On this podcast episode, a planet hunter talks about our chances of finding alien life and other habitable worlds.

Jezero crater, the landing site for NASA's Mars 2020 rover, appears to harbor a mineral that could preserve signs of ancient life, researchers say.

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.

Gas from the upper reaches of the protoplanetary disk flows in to fill gaps that forming planets create near nearly formed stars, research finds.

Mars once had salt lakes, similar to some on Earth. Scientists now have an idea as to what happened to them.

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.

"This is a whole sequence of planets that can give us insight into the evolution of planets... It's just a gold mine."

A new "biosignature" for our own planet may help astronomers find exoplanets that could support life—or other worlds that already do.

The temperature on the nightsides of certain hot Jupiters is surprisingly uniform, research finds. This suggests clouds made of minerals.

Astronomers have discovered a new planet around a nearby star that is nine times the mass of Jupiter and more than 2,800 times the mass of Earth.
