A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than ...

NASA’s Transiting Exoplanet Survey Satellite (TESS) has been used to discover Earth-size planet TOI 700 e. It is "orbiting ...

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

Using HARPS and HARPS-N spectrographs, astronomers have observed a nearby K-type star designated HD 176986, known to host two ...

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

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 ...

The planet is one of the best worlds for follow-up studies to determine whether it could be habitable or not.

Worlds that circle stars other than our own are called “exoplanets.” This specific one could be the very first planet like Earth that we see passing in front ...

Astronomers have announced the discovery of what appears to be an "ice cold Earth," a chilly but potentially habitable rocky ...

Could a recently discovered "super-Earth" have the potential temperature and conditions to sustain life? The new exoplanet is situated "fairly close to us" -- only 137 light-years away -- and orbits ...

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 ...
