Scientists have discovered thousands of hills and mounds on Mars, consisting of layers of clay minerals, which were formed during the interaction of current water with rocks when an ancient ocean was in the north of Mars. A new study shows that in the distant past, the climate on Mars was completely different, and a large amount of liquid water was on the surface of the Red Planet almost 4 billion years ago. The results of the study are published in the journal Nature Geoscience, writes Space.

The two hemispheres of Mars are different from each other. Ancient hills are located in the south, and in the north - the low -powered plains changed by erosion, where, as scientists believe in the distant past, the ocean was located. Now there is a lot of evidence that Mars was much warmer and there were rivers, lakes, seas and even oceans about 4 billion years ago.

Now, scientists have discovered new evidence that there was an ocean in the north of Mars and they are associated with the detection of more than 15,000 hills and mounds up to 500 meters high, which contain clay minerals.

On Earth, such features of the relief in the form of hills and dining mountains can be found in deserted regions where rock formations have been subjected to erosion by the wind for millions of years. Scientists also found something on Mars using the data of the Mars Reconnaissance Orbiter, Mars Express and Trace Gas Orbiter orbital devices..

Scientists believe that thousands of hills and mounds are all that remains of a hill that retreated hundreds of kilometers and was blurred by water and wind in a vast low area called the plain of Chrys.

Scientists have found that the mounds on Mars consist of layers of clay minerals that form when liquid water interacts with a rock for millions of years. Scientists suggest that there was a huge pond on the surface of Mars, possibly the Northern Ocean.

Under and above layers of clay, scientists discovered more old and younger rocks, respectively, which do not contain clay. Scientists believe that clay minerals belong to the period of the history of Mars, when the planet was liquid water on the surface, namely between 4.2 and 3.7 billion years ago.

According to the authors of the study, the Rosalind Franklin Mars -Road, which should go to Mars in 2028, should land in this region..

This peremrel will help to say exactly, was on Mars Ocean, and if it existed, if an extraterrestrial life could exist there.

Focus also wrote that the Curiosity Mars -Road found the remnants of the ancient lake on Mars, which also indicates that billions of years ago on the Red Planet, water was in a liquid form on the surface.

As Focus already wrote, a boson star, which is directly related to dark matter, can be next to us. Scientists believe that the Universe can be filled with unusual boson stars or dark stars.
