The exoplanet Fomalhaut-b likely never was, say astronomers. Their work suggests an expanding cloud of dust instead.
"We don't only look at other planets to know what's out there. It's also a way for us to learn things about the planet that's under our own feet."
The Habitable-zone Planet Finder has confirmed the existence of an exoplanet that is likely close in size to Neptune, only 100 light years from Earth.
The proto-Earth formed surprisingly quickly, new research shows. The finding ups the chance of finding water and life on other planets.
Exoplanet NGTS-10b is either "in the last stages of its life, or somehow it's able to live here longer than it should."
Thanks to NASA's TESS spacecraft, scientists have discovered two amazing new worlds: A potentially habitable exoplanet and one with two suns.
Why there are so few exoplanets larger than Neptune has puzzled scientists, but new research offers a possible answer.
On this podcast episode, a planet hunter talks about our chances of finding alien life and other habitable worlds.
An out-of-place exoplanet seems to have escaped being destroyed when its parent star began to die. New research sheds light on how that happened.
The in-built uncertainty in science can be tricky for people who aren't researchers. Here, an expert explains how it applies in the search for exoplanets.
