This is the conclusion reached by scientists who have studied the activity of stars and the composition of the atmosphere of new worlds.
Researchers at Boston University conducted extensive research, during which it was found that about half of the potentially habitable planets outside the solar system may be uninhabitable.
Scientists came to this conclusion after a thorough spectral analysis of all discovered planets. According to scientists, radiation from nearby large stars can affect the atmosphere of exoplanets in the same way as super-strong solar activity. The atmosphere of some exoplanets could simply "evaporate" over millions of years of such an impact.
The scientists took the solar activity model as the basis for the mathematical model for calculating the effect of stellar radiation. After calculating the emission factors for solar energy, scientists noticed the similarity in the activity of other large stars.
The result of the work was the conclusion about a much stronger magnetic field of exoplanets. Scientists have come to the conclusion that in order to preserve their own atmosphere, potentially inhabited planets must have a strong magnetic field, tens of thousands of times higher than that of the Earth.
