Scientists believe the exoplanet HD 20794 d, six times the mass of Earth, could harbour liquid water on its surface.

A rocky planet less than half the mass of Earth seems to have an atmosphere made almost entirely of sulphur dioxide – this ...

New research points toward an exoplanet that may be capable of supporting life 20 light-years away from Earth.

UK researchers have confirmed the existence of a “super Earth” located 20 light-years away that could reveal the existence of extraterrestrial beings.

The system is believed to be traveling at least 1.2 million miles per hour (1.93 million kilometers per hour), according to a ...

But scientists have found planets way beyond our own solar system. Known as exoplanets, these make Neptune seem close indeed. The closest exoplanet – called Proxima Centauri b – is four light years ...

How would detecting methane help astronomers identify if exoplanets, or even exomoons, have life as we know it, or even as we ...

Here are some pics of most earth-like exoplanets uploaded by NASA: Gliese 667Cc, 22 light-years from Earth, is 4.5 times Earth's mass, orbits its cooler red dwarf star in 28 days, and likely resides ...

An international team has confirmed the discovery of a super-Earth orbiting in the habitable zone of a nearby sun-like star.

Astronomers who identified HD 20794 d say its proximity to its host star and orbital pattern suggest it could hold water.

Scientists have discovered a ‘super-Earth’ planet six times larger than our own which may have conditions suitable for life. The exoplanet – a planet outside our solar system – was spotted by Oxford ...

An exoplanet about 800 light-years away is spilling its guts into space, and new observations with the James Webb Space Telescope, or JWST, have let astronomers read the entrails, astronomers report ...
