It's remarkably similar to Earth.

Astronomers have identified a newly discovered exoplanet that may orbit within the outer edge of its star's habitable zone, ...

Scientists may need to broaden their horizons in their search for alien life.

This artist’s concept shows the volatile red dwarf star TRAPPIST-1 and its four most closely orbiting planets, all of which have been observed by NASA’s James Webb Space Telescope (JWST). JWST has ...

Finding life elsewhere in the cosmos is no easy task. We’ve been searching for decades and, so far, we haven’t heard from anyone and we haven’t found anywhere that looks quite like home. While ...

Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, if more detailed analyses verify preliminary observations from the James Webb ...

Scientists studying the rocky exoplanet TRAPPIST-1e may have found hints of an atmosphere. If confirmed, it could be an important step toward finding a habitable world outside our solar system. When ...

One of the main questions in exoplanet science concerns M dwarfs (red dwarfs) and the habitability of exoplanets that orbit them. These stars are known for their prolific and energetic flaring, and ...

A NASA mission has spotted an Earth-size exoplanet orbiting a small star about 100 light-years away. The planet, named TOI 700 e, is likely rocky and 95% the size of our world. The celestial body is ...

At the beginning of the exoplanet age, the goals were fairly simple. The first was to find as many of them as possible to flesh out our understanding of the exoplanet population. The second was to ...

If we’ll ever find life outside our solar system, it will not be an instant discovery. Save for the slim possibility of an intelligent civilization beaming a message in our direction, evidence for ...
