The natural world. Looking pretty for 3.5b years.

Blue Dunes...Who Knew?

Author: Hugh Bollinger/Monday, October 14, 2013/Categories: natural history, photography, space science, environment

Because we don't see in the infrared, we aren't able to see the array of colors that exist in the natural world. If we could, we could see that sand dunes on Mars are blue. Luckily, the HiRISE orbiter circling Mars can do what we can't. Besides appearing blue, they are also very beautiful as well. This photograph was captured while the satellite passed over a region known as Noachis Terra.
