Planets that are able to shelter earthlings

Scientists do not tire of continuing to search for planets on which life can exist. They can’t put up with the fact that earthly civilization is the only one in the entire Universe, and it has no brothers in mind. From the realization of this, it somehow becomes uncomfortable. Really, the mystery of the Universe will never be revealed: who are we, where, from, and what are we doing in the Universe – the only ones, without any good neighborliness?

Meanwhile, as shown by the results of many years of research by scientists, on some planets there may be conditions for living organisms. What reason do space scientists have to suppose? And what special exoplanets can indicate that they have life?

Mars

Mars, or the mysterious Red Planet, as it is also called, is especially attractive in this regard. And that's why. Firstly, it is in the solar system, which means it is the most reachable. It has already been visited by space rockets, which brought to Earth a lot of images from the surface of Mars.

In addition, there is an atmosphere on Mars that protects the surface of the planet from cosmic radiation. Theoretically, here you can even adapt the temperature indicators to vital. Perhaps there is even water on Mars, although the latter has not yet been exactly confirmed.

But there is a very serious problem: a very rarefied atmosphere and a low content of oxygen necessary for life. Therefore, even if someone dares to settle on Mars, living for him will not be easy: all the time he will have to be only in an airtight dome, or a spacesuit with an oxygen cylinder.

Planet Kepler-62 e

This planet is outside our solar system, so it will be difficult to get to it. Although it is assumed that there are conditions on this planet that are potentially favorable for the emergence of life. According to some assumptions, the entire surface of this planet is covered by a giant ocean. But these are just assumptions. You can’t even send a rocket to this planet, which is located at a distance of 1200 light years from us: it will not fly.

The planet Kepler-62 "e" is illuminated by the star Kepler-62 from the constellation Lyra. However, the light intensity here is much lower than the sun. The temperature on this planet is 17 degrees Celsius. This phenomenon, scientists called the "eternal spring."

Tau whale e

This planet is illuminated by the star of Tau Ceti, similar to our Sun.

The atmosphere here is very dense, so it does not transmit light well.

The average temperature on the planet is plus 70 degrees Celsius. Not comme il faut. The year on the Tau Ceti e lasts approximately 168 earth days. The planet itself is 4 times larger than Earth. It is unlikely that there can be anything living other than bacteria.

Zarmina (Gliese 581 g)

This is a completely new planet that scientists discovered relatively recently – in 2010. It is located in the constellation Libra, and the path to it from Earth will take 20 light years.

Based on the data that scientists obtained through research, theoretically there are, although difficult, living conditions for living creatures on Zarmin.

Scientists suggest that the planet has water, rocky land and atmosphere. Gliese 581 g is illuminated from its star only on one side. The temperature on the unlit part is on average -34 degrees Celsius, and on the opposite side it can reach +70. Hurricane winds, which arise due to temperature contrast and strong gravity, can interfere with the development of life on the planet.

Kepler-22 b

A heated debate among scientists regarding the viability caused the planet Kepler-22 b. Optimists emphasize the temperature balance: -10-11 degrees Celsius, which may be suitable for life.

Pessimists make a reference to the impressive dimensions of this planet: it is 35 times heavier than the Earth. Under such conditions, the surface of this space giant will consist entirely of water, over which a cloud of gases hangs. What kind of life can we talk about under such conditions when the only solid body on the planet is its core?
