Created by David Makin using Ultra Fractal, 2009.  “This photograph was recently smuggled out of the NASA top secret files along with an analysis that states that this area of Mars definitely shows life but the green colouration is not down to chlorophyll, rather the life concerned appears to be equivalent to a green form of terrestrial fungus.  It also speculates that the growth is not native to Mars but originates from spores carried on vehicles from Earth.”
