The planetary system, located 120 light-years away, features four worlds orbiting a red dwarf star and challenges classical formation schemes.

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

A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...

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.

Planets are often described as ancient, unchanging worlds. Planets are born out of chaos, shaped by violent collisions and ...

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

Astronomers are closing in on what looks like a rare prize: a world almost the size of Earth, circling a Sun-like star at a distance that gives it a familiar, year-long orbit. The candidate, known as ...

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

A faint signal from old telescope data is causing a stir in astronomy: a planet barely larger than Earth, with an almost identical orbital period, and a star astonishingly similar to our sun. It is ...

Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than ...

WASHINGTON - European astronomers say that just outside our solar system they've found a planet that's the closest you can get to Earth in location and size. It is the type of planet they've been ...
