Several gigantic gaseous planets have been spotted orbiting distant stars, but Planet Gliese 581 e could be the most Earth-like planet ever detected outside our Solar System. Located 20.5 light years away from us, it's 1.9 times the mass of Earth, indicating there are probably billions of Earth-sized planets revolving around stars throughout the universe.
The only problem with this planet is that it's so close to its star, it would be uninhabitable. However, three other planets revolve around that same star, and scientists say one of them, Gliese 581 d, could be covered by a large and deep ocean. It's situated far enough away from its star to be habitable. The catch with that one: it's seven times more massive than the earth, which would make human explorers feel awfully sluggish.

In conjunction with Australia’s National Science week, that country’s Canberra Deep Space Communication Complex, with NASA’s cooperation, will send 160 character, Twitter-like messages into space. Their target is Gliese 581-d, an exoplanet (one that orbits other stars) in the constellation Libra about 20.3 light years away from Earth.
