You know the trippiest thing about space? It just goes on forever, man! And there's so much out there! Like the two new planets that NASA just discovered, hanging out 1000 light-years outside of our solar system, looking suspiciously similar in size to our very own Earth.

The two planets, dubbed Kepler-20e and Kepler-20f, are orbiting around a star similar to our sun. Since they're so close to their own gaseous sun-star, the Keplers are too hot to harbor life, but they're still freaking awesome! "This is a most important milestone," said Francois Fressin, the lead author of the paper describing the planets. "It demonstrates for the first time that Earth-sized planets exist around other stars, and secondly that we are now able to detect them."

On top of that, the Keplers are blowing scientist's minds because they prove that there's more than one way to form a solar system. Ours, for example, features larger and more gaseous planets further away from the sun, but Kepler-20's system features five planets of alternating size. "Now we're realizing that there's a larger variety of solar systems out there," said Jason Rowe, a research scientist with NASA.

And while these little guys are exciting in their own right, the world eagerly awaits the moment when we find liquid water on another planet, setting the stage for the ultimate close encounter. "In the cosmic game of hide and seek, finding planets with just the right size and just the right temperature seems only a matter of time," said Natalie Batalha, Kepler deputy science team lead. "We are on the edge of our seats knowing that Kepler's most anticipated discoveries are still to come."
