We have heard a lot about exoplanets in the past year. But for all the talk about these planets, which orbit a star other than our sun, we still haven't actually seen one.

NASA released dramatic new findings from the planet-scouting Kepler spacecraft project Thursday. Looks like the universe is way, way more crowded than we had realized.

Someone call John Lithgow and pull French Stewart out of storage, a team of astronomers using the Kepler telescope have discovered the smallest exoplanets, in the tiniest solar system, so far. And their existence may show that our solar system isn't all that unique.

Astronomers have found two more new planets orbiting binary stars: Kepler-34b and Kepler-35b. Their discovery, which follow the original Tatooine discovery back in September 2011, is quite important: now we know there are millions of planets orbiting binary stars.

Answering to a We the People petition, the White House has officially replied to all those who wanted to know if aliens exists or if they have ever contacted us. The answer: no... but we're looking into it. Kind of.

What looks like a large burrito wrapped in tin foil, is designed to find habitable planets, and is sitting—inside a Delta II rocket—on Launch Pad 17-B at Cape Canaveral AFS, ready for launch tomorrow night?
