Some 225 million kilometres away, the Mars Curiosity Rover is trundling about the surface of the Martian planet, investigating rocks, soils and taking a bunch of incredible photos.

Take Scott C Waring, editor of UFO Sightings Daily. He's just got very excited about an image that French UFO hunter Christian Mace has brought to his attention.
