Whether there is life on Mars, scientists have given new evidence. There is still a long way to go

According to a recent article in the journal communication biology, strong evidence of life on Mars has been found.

The team has been working with NASA for a decade to explore the origins of life on Mars.

The team found a group of bacteria in ancient volcanic rocks that they believe have properties similar to those of Martian rocks. The researchers drilled 125 meters deep and collected rock samples from 13.5 million to 104 million years ago.

Led by Suzuki, an associate professor at the University of Tokyo, the team used a special epoxy resin to coat the rock to restore the original rock samples. As a result, they found a variety of microorganisms, and in the crevices of these volcanic rock samples were hidden colorful and dazzling creatures.

These bacteria accumulate in the orange tunnel, forming a green spherical light. Underwater erupting volcanoes produce lava at 1200 ℃, and the lava breaks down into rock after cooling.

The width of the fissure on the rock is about 1 mm, which has a history of millions of years. There are a lot of clay minerals in it. These minerals attract bacteria, and bacteria settle and breed in the fissure. They are the habitat of bacterial bacteria.

It’s as dense as the human gut, with about 10 billion bacterial cells per cubic centimeter.

What is the connection between these ancient rock samples found on earth and Mars?

The researchers of this project believe that the cracks filled with clay minerals found in deep-sea rocks are likely to be similar to the minerals that may exist on the surface of Martian rocks.

This hypothesis is based on the fact that deep sea, like Mars, has low temperature, medium salinity, iron rich environment and basalt, which may change the rules of the game of searching for life in space.

Of course, among the many hypotheses, we all simulate and judge from the perspective of the earth’s conventional environment and human beings.

We all know that the survival of all life on earth and water have an inseparable role. After research, scientists found that the earliest life on earth is likely to come from the ocean.

Now life on land has evolved from marine life. So basically, it can be said that life on the earth is inseparable from water, which is the source of life on the earth.

Will there be some extreme life without water and people just live in some extreme environment?

In the 1980s, scientists discovered volcanic bacteria that can survive above the boiling point of water. This discovery was very inconceivable at that time, because previous studies showed that DNA structure would be destroyed in the environment above 80 ℃. And these newly discovered bacteria can live well in the hot temperature, but when they are put into cold water, they will die unexpectedly.

In 1894, scientist Carlo emery discovered the most cold fearing creature on earth, the polar ice worm. Scientists believe that the rare cold hardiness of ice insects can prove that there may be cold hardiness organisms like ice insects on other planets. They walk freely in the ice, live actively in the polar low temperature, and turn into a mass of slime when they heat up a little.

So there may be life on every planet, but now our research is more about the planet environment suitable for human survival, and this goal still has a long way to go, but the recent research on Venus still leads us a little light on the way to find the next suitable planet.
