Jupiter is to blame for the absence of life on six planets

(ORDO NEWS) — Sun-like stars can have up to seven potentially habitable planets. The only condition is the absence of gas giants like Jupiter in such a system, said astrobiologist Stephen Kane of the University of California at Riverside.

For a long time, the specialist has been studying one of the closest star systems to Earth called Trappist-1, where there are three exoplanets in the habitable zone, according to the Astronomical Journal.

Kane noted that he was thinking about the number of potentially habitable planets in such systems. His team began to study, through mathematical modeling, how planets behave in various combinations. The algorithm also took into account the influence of gravitational forces to understand how the planets interact with each other over millions of years.

As a result, scientists found out that a number of stars can have up to seven potentially habitable planets on which water can exist. There could be six such planets in the solar system.

The reason that there is only one such planet in the solar system is Jupiter. The fact is that, ideally, the orbits of the planets should be round so that they do not intersect with each other, but Jupiter “violates” this principle by its gravity.

Earlier, astronomers were the first to trace the connection between magnetars and fast radio bursts.

Scanners from one of the observatories observed the SGR 1935 + 2154 magnetar and found that it emitted not only ordinary X-rays, but also radio waves. Thereafter, the Canadian radio telescope CHIME recorded a fast, high-power radio burst, with radio waves coming from SGR 1935 + 2154.
