Potential life support found on a foreign planet near Earth?


NASA recently revealed that Earth's closest exoplanets, Proxima Centauri b (Proxima b), are inhabited by humans.

In the official statement as quoted Phys, Tuesday, September 18, 2018, Proxima Centauri b ends up having the life of an organism through the source of water in it.

The results of this study, published in a scientific journal entitled Habitable Climate Scenarios for Proxima Centauri b with Dynamic Ocean. The research was led by Anthony Del Genio, a scientist at NASA's Goddard Institute for Space Studies.

Del Genio acknowledged that the presence of water on the surface of the planet has made the planet's ecosystem capable of surviving in various conditions.

Therefore, it can be said that the ecosystem is suitable to be a place to live of living organisms.

Not only is there evidence of water content, as Proxima Centauri b is also in a habitable zone from the position of the planet's orbit.

The planet orbits a star called Proxima Centauri, about 4.2 light-years from Earth, equivalent to 40 trillion kilometers.

Even so, astronomers need more time to study the planet's characteristics. Because, said Del Genio, the water content and habitable zone is not a guarantee that Proxima Centauri b can be inhabited by humans.

"We do not know that Proxima b has an atmosphere or not, without it, how humans can live," he said.

In addition, the characteristics of the star Proxima Centauri are also classified as red & dwarf category & # 39 ;.

According to Del Genio, this star is not as hot as the Sun, so the planets must be very close to getting light for the climate that supports life in it.

Although the planet is only about 4.2 light-years away, researchers say the possibility of visiting it is still far away. Especially with the launch of the space shuttle, especially with the existing technology.

Another problem that has not been solved is the exact location. The researchers said it was impossible for Proxima b to be formed at its current location.

According to an Anglada-Escude researcher, it is likely that the planet formed somewhere else and got there because of the migration.
