Aliens may have been on Mars 3.8 billion years ago

With so much effort, humankind finally proved that Mars used to have a dense atmosphere before.

Over time, the planet's magnetic field was too weak to protect the Red Planet from the Sun's destruction, causing the air to escape it.

Mars once had a dense atmosphere.

However, whether Mars was able to sustain life before was still suspected. The reason is because the planet is too far away from the Sun, so the surface temperature is not stable. According to images from Curiosity rover robots, the Martian surface was previously very cold, consisting of only sand and very barren.

But a recent study from the Georgia Institute of Technology (USA) and Seti (Search for Extraterrestrial Civilization) confirmed that below the planet's surface there was a thick layer of carbonates, indicating that The temperature on Mars was relatively warm and wet in the past, perfectly suited to nourish life.

According to Dr. Janice Bishop from Seti Institute: "The determination of ancient carbonate and clay beneath the surface of Mars shows that the climate on this planet was very different from today."

Mars is now proven to have liquid water flowing on it, but in the past it was a question of controversy, although many scientists have agreed with this.

And if water ever existed on the Red planet, scientists believe there will be a layer of carbonates and clay underneath - evidence that the place once had an environment perfectly suited to life.

Previously, these two things were found very little on the planet's surface. But so far, research has shown their evidence in Lucaya's tectonic plate, with a 3.8-billion-year-old carbonates and clay buried deep below 5 kilometers of lava.

Professor James Wray - research director - said their conclusion based on data from CRIMS Spectrophotometer (Compact Reconnaissance Imaging Spectrometer for Mars).

Research on the one hand adds evidence to show that life once formed on Mars, on the other hand, provides a potential area for research for future Red Planet exploration.
