Exoplanet news, features and articles

Two Earth-like exoplanets appear to have smashed into each other in a distant solar system, and the cosmic carnage is only getting worse.

The 1995 discovery showed that the sun isn't the only star to host a family of planets — something we had long figured but never demonstrated — and also that the universe is really, really weird.

Here's the reality: We're messing up the Earth and any far-out ideas of colonizing another orb when we're done with our own are wishful thinking.

This first-of-its-kind discovery reveals a new category of ultrahot exoplanet, one so thoroughly cooked that your cast-iron skillet would bubble, turn to gas and boil out of the atmosphere.

NASA's new exoplanet-hunting telescope has discovered its smallest planet yet: a world somewhere between the sizes of Earth and its smaller sister, Mars.

NASA scientists cooked up an alien atmosphere in their lab to solve the puzzle of "hot Jupiters."

There's a rocky planet in our stellar neighborhood that's very big and cold. However, scientists argue, it might still hold life.

Scientists think there's a giant new planet full of frozen water, and it's right down the cosmic street from Earth.

There's a telescope that can see thick rings of dust in distant star systems. And researchers want to use its data in a new way to spot hidden and migrating exoplanets.

A global, liquid-water ocean could exist under range of conditions on Proxima Centauri b, the closest known exoplanet to Earth.
