New photographs of ‘Martian mushrooms’ have left some scientists convinced that there is life on the Red Planet. A new study published in the Journal of Astrobiology builds upon 15 images captured by NASA’s Curiosity Rover.

As part of its two-year mission, Curiosity trained its camera on what appears to be algae, lichen and mushrooms. The photos seem to show the potential life forms growing larger and emerging from the red sands of Mars.
