Life on Earth is a precious thing, especially given what astronomers know about the visible universe. Although researchers have so far identified over 6,000 exoplanets beyond our solar system, only a handful of them may be suitable for human visitors.

The molten exoplanet, larger than sub-Neptune, could be a new class of planet.

The molten planet, with an atmosphere rich in sulfur-bearing gases, is unlike anything astronomers have ever smelled.

A new study shows that stars with low magnetic activity are likely to support exoplanetary systems, making the hunt for these celestial objects less random.

Alien solar systems that are home to so-called "hot Jupiters" — gas giants circling sizzlingly close to their stars — are unlikely homes for Earth-like planets, researchers say. Hot Jupiters get their name from the fact that they are approximately ...

Astronomers have discovered a strange new world just 35 light-years from Earth – one permanently covered in a vast ocean of molten rock. The exoplanet, known as L 98-59 d, defies existing models of planetary formation and may represent an entirely new class of planet,

A warehouse worker, Teddy (played by Jesse Plemons), accuses high-powered CEO Michelle (Emma Stone) of being an extraterrestrial who is secretly killing bees, disrupting the ecosystems humans depend

By Will Dunham WASHINGTON, March 16 (Reuters) - Astronomers have spotted a planet orbiting a star in our neighborhood of the Milky Way galaxy that presents a unique hellscape - covered with a perpetual ocean of magma and enveloped by a noxious and fiercely hot sulfur-rich atmosphere.

Scientists have identified 45 Earth-like exoplanets that are the strongest known candidates for hosting extraterrestrial life.

SCIENTISTS have uncovered an absolute stinker 34 light-years from Earth. A newly discovered planet, called L 98-59 d, is among the stinkiest ever with a strong rank stench worse than rotten egg
