Here it is, Kepler 452b, our larger, older cousin, 60% larger than ours, with double our gravity, and estimated to be 6 million years old. This planet would show a lot about our own world as it continues to evolve. Settled well in its habitable zone, this planet (believed to be rocky in composition) is a great candidate for life. Having had more time for evolution to work, this planet's life could be quite complex. This is very exciting news and NASA now believes the number of potential earth-like planets in our own galaxy is huge.
Fire up the warp drive, jump to hyperspace, we've got places to explore, to boldly go, seeking out new life and new civilizations.
