The super-Earth likely contains an atmosphere ...

Astronomers caught helium escaping the habitable-zone world LHS 1140 b — a signal that strengthens the case for the planet's ...

Scientists have discovered a rocky planet that is likely to have an atmosphere — and could be a host for life. “It’s been a major goal in the field of exoplanets to find atmospheres on rocky ...

A rocky exoplanet 48 light-years from Earth has offered the 'strongest evidence yet' that other planets besides Earth could ...

For the first time, astronomers have detected an atmosphere on a rocky, temperate world beyond our solar system. It is the strongest evidence yet for an exoplanet that could be able to support alien ...

In this artist’s concept, the exoplanet LHS 1140b is shown in the foreground, surrounded by a helium-rich atmosphere. Another nearby rocky planet orbits the same cool red dwarf star in the ...

NASA has discovered an exoplanet so unusual that it almost looks too perfect to be real. Its size, orbit, and possible conditions have raised questions about whether worlds like Earth may be far more ...

July 15 (UPI) --A team of astronomers found a new exoplanet -- the faintest ever imaged from the ground -- hiding in plain sight in images that date back at least 11 years, a study released Wednesday ...

The object orbits a brown dwarf that orbits a star, and astronomers aren’t sure if it’s a planet, a moon — or something else ...

Ever so slightly bigger than Earth, the exoplanet LHS 3844b orbits its parent star, LHS 3844, a red dwarf 48.5 light-years from our solar system. Its rotational speed mirrors its orbital speed. The ...

For the first time, astronomers have detected an atmosphere around a rocky planet orbiting in the habitable zone of a nearby star. Such planets have long been considered the best places in the galaxy ...
