In photographs from Mars, traces of the movement of glaciers were noticed

International Group of Astronomers analyzed black-and-white images from the comic Mars Reconnaissance Orbiter (MRO) and came to the conclusion that they depict traces of the movement of glaciers.

It is believed that Mars once had a denser atmosphere and a huge amount of liquid water on the surface. This is evidenced by the beds of dried up rivers and lakes, which have repeatedly found scientists. However, about 4 billion years ago, the ice age began on the planet, which eventually turned it into the way we know it now - extremely cold and arid.

New photos prove this theory. Judging by them, on Mars, as well as on Earth, periods of sharp cooling and warming of the climate could alternate. Researchers note landforms that are very similar to the traces of the retreat of ice deposits in our interglacial periods.

It is known that on Earth glaciers are able to absorb stones with soil and transfer them both to their surface and under it. After melting, this material settles and creates a characteristic network of linear ridges. There are similar ridges in the published frames, which cover a vast territory about five kilometers long.

This once again proves that in the past Mars was warmer and wetter, and glaciers existed outside of its polar regions. True, on the planet, most likely, there was no precipitation and strong winds. The latter is evidenced by the absence of erosion in the discovered objects, the scientists conclude.
