Astronomers see second Earth in the making

This could give alot of clues to our own Earth's formation.
And its good to know that theres a possibility of life taking hold in the universe,in the future.

(MSNBC)-Astronomers have spotted evidence of a second Earth being built around a distant star 424 light-years away.
Using NASA's Spitzer Space Telescope, astronomers have spotted a huge belt of warm dust swirling around a young star called HD 113766 that is just slightly larger than our sun. The dust belt, which scientists suspect is clumping together to form planets, is located in the middle of the star system's terrestrial habitable zone where temperatures are moderate enough to sustain liquid water. Scientists estimate there is enough material in the belt to form a Mars-sized world or larger.

Interesting. Hopefully "habitable" planets like these will be formed
in time for humanity to go there when the sun expands!
