Astronomers have found a "double" of the Earth

6 июня 2020, 21:12
A planet has been discovered that resembles the Earth in size and distance to its parent star, which, in its' turn, is similar to the Sun.

Such a combination of similarities is incredibly rare, experts say, and therefore the found celestial body can become one of the best candidates for the role of an inhabited planet, reports Astronomy & Astrophysics.

In the case when the planet receives such an amount of heat from the star that water could exist on its surface (in the presence of a suitable atmosphere), then it is believed that the celestial body is in the habitable zone of its sun. Such a planet is most suitable for finding life on it.

Moreover, most of these planets, known to scientists, revolve around red dwarfs - small and relatively cold stars, the type of which include more than 70% of the luminaries of the Galaxy. On such stars, grandiose flashes often occur that can destroy both life and the atmosphere.

Stars of the solar type are calmer, but they are much less common. There are only a few percent in the galaxy.

In addition, to verify the existence of an exoplanet in such bodies, it is necessary to fix several of its revolutions around the star. For example, for aliens to detect the Earth, they will have to observe the Sun for several years.

Scientists emphasize that the worlds most promising in terms of habitability are perhaps the most elusive.

Recall that in September of this year, China plans to launch the world's largest radio telescope, which will specialize in the search for extraterrestrial civilizations.
