Something is hiding inside Kepler-51d, and it’s doing a remarkably good job of it. About 2,615 light-years away in the ...

A small group of distant worlds may hold the clues to life beyond Earth. Astronomers searching for life beyond Earth have narrowed down the most promising places to look. Out of more than 6,000 known ...

Free-floating planets could host moons with tidal heating and thick, hydrogen-rich atmospheres that may be able to create billions of years of potentially habitable surface conditions.

The moons are all tiny, barely two miles across in size. When you purchase through links on our site, we may earn an ...

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 ...

Billions of years from now, the Sun will become a red giant. And then, it will slowly die. That’s right. It’s the end of the ...

Astronomers have identified a strange new kind of exoplanet that challenges how scientists classify worlds beyond our Solar System. The planet, L 98-59 d, appears to contain a vast ocean of molten ...

Discovered in the Pictor II dwarf galaxy, star PicII-503 has an extreme deficiency in iron—less than 1/40,000th of the sun. This signature makes it the clearest example of a star within a primordial ...

The planets of the Solar System are not representative of all the types of planets that exist elsewhere in the galaxy. There are worlds like hot Jupiters, gigantic and very hot, as well as ocean ...

Astronomers have discovered a bizarre exoplanet with a giant underground ocean of magma that traps sulphur and may represent an entirely new class of worlds.

A study led by the University of Oxford has identified a new type of planet beyond our solar system—one that stores large amounts of sulfur deep within a permanent ocean of magma. The findings have ...
