Here Is What Mars Would Look Like With Oceans.

They might look like trees on Mars, but they're not. Groups of dark brown streaks have been photographed by the Mars Reconnaissance Orbiter on melting pinkish sand dunes covered with light frost. The above image was taken in 2008 April near the North Pole of Mars. At that time, dark sand on the interior of Martian sand dunes became more and more visible as the spring Sun melted the lighter carbon dioxide ice. When occurring near the top of a dune, dark sand may cascade down the dune leaving dark surface streaks.

This illustration shows an alien planet named OGLE-2007-BLG-349 orbiting a pair of red dwarf stars. It was originally thought that the exoplanet may only have one sun according to astronomers. However, the Hubble Space Telescope has found a second star.

As we look back into the history of our landscape, a much older history lies above us.

Once upon a time, Mars had lakes, or at least wetter conditions than it does today. The latest from NASA’s Curiosity Mars rover shows slabs of rock cross-hatched with shallow ridges that likely originated as cracks in drying mud, evidence of an ancient era when these sediments were deposited were.

A fiery sunset seen by an astronaut aboard the International Space Station looks toward the South Atlantic. With Earth’s surface already in darkness, the setting sun, the cloud masses and the sideways viewing angle make a powerful image.
