NASA says it has found proof that water shaped the rocks on the left, in a photograph taken by the Mars rover Curiosity (left). For comparison, the agency released an image of rocks from Earth (right).
NASA's newest Mars rover, Curiosity, has snapped photos of rocky outcroppings that jut out from the alien soil, and scientists say they look like the remnants of an ancient stream bed where water once flowed on the surface of the red planet.
The exposed rocks look like broken slabs of concrete sidewalk, about four inches thick, and are made of rounded bits of gravel in a sandy matrix. The rock has eroded a little bit, and some of the smooth pebbles — about the size of M&M candies — have fallen down into a little pile.

Aurora police officer Tim Jeffrey explains common procedures to a group of Bhutanese refugees. The police department organized the outreach event to help newcomers feel more at home.
Aurora, Colo., became a familiar name this summer, in the wake of a mass shooting at a local movie theater.
But there's much more to this Denver suburb than the recent tragedy. Just ask Ethiopian immigrant Fekade Balcha. Balcha's apartment, on Aurora's north side, sits in a dense neighborhood of squat brick apartment buildings and tiny homes.
"You see, in our apartment, there are Russians, Mexicans, Africans," Balcha says. "From Ethiopia, Somalia, Nigeria, and something like that."
