METEORITES / COMETS / ASTEROIDS

Sequence of Cratering on Venus using False Colour Image Processing



  Order of cratering not evident in the original black and white image



Shades of grey are assigned false colours and  indicate more than one cratering event



Additional false colours are added and the sequence of cratering is clear
