NASA claims Proxima b Earth-like planet b does not support life

In a new NASA study, Proxima b Earth-like planets are unlikely to have life because its air-filled head is full of harmful radiation to organisms.

According to NASA, the atmosphere at Proxima b is constantly bombarded by harmful radiation, which leads to no life that can exist.

Proxima b is a planet that is about the same size as the Earth, and the planet with the closest distance to our solar system (about 4 light-years).

However, this distance is still too far for people today, so scientists decided to simulate the parameters we have about Proxima b on the computer to see if the planet supports the live or not.

A computer has calculated what happens to Earth if our planet orbits the same path as Proxima around its star mother, Proxima Centauri .

Proxima b is about the same size as the Earth.

NASA published its research in The Astrophysical Journal Letters, showing that our atmosphere will not exist if the Earth revolves around Proxima Centauri, a red dwarf star.

"We chose the only living planet that we know of as Earth on the site of Proxima b," said Katherine Garcia-Sage, a space scientist at NASA's Goddard Space Center in Greenbelt, Maryland. said.

In fact, although Proxima b is located in the habitat from its host, it does not mean that there will be life on this planet because life is made up of many other factors and must achieve all the essentials. Only then will there be hope to survive life on a planet.

Scientists calculate that at the location of Proxima b, the planet must receive hundreds of times more ultraviolet rays than the Earth is receiving. The amount of energy generated by these radiation rays removes molecules such as hydrogen, oxygen and nitrogen in the atmosphere of Proxima b, according to NASA.

Therefore, according to the new study, Proxima b lost the air in its atmosphere 10,000 times faster than Earth. This leads to the possibility of an atmosphere thick enough to support life on this planet.

"It will be interesting if an extraterrestrial planet retains its atmosphere, but Proxima's rate of loss of atmosphere is too high, so supporting the planet's life is impossible." , Jeremy Drake, an astronomer from the Harvard-Smithsonian Center for Astrophysics, co-authored the study.
