Brown dwarfs blur the lines between stars and planets. Brown dwarfs are curious celestial bodies that appear to straddle the mass divide between stars and planets. Often referred to as "failed ...

Brown dwarfs are lighter than stars, and heavier than gas giants like Jupiter. And while astronomers had measured the mass of Gliese 229B to be about 70 times that of Jupiter, an object of that ...

I say planet-like because brown dwarfs are not actually considered stars or planets. In fact, they straddle the line that divides planets and stars. They form similarly to other stars. However ...

But what exactly is this thing? It's not a comet or an asteroid. Scientists say it could be a low-mass star or a brown dwarf, ...

A diagram showing a brown dwarf in relation to Earth, Jupiter, a low-mass star and the sun. (Image credit: NASA) The brown dwarfs referenced by Parker are objects that form like stars, but during ...

The fastest-spinning white dwarf ever discovered is a shrinking cosmic vampire feasting on a stellar companion. A feeding ...

These cool, dim stars are known as brown dwarfs or 'failed stars.' But even the mass of a brown dwarf isn't enough to overcome the Coulomb barrier and start up stellar fusion. Fusion takes so much ...

Meet the brown dwarf: bigger than a planet, and smaller than a star. A category of its own, it’s one of the strangest objects in the universe. Brown dwarfs typically are defined to have masses ...

It consists of two stars that orbit each other: one is a white dwarf star — the hot, dense stellar core that remains after a low- or intermediate-mass star has exhausted its fuel, nearing the end of ...

The "generational talent" title is being handed out like lottery tickets. Too many buy in, while only a few hit big.
