This free course, An introduction to exoplanets, introduces our galaxy's population of planets, and some of their many surprises. It explains the methods used...

A new space mission announced today (Nov. 16) will look for habitable planets in the Alpha Centauri system, our closest stellar neighbors.

Planets that orbit white dwarf stars should be too hot to host alien life, theories suggest. But a new study accounting for Einstein's general relativity may...

New lab experiments suggest that water may not be a rare visitor delivered by chance but rather a fundamental ingredient woven into the process of planetary...

Researchers can now measure the surface gravity of distant stars to help determine if the planets in their orbit have life-supporting conditions.

The controversial exoplanet Gliese 581g is the best candidate to host life beyond our own solar system, according to a new ranking of potentially habitable...

A new scientific model to understand the amount of our universe which is habitable developed by University of Aberdeen scientists is being announced today at...

Astronomy & Astrophysics (A&A) is an international journal which publishes papers on all aspects of astronomy and astrophysics

Astronomers have combined new observations of Gliese 667C with existing data to reveal a system with at least six planets. A record-breaking three of these...

Scientists should take the conservative approach when searching for habitable zones where life-sustaining planets might exist, according to James Kasting, Evan...

Scientists have discovered three potentially habitable super-Earths circling two different stars more than 1,000 light-years away. See what we know about them...

NASA scientists from across the agency will present their latest findings and perspectives on topics ranging from the origins and evolution of life on Earth

A new idea proposes that potentially habitable worlds can be split into four categories.

Our planet may be relatively low-rent

Many alien planets have strange, highly tilted orbits relative to their host stars. Scientists may have explained why: long-ago collisions with clouds of dust...

There is only one planet we know of, so far, that is drenched with life. That planet is Earth, and it has all the right conditions for critters to thrive on...

A new study that calculates the influence of cloud behavior on climate doubles the number of potentially habitable planets orbiting red dwarfs.

TOI-700 has not one, but two planets located in what scientists term the "habitable zone."
