A newly discovered exoplanet is rewriting the rules of what planets can be. Orbiting a city-sized neutron star, this Jupiter-mass world has a bizarre carbon-rich atmosphere filled with soot clouds and possibly diamonds at its core.

NASA’s Pandora mission will study exoplanet atmospheres by separating star light from planet signals, helping scientists learn which distant worlds may have air, water, and signs of life

A Congressional bill restores funding for most NASA space science missions, but there is no money for returning samples already collected on the red planet.

It's unlikely you'll be able to walk outside and see a line of planets, but according to NASA, a seven-planet parade happening tonight could be visible in some form in parts of the U.S. The upcoming cosmic event also follows a series of planets, like Mars ...

Relying on information from NASA's TESS telescope, astronomers Edward Bryant from the University of Warwick and Vincent Van Eylen from UCL compared stars in

NASA’s Hubble Space Telescope has captured infant planets colliding around Fomalhaut, one of the brightest stars in the night sky.

Astronomers tracking a nearby star system thought they had spotted an exoplanet reflecting light from its star. Then it vanished. Even stranger, another bright object appeared nearby. After studying years of Hubble Space Telescope data,

In doing so, they found this orphan is within the same weight class as Saturn, strengthening the case that the galaxy teems with castaway exoplanets — born within solar systems but chucked out later into the abyss, said Subo Dong, a professor of astronomy at Peking University in Beijing.

NASA has taken a bold step in the search for alien life beyond Earth. The space agency announced the selection of seven advanced technology partners for its next major mission, the Habitable Worlds Observatory.
