A New World

Would you like to have a birthday party every 13 days? Then Gliese 581 c is the place for you!

Astronomers recently found the planet Gliese 581c. It orbits the star Gliese 581 once every 13 days. Earth orbits its star, the sun, every 365 days.

Gliese 581 c is an exo - planet – a planet that exists beyond our solar system. It is the most earth like exo - planet discovered so far.

Astronomers say there could be liquid water on Gliese 581 c. And where there’s water, there could be life. “Liquid water is critical to life as we know it,” says Xavier Delfosse, one of the scientists who discovered the planet. “This planet will most probably be a very important target of the future of space missions… On the treasure map of the universe, one would be tempted to mark this planet with an X,” says Delfosse.
