Astronomers have found that changeable stars, which become brighter and fade within just a few hours, distort information about the planets outside the solar system. The study is published in the journal Astrophysical Journal, writes Space.

Astronomers found that changeable stars can completely change the idea of \u200b\u200bthe planets that rotate around them. Scientists came to this conclusion after studying 20 planets outside the solar system using the Hubble space telescope.

The study showed that the vibrations of star light caused by hotter and colder areas on the surface of the stars distort data on the planets.

It turned out that the data on half of the studied planets were distorted by the variability of their native stars. If this factor is not taken into account, then you can receive incorrect data on the planets, including their size, temperature and composition of their atmospheres, astronomers say.

According to the authors of the study, the discovery was a great surprise for them, because they did not come to life that the star light could distort data so.

When the planets pass in front of their parent stars, there are failures in the star light, because it is blocked by a planet. These failures in the light of the star can be used to detect the planets themselves. And the period of time between the failures in star light can be used to determine the orbital period of the planets. Analysis of star light, which passes through the atmosphere of the planet, allows us to understand what it consists of.

According to scientists, if it is incorrectly interpreted by the data on stellar light, this may prevent the planet from detecting, and even if it is detected, it may prevent it from accurately determining its characteristics.

Astronomers say that some stars due to strong magnetic activity on the surface have darker and cold, as well as hotter and brighter areas.

Bright areas emit more light, that is, if the planet passes in front of the hottest part of the star, this can lead to the fact that astronomers will incorrectly determine the size of the planet. The fact is that it will block more star light. Also, astronomers may think that the planet has a higher temperature than it actually is, or that the planet has a denser atmosphere.

On the other hand, if the planet passes in front of the cold section of the star, then this may seem smaller and colder than it is actually.

As Focus already wrote, astronomers discovered the largest stream of black hole in the early Universe, which is twice as much as the Milky Way. Astronomers first discovered such a large -scale ejection of plasma from an ultra -massive black hole that existed when the universe was 1.2 billion years.

Focus also wrote that the European Space Agency will first send a unique landing apparatus to the moon, which will help in the development and study of the Earth's satellite.
