So what do you think this is? Pigskin? Close-up of chicken feet? Microphotograph of cells from inside of your mouth?
This is actually a NASA picture from Mars. It was taken in 2008 and it is on the floor of Ius Chasma, the largest canyon in the solar system. This landform (or Mars-form) was created by a process called sapping where water would seep from the cliffs and creep down, but evaporate before reaching the canyon floor.
Amazing shot. Mars would be a fascinating place, but according to Elton John in Rocket Man, it ain't the kind of place to raise your kids.
