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 ...

Running the spectra through models, Coelho and her collaborators determined that exoplanet clouds with the colorful microorganisms would look different from exoplanet clouds witho ...

An illustration shows what exoplanet K2-18b might look like based on data from NASA's James Webb Space Telescope. K2-18b is 8.6 times as massive as Earth, orbits the cool dwarf star K2-18 in the ...

No planets cooler than about 35.33 degrees Fahrenheit had ever been detected. An exoplanet discovered in 2020 contains the coldest temperatures ever measured on a planetary body, according to ...

Our search for exoplanets is focused on Milky Way stars. It's been successful, with more than 6,000 detected so far.

Exoplanets are planets outside Earth's solar system that most often orbit a star. Astronomers have managed to bring an exoplanet into unprecedented focus by using a technique the researchers call 3D ...

A nearby binary star system is bereft of giant planets, but scientists think it may still be a decent place to look for life.

What happens when a planet contains immense quantities of water but is far too hot for that water to remain liquid?

Astronomers have identified thousands of exoplanets, but only a handful look like Earth. These 16 worlds may be the closest thing to a second home ...

An alien world near Earth is being trailed by a gigantic tail, stretching longer than 40 Earths as it closely circles its home star. The enormous structure, which is made up of gas leaking from the ...

Join astronomers Franck Marchis (SETI Institute) and Julien Girard (Space Telescope Science Institute) for a 30-minute live discussion unpacking NASA’s exciting new findings from JWST. Just announced, ...
