Astronomers using the Subaru Telescope in Hawaiʻi have discovered a massive planet and a brown dwarf orbiting distant stars.

Astronomers have discovered a batch of nine new brown dwarfs, also known as "failed stars," including the two smallest examples of these curious celestial objects ever seen. The new find could help ...

A pattern in the movements of a brown dwarf that orbits a Sun-like star is likely to be caused by a moon. If confirmed, this would be the first exomoon, that is a moon orbiting a planet that in turn ...

Astronomers believe they’ve discovered a "Tatooine"-like planet orbiting two stars in a galaxy far, far away. The planet is orbiting two brown dwarfs, which are also known as failed stars. It’s about ...

Two of the objects in the arrangement are cold brown dwarfs, which will serve as a benchmark for others throughout the Milky Way. By Katrina Miller Zenghua Zhang, an astronomer at Nanjing University ...

In a first, a pair of unusual stars has been revealed to have an equally unusual companion – an exoplanet that orbits them perpendicularly. Astronomers may think they know what is normal for stars and ...

"Dark matter could be captured by stars and accumulate inside them. If that happens, it might also interact with itself and annihilate, releasing energy that heats the star." "Dark dwarfs" may sound ...

A new "Tatooine-like" planet outside the solar system may orbit two failed stars, scientists reported Wednesday.Related video above: The dark energy pushing our universe apart may not be what it seems ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass ...

"The new brown dwarfs are the least massive known brown dwarfs. They place a new constraint on the lowest mass at which brown dwarfs exist." Astronomers have discovered a batch of nine new brown ...
