When astronomers search for exoplanets, they’re not only trying to confirm if they exist — but they’re also trying to see if they can support life as we know it. That’s because identifying exoplanets ...

When astronomers search for planets that could host liquid water on their surface, they start by looking at a star's habitable zone. Water is a key ingredient for life, and on a planet too close to ...

Exoplanet science is shifting from finding any detectable exoplanets we can to searching for those in their stars' habitable zones. NASA's proposed Habitable World Observatory and other similar ...

Hycean worlds are also called ocean worlds. They're planets covered in oceans that also have thick hydrogen atmospheres. There are no confirmed hycean worlds but many candidates. Even though they're ...

There is only one planet we know of, so far, that is drenched with life. That planet is Earth, as you may have guessed, and it has all the right conditions for critters to thrive on its surface. Do ...

The definition of a habitable zone was necessarily simple in the beginning. Any planet at the right distance from its star to allow liquid surface water was considered to be in the habitable zone. But ...

Astronomers have discovered a type of exoplanet called a “super-Earth” located in the habitable zone of its small star, and it’s right in our cosmic backyard, just 137 light-years away. The planet, ...

The planet, named TOI 700 e, is one of four known planets orbiting a cool star approximately 100 light-years away. The planet was discovered by NASA’s planet-hunting telescope, the Transiting ...
