A new study published by the US space agency NASA reveals that Mars has previously had thousands of super-volcanic eruptions that probably affected the entire planet's atmosphere. The area where these mighty volcanoes are located is located in the northern part of the planet called Arabia Terra.
The area has what looks like many round craters and in the past it was thought that these were remnants of asteroid impact on Mars.
However, a previous research team published in 2013 the hypothesis that these were volcanic craters that collapsed after a huge eruption.
The reason for the hypothesis was that in contrast to an entire circle formed after an asteroid impact, the circles in the Ozer Terra Arabia look like missing circles formed after the collapse of a volcano following a super eruption.
In such a case the huge amount of trend that comes out leaves a huge space to which the mountain collapses.
This is often a collapse on the order of tens of kilometers that does not always look symmetrical.
This hypothesis was tested by NASA researchers who estimated that if there were such huge eruptions then remnants of the eruption would be found on the planet in the form of volcanic ash thrown into huge ranges.

Evidence has been found that a region of northern Mars has experienced thousands of "super eruptions," blasting the equivalent of 400 million Olympic-sized swimming pools of molten rock & gas, over 500-million years.

To test this hypothesis, the researchers consulted Alexandra Mathieu Novak, a volcanologist specializing in the Johns Hopkins University Applied Laboratory, who calculated how far such volcanic ash would fly and where to look for it on the planet.
According to NASA volcano man Patrick Willie, “Our research showed that four billion years ago and for 500 million years thousands of super-oil eruptions erupted on the planet that probably dramatically affected its atmosphere and the arrival of sunlight and possibly even its temperatures.

We checked the depth of the ash layer that was formed and we actually got thousands of eruptions when the material emitted in each such event was equal to 400 million Olympic swimming pools. "Alexandra Novak adds:" .
In fact in those five hundred million years, the thousands of tremendous eruptions on the planet have dramatically affected it and changed its atmosphere and its entire environment. But now it is possible to find out why on Mars all these huge volcanoes were located in one place, while on Earth these huge volcanoes are in different places, also the question arises how a relatively small star like Mars can melt so much rock that would allow such a huge amount of eruptions ? By the way, there is currently no research answer to this question and it needs to be researched to better understand the stars in our solar system.
