HD 137010 b is an Earth-size planet candidate with a 355-day orbit around a nearby star, making it a top follow-up target.

Astrological drama alert!

Brown dwarfs are the weird middle-ground of space - not a planet, but not a real star either. They’re massive enough to “smolder,” but not powerful enough to fully ignite like the stars we’re used to.

At least two students were killed, and nine other students were wounded in a mass shooting Saturday at Brown University in Rhode Island. School officials confirmed the shooting took place at about 4 p ...

In our Milky Way galaxy, the most common type of star is the small, cool star known as an M dwarf, or red dwarf. They make up more than half of all the stars in our galaxy. Because M dwarfs are ...

When astronomers pointed the James Webb Space Telescope (JWST) at a faint object orbiting a distant star system, they weren’t expecting to find one of the universe’s strangest chemical ...

Astronomers were astonished to find an abundance of phosphine, a molecule produced by microbes on Earth, in the atmosphere of a brown dwarf, an unusual type of object that lives in the grey zone ...

An illustration of the Wolf 1130ABC triple system, which is composed of a red dwarf star (left), a white dwarf (center) and the brown dwarf where phosphine was detected (right). Adam Burgasser For the ...

Brown dwarfs: too small to be stars, too big to be planets. Only discovered in the 1990s, these in-between cosmic objects aren’t big enough to burn as hot and bright as a true star, instead usually ...

The detection of the molecule phosphine in a brown dwarf’s atmosphere may help astronomers in their search for life elsewhere in the Milky Way. By Katrina Miller On a brown dwarf dozens of light years ...

An orange, striated sphere hangs in space with stars behind it with a line from it drawn to a box that contains a space-filling model of phosphine where phosphorus is orange and hydrogen is white.
