NASA's Curiosity rover is currently exploring the base of Mount Sharp. The Martian peak's base has features similar to Recurring Slope Lineae (RSL), which are caused by liquid water, but none are confirmed to be RSL. Sites 33, 36, 46, and 56 are closest to the rover. <br />
NASA announced today that it has discovered the first "circumbinary planet"--a planet orbiting two stars. While the planet's officially called Kepler 16b, astronomers are already referring to it as Tatooine, after the home planet of Luke Skywalker in the Star Wars movies, which also had two suns.
So amazing! A dune field on Mars in the north, less than 400 km from the north pole. During the Martian winter, carbon dioxide freezes out of the air. In the summer the CO2 turns directly from a solid to a gas disturbing the sand which falls down the slopes in little channels spreading out when it hits the bottom. This disturbs the red dust, which flows with the sand creating the feathery tendrils seen here
