2 billion years ago there were oceans on Mars! Scientists guessed like this

When it comes to the possibility of life outside the Earth, the biggest contender is the planet Mars. For years, scientists have been trying to find out whether there was ever life on Mars. Is there any such hope in the future? Many studies suggest this, but there is still a lot of research to be done. Now a study by the University of Paris has shown that there could have been liquid oceans on Mars 2 billion years ago. Scientists say that a liquid ocean may be possible if the temperature exceeds the freezing point, that is, 4.5 degrees Celsius. Such conditions on Mars were possible about 3 billion years ago from today.

However, a 2016 review said that the ancient climate of Mars was extremely cold due to low solar radiation and could not sustain an ocean. At the same time, another study from the year 2021 states that the planet has its own warming mechanism, which can allow lakes and rivers to flourish.

current study Researchers reconstructed the ancient climate of Mars using a three-dimensional model based on Earth’s climate model. Understanding this, scientists have come to the conclusion that two billion years ago there could have been oceans on Mars. Scientists have speculated the presence of an ocean in the northern hemisphere of Mars.

However some questions still remain. First, did life exist on this planet about 3 billion years ago? There is also a question that where did all the water go? One theory behind this is that due to the breakdown of water molecules into hydrogen and oxygen, it evaporated into space. One study says that the water of Mars is present in the form of ice under its surface.

Last year, the European Space Agency (ESA) said that a large amount of water has been found on Mars. It was told that water is hidden beneath the surface of the Valles Marineris Valley of Mars. The European Space Agency (ESA) and the ExoMars Trace Gas Orbiter (TGO) had discovered large amounts of water in this valley. However, this finding is still being investigated.

Many questions remain regarding the planet Mars. The scientists engaged in the search for life here have yet to prove a lot. Hopefully we will get some more interesting information in the coming time.
