The European Space Agency (ESA) has released a new image of the surface of Mars, which shows a unique structure. It is a so-called "scar" called Aganippe Fossa.
The image shows a dark, uneven "scar" that pierces the marble surface at the foot of a giant Martian volcano called Mount Arsia.
Aganippe Fossa is about 600 km long. For comparison, the distance from Chernihiv to Odesa by road is 610 km. So you can imagine how long this "scar" is on Mars.
Structures such as Aganippe Fossa are called "grabens" - areas with steep cliffs on both sides. The new image was taken by the Mars Express spacecraft.
The ESA says they still don't know exactly how the "scar" appeared on the Red Planet. But they assume that it happened during a colossal volcanic eruption.
ESA specialists also managed to record two different types of terrain. One consists of many irregularly shaped hills and valleys. The other is a relief formed by gentle cliffs and rocky debris.
