On October 9, 2008, the State Space Agency of Ukraine sent a message towards Gliese 581c. Unlike the Voyager records, whose messages were chosen by a committee chaired by renowned physicist Carl Sagan ...

From being the most Earth-like planet known to being consigned to the trash bin, the story of Gliese 581g is a precautionary tale for exoplanet hunters.

Even as some astronomers start shoveling dirt on the much-heralded "first potentially habitable" alien world – a planet called Gliese 581g – its co-discoverer is vigorously defending the find ...

NASA says Gliese 12 b could help researchers understand the habitability of other planets across the galaxy.

Both teams found that, while Gliese 581 c is too close to the star to be habitable, the planet Gliese 581 d might be habitable.

Gliese 12 b is the nearest transiting temperate Earth-sized planet that we found to date. And this was actually, it was a long process for discovering this planet.

Newly-discovered exoplanet Gliese 12 b has the potential to support human life, per a study outlined in the "Monthly Notices of the Royal Astronomical Society." ...

The discovery of Gliese 12 b, a nearby possibly habitable exoplanet, is a thrilling development in the quest to find Earth-like planets and, potentially, extraterrestrial life.

Both teams found that, while Gliese 581 c is too close to the star to be habitable, the planet Gliese 581 d might be habitable. However, the environmental conditions on planet d might be too harsh ...

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.

If Gliese 12 b’s potential atmosphere is like Venus, it is an entirely different story. The planet has a runaway greenhouse effect that has made it a 752°F hellscape.
