Scientists might have just found Earth's icy, distant cousin a few hundred million light-years away. HD 137010 b is one of ...

Astronomers may finally understand why planets orbiting two suns, the real-world equivalents of the "Star Wars" planet ...

New research suggests Einstein's general relativity explains the rarity of planets orbiting two suns. In tight binary systems, relativistic effects cause orbital resonances that destabilize planets, ...

Six planets are set to align on Saturday, creating a planetary parade that will be visible to sky-gazers across the globe.

Titan, the largest moon of Saturn, may have been even more instrumental to the system’s evolution than we thought, forming ...

I’ve yet to meet a physicist that didn’t believe in the beauty of the general theory of relativity—Einstein’s description of gravity as the curvature of spacetime. After all, it’s consistently ...

A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...

We are only a month into 2026, yet it’s already clear what one of the major space stories of the year is going to be: mega-constellations, and the ongoing attempts to launch thousands of satellites ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

The planets are visible throughout February, "but they’ll be lined up best toward the end of the month,” NASA says.

In the distant reaches of the solar system are many icy objects that resemble snowmen. Now, a new study reveals the simple ...
