Found life on Mars from microbial fossils

Researchers discovered fossils of microorganisms at Strelley in Western Australia, dating back 3.4 billion years before land and oxygen atmosphere on Earth, reinforcing the belief that life exists. on Mars.

Fossils were found in a stone in the form of quartz sand in Western Australia, by researchers at Oxford University and Western Australia, dating back 3.4 billion years ago, the oldest microorganisms. be found.

It proves that life has arisen when the land began to emerge from the oceans. At that time, volcanic eruptions created gases and lava. The moon was very close to Earth, creating large tides. Especially without oxygen to breathe.

Exaggerated images show spherical, oval, tubular fossils, like modern bacteria, and are about the same size from 0.01 mm and 0.02 mm. In addition, carbon and nitrogen substances were discovered in the cell walls, a sign of all living things today.

Some bacteria can eat pirite, a sulfur-rich iron compound, and produce sulphate as a waste. Others use sulphate and produce hydrogen sulfide, which smells like rotten eggs.

The discovery not only helps scientists discover the first life on earth but also supports the search for life elsewhere, like Mars, on ancient beaches and sandy beaches that have moved to rock.

Last year, Emmanuelle Javaux, a scientist at Liege University in Belgium, reported microbial fossils in sediments of 3.2 billion years old in South Africa.

With this finding, the fossil record of microorganisms was found to be more than 200 million years old, said researcher David Wacey at the University of Western Australia.

Currently the astronauts with the robots have gone to Mars to learn the Pilbara rock containing life. However, it has also undergone similar research to reinforce the belief that life has existed on this Earth's mysterious neighbor.
