According to a new study, it is in these systems that life can exist on some small rocky exoplanets, because they have all the necessary conditions for it.
Scientists from Florida State University, USA, conducted a new study in which they proved that life could exist on approximately 30% of the exoplanets in the Milky Way, writes Forbes.
“These planets all orbit red dwarf stars. These stars are smaller than our Sun, cooler, and emit less heat and light. However, they form more -about 75% of the 200 billion stars in the Milky Way. data from studies of the distant 150 exoplanets orbiting red dwarfs using archival data from the Kepler space telescope, which has stopped its work, but detected more than 2,600 planets,” the researchers said.
According to them, the zone suitable for life is the region of space around the star, where there are planets with a relatively comfortable temperature, that is, where the temperature is not too low and not too high.
“If there is a more moderate temperature on such a planet, it means that liquid water can remain on the surface of the planet. For the appearance of life on Earth, this most important environment is necessary, that is, on other planets, the water can be a source of life. At the same time, if an exoplanet is in a zone suitable for red dwarf life, but too close in its orbit to its star, then strong flares and a lot of heat can prevent of any life that has appeared on the planet. where there is only one planet. There are about 2/3 of such systems in our galaxy, but the remaining about 30% of the systems consist of two or more exoplanets , “experts added.
We will remind, earlier in the center of the Milky Way “foreign” stars were found.
