“Another Earth” Is Covered With Oceans And Could Be Alive!

French scientists conducted new calculations about the size of Proxima b, a planet about our closest star that has become the most likely candidate for finding life in the universe.

Recently discovered planet Proxima b contained in orbit our closest star may be covered with oceans. But scientists are not sure whether their latest calculations about the size and characteristics of the planet, which is called ‘other countries’ good or bad news for those who hope that in a future to go there to live.

The scientists say that the presence of water could mean that the Proxima a rocky planet with oceans as the Earth, but also that it is a planet that is completely covered with ocean.

Proxima b is located at 7.5 million kilometers from its star, which is about a tenth of the distance of Mercury from the sun. However, this distance should not be an obstacle to retaining water on the surface. Proxima Centauri is smaller star than the Sun and about 1000 times weaker, and astrophysicists the French Institute CNRS say it is in orbit that allows it to retain water on the surface, which can ask a question about habitability of this planet.

Astrophysicists have calculated that the radius of the planet between 0.94 and 1.4 radius of the Earth, and with 1.3 Earth masses, scientists concluded that the planet probably has liquid water on the surface and that can have life forms.

But only when completely measured radius of the planet we will know what he looks like. Scientists have a theory for the maximum and minimum estimate. In one planet is extremely thick and water on the surface would probably took 0.05 percent of their weight. In the second scenario Proxima b is half the water world, and half rock or planet is covered with a layer of the ocean deep and 200 kilometers.

From CNRS’s say that in these extreme conditions planet could cover a thin layer of the atmosphere which would make Proxima b could be potentially habitable.

Proxima b Centauri is the closest star to us, only 4 light-years, but with the current drives is still quite elusive. But this year we have seen announcements of projects for the development of rapid tiny robotic spacecraft that could theoretically for our life could come to this planet.
