He may have been a little quirky, but mathematician Albert Einstein was a really, really smart dude. And now, thanks to some long-lost posthumous photos of his brain, scientists think they've figured out why he was so bright.
Jupiter is a big planet. We live on a big planet, but Jupiter has 121.9 times the surface area of Earth. Jupiter is so big, in fact, that it's actually 2.5 times more massive than the rest of the planets in our solar system combined. Imagine that, now multiply it 13 times, and you've got a new planet that makes Jupiter look small.
It's an enduring puzzle that's had astronomers and astrophysicists scratching their heads for years: Why does the Earth tilt? Our planet orbits with at slight (7-degree) angle relative to the Sun, and we've never been able to figure out why, but now one scientist thinks he's got our planet's crooked spin solved.
Though they vary widely in other characteristics, we usually think of planets as having one unifying quality: they're all orbiting a star, right? Well ... apparently not. It seems there could be quite a few "orphan" worlds just floating out in space, and scientists think they just found one really close to Earth.

Like us, stars lose some energy and fade a bit as they age (at least until they explode), but one star, at the ripe old age of 40 million, has baffled scientists for two decades with its amazingly youthful appearance. Now, scientists think they've figured out the secret to the star's vitality.
A 1909 report on the brain of famed mathematician Charles Babbage has surfaced on the public domain, showing off some surreal shots of the late genius' mind.
It was the biggest living thing to ever take to the skies, a dinosaur the size of an F-16 fighter with a 34-foot wingspan and a weight of 155 pounds. Despite its size, it managed to get off the ground without the aid of mountains or cliffs, but how? Scientists now think they know, and the answer, like the dino, is a bit jet-like.
A few months ago, scientists predicted that it would take two more years until we found another habitable planet somewhere out there. Well, one team of astronomers may have just shattered that prediction, because the planet they just found looks very promising and very Earth-like.
An asteroid's hurling toward the planet. So what do we do? Do we fire nuclear missiles at it? Do we send a team up on a special space shuttle to drill down into it? Or do we do something you'd probably never see in a movie? According to a new theory by an MIT grad student, our best hope to save Earth from a deadly asteroid could be ... paint?
