Found: The Holy Grail of Planetary Science

Found: The Holy Grail of Planetary Science

"Recently, a nearby earth-like twin was found in outer space—perhaps capable of harboring life. The planet is called Gliese 581g, and is 20 light years from Earth (about 120 trillion miles). In width, it is about 20% to 30% or so bigger than the Earth, but weighs about 3 to 4 times more. What is exciting is that the planet is inside the Goldilocks zone—meaning it is not too close to its sun (where water would boil) or too far (where water would turn to ice), but just right to have liquid water, one of the most precious substances in the Universe."

This is incredible news. It's the first hard evidence that there really could be life out there. That the possibility isn't just speculation.

I am excited about this
