New Rings Found on Mars. New ring formations have been examined by Matt Blume and colleagues. The circles are made of stone and are prompting scientists to rethink Mar's climate history. Blume and others have mapped a new area on Mars where the rings where found that is near the equator, naming the region Elysium Planitia. Blume used the Mar's Reconnaissance Orbiter to take pictures of the area. Similar stone rings are found on Earth. The rings on earth are formed by repeated freezing and thawing of ice with stones in between that are stored in the layers. The structures on Mars where formed by freezing and thawing of water but the type of stones are unclear. Liquid water should be near the surface of these rings. This means that Mar's climate could be 40-60 degrees warmer than thought before.
