NASA has revealed the very first peek at the sample collected by OSIRIS-REx — the space agency's first successful mission to collect a rock chunk from a distant asteroid.

But water wasn't the only material asteroids brought to Earth: The building blocks of life likely hitched a ride on a space rock, too. Bennu is a B-type asteroid, which means it contains high amounts of carbon and, potentially, many of the primordial molecules present when life emerged on Earth.
