Many scientists believe that Proxima b hardly has suitable conditions for developmental life.
In August 2016, ESO (European Aeronautics Agency) confirmed the existence of a Proxima b planet named "2nd Earth" in the extreme near us - only 4, 5 light years.
Proxima b revolves around its star in a period of 11 days, and with a "standard" distance to have a very balanced temperature, enough to maintain liquid water on the surface. This is said to be a sign of life on "2nd Earth".
Proxima b revolves around its star in an 11-day cycle.
However, scientists at Villanova University have recently suggested that Proxima is more likely than Tatooine - a rocky planet orbiting a binary star system, just like in a science fiction movie Star Wars (Star Wars).
Edward Guinan - Villanova University professor of astronomy, said the possibility is high that Proxima b has experienced "a hell" about 300-400 million years.
This is because Proxima b revolves around its star at close distance, equal to 1/20 of the distance between the Sun and Mercury. When Proxima was first discovered, this distance was considered to have potential for life.
The high possibility that Proxima b has experienced "a hell" is about 300-400 million years.
But now, researchers say, the two stars of Proxima b are called dwarfs . When young, they will fire X-rays and ultraviolet radiation - which can cause the planet to explode or vaporize any liquid on the planet.
Young stars also emit dangerous solar sparks and if there is a world turning around them - they can rip the atmosphere out of the planet.
Professor Edward Guinan said: "It is really difficult to survive on Proxima b". However, we still have hope to find aliens on it. "
Proxima b can still live if it has a strong magnetic field.
Victoria Meadows of the University of Washington: "Proxima b is still able to survive if it has a strong magnetic field, or has an abundance of hydrogen to protect. Otherwise, Proxima b must be farther away than its star. more now ".
The conclusion was announced at the American Astronomical Society meeting in Texas.
