Discovered, New Planet almost the same size as Earth
Just picked up this news about Earth size like planet out of the solar system. The newly discovered planet is known as Gliese 581. That’s the good news. The bad news is that it is so close to the parent star that, the surface of Gliese 581 is probably as scientist suspect , bombarded with harmful radiation.

Here is the full piece of news from NY times.
Astronomers Find Planet Closer to Size of Earth
European astronomers said Tuesday that they had discovered the smallest planet yet found orbiting another star. The planet could be as little as only 1.9 times as massive as the Earth and belongs to a dim red star known as Gliese 581, which lies about 20 light-years from Earth in the constellation Libra.
The star was already know to harbor at least three more massive planets. The new planet, known as Gliese 581e, is probably rocky like the Earth, but it lies in such a close orbit — only three million miles from its star — that it is surely blasted with too much radiation and heat to be livable.
