Gliese 581: the mother star. Gliese 581 is a red dwarf located 20.5 light-years from Earth, in the constellation Libra. Like other red dwarfs, it's smaller and much dimmer than our sun.

In over a million years, the star Gliese 710 will reach the edge of our Solar System, disturbing comets in the Oort Cloud. That could be bad news for Earth.

The first and most famous "failed star" discovered by humanity isn't one brown dwarf, but two! The duo comprising Gliese 229B are so tightly bound they orbit each other in 12 days.

A rocky alien planet called Gliese 581d may be the first known world beyond Earth capable of supporting life as we know it, a new study suggests.

Gliese 581 is a red dwarf star a mere 20 light years way; it’s one of the closest stars in the sky to us. Two different teams of astronomers, one Swiss and one American, ...

Where there's water, there's the possibility of life. It just so happens that H2O acts as an ideal medium for chemical reactions between organic molecules, helping them link together to form amino ...

Gliese 667Cc's parent star is part of a triple-star system, so the planet's night sky would probably be a sight to behold. Kepler-22b. Kepler-22b was spotted by NASA's planet-hunting Kepler space ...

The star could catapult asteroids into our solar system. Skeeze / Pixabay Researchers have known for a while that a star called Gliese 710 is headed straight for our solar system, but they've now ...

Gliese 667C is a very well-studied star. Just over one third of the mass of the Sun, it is part of a triple star system known as Gliese 667 (also referred to as GJ 667), 22 light-years away in the ...

The exoplanet Gliese 12 b is tantalizingly close and moderately warm, situated just 40 light-years away around a red dwarf star. The potentially habitable planet could be a good place to search ...

The star, called Gliese 710, is headed for a close encounter with our Solar System, and we know that thanks to the ESA’s work on what it calls the Gaia Mission.

Some 22 light years away, a short hop by galactic standards, six planets, and maybe a seventh, orbit the star Gliese 667C. Three of these planets orbit within the star’s narrow habitable zone ...
