NASA has announced the discovery of an Earth-like planet orbiting a Sun-like star that shares several other similarities with ...

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

A unique characteristic of the candidate planet HD 137010b is its ice-cold temperature.

A newly identified Earth-sized exoplanet with a year-long orbit may lie near its star’s habitable zone, but extreme cold could limit its chances of hosting liquid water.

Alexander Venner picked his way by hand through the data collected by a now-retired NASA telescope called Kepler, which ...

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 ...

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

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 ...

A new discovery in the search for Earth-like exoplanets has just been published in The Astrophysical Journal Letters on ...

If confirmed, this exoplanet would be the only known rocky world in the habitable zone of a Sun-like star.

A distant flicker of light from a star can reveal more than you might expect. In fact, a brief, subtle brightening in the sky has helped scientists uncover something astonishing: planets much like ...
