mass with giant planets. ...

Brown dwarfs are the cosmic equivalent of tweeners. They're too massive to be planets and too small to sustain nuclear fusion in their cores, which powers stars. Many brown dwarfs are nomadic. They do not orbit stars but ...

While we now know of thousands of exoplanets—planets around other stars—the vast majority of our knowledge is indirect. That is, scientists have not actually taken many pictures of exoplanets, and because of the limits ...

Brown dwarfs are known as "failed stars," owing to the lack of central hydrogen burning. They bridge the gap between planets and stars. Some brown dwarfs are found to maintain kilogauss magnetic fields and produce flaring ...
