Just as we usually associate scars with traumatic events from the past, in this case there was a lot going on. According to scientists who study what happened on the Red Planet in the past, such a formation may be the remains of a huge lake of magma associated with a volcano millions of years ago.

Representatives of the European Space Agency spoke about this. As they explain, the formation shown in the images is My songs are fosaIt was first observed in 1930, although it only received its official name 46 years later. We are talking about a structure about 600 kilometers long. This is an impressive size, although it is still far from the largest valley in the entire solar system.
This is the name given to another Martian body, Valles Marineris. The images showing Aganippe Fossa were taken on December 13 of last year. What is striking is the varied landscape on either side of the valley. On one side you can see uneven terrain covered with numerous hills and depressions. On the other, notice any contrasts. However, there are stripes that the researchers compare to the stripes of a zebra.
The structure observed on the surface of Mars is called a scar by scientists. Its presence may be linked to ancient volcanic activity.
The entire formation lies within an ancient volcano known as Arsia Mons. The 20-kilometre-high object is located a short distance from the largest volcano in the solar system, the 25-kilometre-high Olympus Mons. The differences in the landscape divided into the left and right sides of the valley appear to be the result of wind erosion that has occurred over millions of years.

The title scar appears to have been caused by magma building up beneath the surface. This is what pushed the rocks upward, creating Mons Arsia. Unfortunately, researchers cannot assess when this formation was created. Complicating matters is the fact that Martian volcanoes have a very unclear framework. According to some theories, it stopped millions of years ago, while others suggest it dates back only 50,000 years.
