Looking for a better residence for humanity

The discovery of a certain planet to conquer long ago is no longer the subject of fictional novels.

Hubble and Kepler's orbiting and modern telescopes have illuminated the universe in search of extrasolar planets that meet species requirements. What are those requirements, a member of the International Astronomical Council is Boris Morozov, Russian Institute of Science and Technology, responding to this issue.

People are trying to find extrasolar planets suitable for life. (Illustration).

Our celestial bodies belong to the star type G2V - ie the bright yellow dwarfs, the surface temperature of 5,000 to 6,000 degrees Kenvin. Scientists have long found about two dozen ' twin brothers ' with the Sun, about 50 light-years from Earth, allowing us to assume that such stars are quite common in the Galaxy.

But recently in Rio de Janeiro, the International Astronomical Council (IAU), a group of scientists from different countries raised the question - do humans need to find planets in systems? like the solar system? They argue that human life is closer to stars with more spectral K class.

These stars are numerous, have a lower temperature than the Solar system stars (3,000 to 5,000 degrees K) and visible light is orange.

The ' older ' class K star systems are much more abundant than the Solar system and are most likely suitable for human habitation, satisfying the range of conditions of a planet in which humans live.

The condition is that it must have the same density as the Earth, but the size needs to be at least twice as large to retain the atmosphere and to have a thicker layer of ozone to block the radiation.

Another idea is that the planet must have greater gravity than Earth, not only for humans to live on its surface, but also for the Earth's plants and to reduce the chances of birth. some special organic life.

However, the International Astronomical Council agreed to find an extrasolar planet as one of the most important tasks of modern science. Scientists must pay attention to all celestial bodies in the universe, possibly the cradle of organic life or convenient for human migration.

What is the opinion of Russian scientists about finding a new planet outside the solar system? This question has been answered by Deputy Doctor of Mathematics, Boris Morrozov, Institute of Astronomy, Russian Federation of Science and Technology:

" The search for planets beyond the limits of the Solar System has long separated into a special direction of Astronomy. People have seriously considered the possibility of migrating to a very distant planet. It is in the universe because the reality has proved that in a while, the Earth will no longer be suitable for human habitation.

What will the new house of humanity look like, different opinions. Our understanding of planets and stars is always supplemented by new data, so we don't exclude 100 years later we will find not orange dwarfs but White stars. giants or other celestial bodies, but now we have not figured out where the planet is with natural conditions.

About stars in K class, they are too cold for humans. If there is a suitable atmosphere for breathing, the temperature is still too low to stay.

The fact that we are currently in a state of embarrassment: has not released satellites that visit these distant planets outside the Solar System to observe carefully while human migration requirements have been set. Even when starting to conquer the universe, this process will take place very slowly because no strategy has been worked out.

The search for a new planet outside the solar system attracted not only the attention of narrow-minded scientists but also all social classes. It is the beginning phase that is very important to the future of all humanity . '
