60 billion planets can support life

In addition to some of the planets that support human life, there are still billions of other planets in the universe that can.

Research published last month in the astrophysical journal Letters Astrophysical Journal Letters said that according to new estimates by scientists, about 60 billion planets can support life in the Milky Way. All of these planets revolve around faint red dwarf stars.

Based on data collected from the Kepler spacecraft by the US Aeronautics Agency (NASA), scientists predict that no planet like Earth is in the life of red dwarfs. . But a group of experts recently reviewed and hypothesized, cloud cover could help shape the life of another planet.

Dorian Abbot, assistant professor in the field of geophysics at the University of Chicago, said the clouds caused warming and also cooled the earth. They reflect sunlight to cool and absorb infrared radiation, creating a greenhouse effect, causing global warming, but all of that is part of keeping the planet stable and sustaining life. .

The area of ​​life is defined as the area on the planet with the right temperature to keep water in liquid form on the surface. If a planet is too far away from the red dwarf, the water will freeze, but too close, the water will evaporate, because red dwarfs are dim stars, and have a lower temperature than the sun in the Solar System.

Researchers use 3D technology to simulate how air and moisture move on a tidal planet around a red dwarf star. The research team found that water on the surface will become clouds, cooling effect in the living area and maintaining water on the surface of those planets.

These findings provide scientists with a new way to identify the presence of liquid water on the surface of other planets with the James Webb space telescope, a new space telescope that will be launched. in 2018.
