During the last weeks various rumors spread about possible amazing discoveries on Mars. Yesterday, NASA held a press conference to explain what was actually found by the Mars Rover Curiosity and at the moment there’s no evidence that on the red planet there are organic materials.

NASA’s Messenger (Mercury Surface, Space Environment, Geochemistry and Ranging) space probe has found new evidence of water ice in the polar regions of the planet Mercury, particularly on the floors of craters. The ice is covered by darker materials that may be organic compounds.
