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.

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.

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

New research finds that certain large exoplanets are shrinking due to internal processes, creating an abundance of rocky 'super-Earths'. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The air around ...

Talk about a hot mess. Scientists have uncovered a hellish “lava world” where temperatures soar to a blistering 2,700 degrees Fahrenheit — hot enough to melt rock into a churning ocean of magma and fill the air with the stench of rotten eggs.

Out of the 6,000 known exoplanets, it's these rocky worlds that are most worthy of attention in the search for life beyond our planet.

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,

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 ...

We may be missing alien radio signals because they have become smeared beyond the narrowband detectors that SETI utilizes, a new study suggests.
