What if humanity could no longer live on Earth? Perhaps a catastrophic event forced us to find a new home among the stars.

Only 11.4 light-years away, two exoplanets have been detected around a neighboring star. One of them, Gl725Bc, is located in ...

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 ...

An international team of scientists, including researchers at Penn State, dubbed the exoplanet, named GJ 251 c, a “super-Earth” as data suggest it has a rocky composition similar to Earth and is ...

Located about 39 light-years from Earth, the TRAPPIST system resembles a miniature version of our solar system: The star, an ultracool red dwarf, and all its planets would comfortably fit inside the ...

An exoplanet called HD 137010 b might be the closest thing astronomers have ever seen to “Earth 2.0.” The trouble is that it’s only been seen once—and may never be glimpsed again ...

Learn about HD 137010 b, a cold Earth‑sized planet candidate that sits near the outer edge of its star’s habitable zone.

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 ...
