Scientists: Living conditions in some planets will be better than Earth

Russia's APR Re reported a report on the discovery of planet-like planets orbiting the stars, making scientists and those interested in the field think we are not the only beings in this vast universe.


Living conditions on some of the planets discovered so far are not suitable for humans for several reasons, including the constant exposure of these planets to deadly radiation and ultraviolet radiation, and the level of explosions is much higher than the level of explosions on Earth, the site said.

The site confirmed that some scientists denied the possibility of life on some planets like the planet Proxima B, which is about 4.24 light years away from the Earth, because it is exposed to receiving X-rays about 250 times more than the ground. Proxima is constantly exposed to ultraviolet radiation at very high rates.

Until recently, scientists believed that no living organism could live in such conditions, but for some time, thanks to research by another team of astronomers at Cornell University, these findings were refuted.

According to American scientists, living organisms lived on Earth several centuries ago in extremely harsh conditions, including exposure to ultraviolet radiation and explosions. However, these organisms managed to survive.

Scientists have presented very persuasive arguments and explanations for the hypothesis of the possibility of life on other planets in the future.

In an article published by the Royal Astronomical Society, experts Lisa Catalinger and Jack O'Malley James of Cornell University suggested the possibility of extraterrestrial life even with high levels of radiation.

According to information provided by scientists, the ancestors of all living organisms on Earth today evolved during the ancient times due to exposure to ultraviolet radiation, several times the level of radiation on the planet Proxima B and other planets discovered.

Four billion years ago, the Earth was very hot and constantly exposed to ultraviolet radiation.

Despite those conditions that seemed unsuitable for the continuation of life on Earth, life received some kind of support and began to develop and thrive actively.

According to some scientists, some of the outer planets near the solar system can occur in the same process that the planet has seen for several million years.

The site pointed out that experts from Cornell University invented computer models of ultraviolet radiation environments of four planets outside the solar system closest to the ground, and assumed that live on its surface plants and organisms.

It is worth mentioning that the scientists chose Terabest-1, Planet Rus-128B, Proxima B, and El-Hash-S-1140.

The site said that these planets revolve around the red dwarfs, which unlike our sun often release large amounts of ultraviolet radiation in the surrounding area.

But scientists do not know exactly what climatic conditions exist on these planets, but they are sure that ultraviolet flashes sent by red dwarfs to these planets can destroy the biosphere and erode the atmosphere.

The high level of radiation can cause different types of mutations in living organisms and even destroy their DNA.

The site said that in order to obtain evidence of the evolution of life on the outer planets, the scientists devised several models of the processes that occur on the surface.

Scientists have been able to obtain virtual data about what could happen on the surface of these planets. In the next phase, scientists compared the results they obtained with the climate conditions that existed on the Earth's surface 3.9 billion years ago, in the era of the emergence of the first living organisms on the planet.

According to scientists at Cornell University, it is assumed that a large number of extraneous planets detected receive ultraviolet radiation much stronger than the radiation currently being exposed to the Earth.

But Terabest-1, Planet Ross 128B, Proxima B and L-HASH-1140 are much lower than the Earth's radiation of 3.9 billion years ago, which means that the climatic conditions of these planets are more likely to live than the Earth before 3.9 billion years.

In conclusion, the site noted that given the existence of life on Earth's surface 3.9 billion years ago, it can not be said that ultraviolet radiation and radiation may reduce the processes of life on other planets.
