Astronomers have for the first time discovered a planet which originated outside our galaxy.

'Habitable exoplanet' may not exist, says Geneva team

Oh, great. The moving men were booked, we'd said goodbye to the neighbors and we'd given away the cat - and now it seems that there may not be a habitable planet orbiting Gliese 581 after all.

First truly habitable exoplanet found

Astronomers believe they may have found a habitable planet at last, in the widely-studied Gliese 581 system 20 light years away in the constellation of Libra.

Habitable exoplanet could be identified next year

The odds are that a habitable exoplanet will be found by the middle of next year if the rate of discovery continues at its current pace, two scientists say.

Supersonic winds observed on exoplanet

Astronomers have for the first time observed a massive storm on a planet outside our solar system.
