Swirling Spirals On Mars' North Pole

Enlarge Image Sometimes old photos can provide new information. That's the case with a series of 32 images taken between 2004 and 2010 by the European Space Agency's Mars Express orbiter. The ESA released new mosaic images generated from those Mars Express pictures on Thursday, and they show a color view of Mars' strange north pole ice cap, a place full of exotic swirling formations. "Strong winds are thought to have played an important role in shaping the ice cap over time, blowing from the elevated center towards its lower edges and twisted by the same Coriolis force that causes hurricanes to spiral on Earth," the ESA notes.
