Possible Earth-Like Planet Found

Today astronomers announced they have discovered a planet outside of our solar system 120 trillion miles, or 20.5 light-years, away in the constellation Libra which appears to be earth-like. In fact it appears to have the right temperature and size/mass to hold onto liquid water, possibly even oceans:
"We have estimated that the mean temperature of this 'super-Earth' lies between 0 and 40 degrees Celsius, and water would thus be liquid."

"Moreover, its radius should be only 1.5 times the Earth's radius, and models predict that the planet should be either rocky - like our Earth - or covered with oceans."
The main difference is this planet is orbiting a red dwarf. But where there is water, and especially oceans there is a good chance there is life. Time and the BBC have good reviews.
