These planets are older, warmer, wetter, and a little bigger than Earth, and some of them may be great places to look for extraterrestrial life. The study was led by Professor Dirk schurzer markucci of Washington State University, who made the latest discovery in collaboration with astronomers at the Max Planck Institute of the solar system and veranova University. < / P > < p > most of the extrasolar planets discovered so far by astronomers are not conducive to the survival of life, but there are also many planets in the habitable zone of stars, which may be suitable for the reproduction of life. Habitable zone means that the distance between a planet and a star is just right, so that its surface temperature is not hot or cold for life as we know it. It’s not only the habitability of these extraterrestrial planets that the team has the most potential to identify. < / P > < p > after analysis, the researchers have drawn the outline of a perfect “super livable planet”: the planet will orbit a K dwarf slightly colder than the sun (yellow dwarf), about 5-8 billion years old, 10% larger than the earth, with an average temperature 5 ℃ higher than the earth, oxygen content in the atmosphere between 25% – 30%, scattered land and abundant water, and plate tectonics or similar geological conditions In order to recover minerals and nutrients and create diverse habitats and landforms. In addition, the size of the planet’s satellite is 1% – 10% of its own, and it revolves around it at an appropriate distance. < / P > < p > based on this standard, they identified 24 celestial bodies, among which two exoplanets are Kepler 1126b and Kepler 69C, nine of them revolve around appropriate types of stars, 16 of them are of appropriate age, and five of them are of appropriate temperature. Only Koi 5715.01 meets all the above conditions, but its surface temperature depends on the intensity of greenhouse effect in its atmosphere. < / P > < p > the researchers said that since these 24 planets are all more than 100 light-years away from the earth, even with the most powerful telescope so far, some of them can not be studied now, but it is important to find out the reason why a planet becomes a “super livable planet”, because scientists are likely to find one of them within 100 light-years. If so, that planet should be the first choice for us to find out if there is any other life in the universe. < / P > < p > researchers believe that habitable planets can not be found only based on the habitable conditions of the earth. “We have to focus on finding the planets that are most promising for complex life, because there may be planets that are more suitable for life than Earth,” markucci said Skip to content
