Kepler telescope discovered five potentially habitable star systems
A group of scientists from the University of Illinois (USA), after analyzing data from the Kepler telescope, discovered five new systems with double stars. Each of them contains a planet capable of supporting life, according to Frontiers in Astronomy and Space Sciences.
Several years ago, scientists created a program to determine the habitable zone of binary stars. In the course of the latest scientific work, they tested it on systems where there is at least one giant planet. Indicators such as the mass of stars and their brightness were taken into account.
Recall that the habitable zone is a section of a star system where planets can store liquid water on the surface.
“If a planet gets too close to its stars, its oceans could boil away. If a planet is too far away or even thrown out of the system, the water on its surface will eventually freeze, as will the atmosphere itself, like the CO2 that forms the seasonal polar caps on Mars, ”explained astrophysicist Siegfried Eggle.
All systems were discovered by the Kepler mission: Kepler-16, Kepler-34, Kepler-35, Kepler-38, Kepler-64, Kepler-413, Kepler-453, Kepler-1647 and Kepler-1661.
Two of them, Kepler-16 and Kepler-1647, proved to be unfavorable for the development of life. They contained giant planets, which, according to scientists, made “the entire habitable zone dynamically unstable.”
But five systems (Kepler-34, Kepler-35, Kepler-38, Kepler-64 and Kepler-413) may indeed have habitable worlds, with Kepler-38 particularly promising. The scientists noted that when they are convinced of the stable orbit of the exoplanets, they will be able to determine how much radiation they receive from the two stars.
“By simulating the evolution of stars and planetary orbits, we can estimate the actual amount or radiation that the planet receives,” they noted.
Earlier it was reported that the Hubble telescope recorded the most expensive asteroid in the solar system. Its cost exceeds $ 10 quadrillion.
