Stephan Hawking once said "I don't think the human race will survive the next thousand years, unless we spread into space." I was really happy to hear about this news today when astronomers have found the most Earth-like planet outside our Solar System. The planet,
Gliese 581 c, orbits the faint star Gliese 581, which is 20.5 light-years away in the constellation Libra. It appears to be in the habitable zone of space surrounding the star, where the surface temperatures of any planets present might maintain liquid water and therefore be suitable for life as we know it.
