Scientists find micro-organism ecosystems three miles underground

Have you ever asked questions about the existence of another life under our earth? Or about extraterrestrial beings living thousands of years?

Scientists have discovered ecosystems of underground microorganisms twice as large as the world's oceans. The results of this report are presented at the American Geophysical Union Forum in Washington DC.

Citing The Guardian, Deep Carbon Observatory researchers say that the diversity of these underground species rivaled the ecosystems of the Amazon and the Galapagos Islands.

But unlike these places, the subterranean living environment is usually still pure because it has not been touched by human hands.

Although the conditions in "Deep life" are very hot, there is no light and nutrients are very small, but scientists estimate that the biosphere that lives in the subsoil has 15 billion tons of micro- organisms and 23 billion tons, hundreds of times the total weight of each human being. to be on the planet.

The world of the lower biosphere varies according to geology and geography. Their combined area is estimated at more than 2 billion cubic kilometers, but this can be further expanded in the future.

"It's like finding new reservoirs in life on Earth, we've found a new kind of life all the time, and it has turned out that life is such on Earth," said Karen Lloyd University of Tennessee in Knoxville. as reported by The Guardian.

The creatures were found in soil samples taken less than 3 miles from the surface and in samples from the mine. The results show that 70% of the Earth's bacteria and archaea are beneath the surface, including thorny Altiarchaeals living in sulfur springs and Geogemma barossii, unicellular organisms found in 121C hydrothermal vents on the seabed.

Research over 10 years has also revealed that an organism living 2.5 km below the surface has been living for millions of years and may not be dependent solely on solar energy.

"The strangest thing for me is that some organisms can exist for thousands of years." They are metabolically active with less energy than we thought to support life, "Lloyd said.

Colwell, a microbial ecologist at Oregon State University, made the same observation.

He explained that the life in the underground life was completely different. Some microorganisms have lived for thousands of years, moving almost only by tectonic plates, earthquakes or unstable volcanic eruptions.

"We are geared to a relatively fast process, namely the sun-based day cycle or the moon-based lunar cycle, but these organisms are part of a slow cycle that continues to live and move in the lapse of time. geological time, "said Colwell.

The scientists explain that their discovery was made possible by two technical advances, namely the ability of scientists to continue training to descend under the Earth's crust and the microscope technology that allows microbial life to an increasing level. advanced.

The study involved 1,200 scientists from 52 countries in various disciplines ranging from geology to microbiology to chemistry and physics.


Scientists do not reject the many mysteries to reveal. There are still many unknowns and scattered secrets that must be revealed below.

"There are lives everywhere and many surprising and unexpected organisms," said Mitch Sogin of Woods Hole's marine biology lab.
