On the planets TRAPPIST-1 found oceans with liquid water

The Hubble telescope provided the first hints on the possible water content in the planets of the TRAPPIST-1 system. An international group of scientists believes that liquid water is present in seven exoplanets of terrestrial type TRAPPIST-1. They are located 40 light years from Earth.

With the help of the telescope, traces of a hydrogen-saturated exosphere-the outer layer of the atmosphere-were found. Astronomers also were able to calculate the total amount of lost water on these planets.

According to Gazety.ru, American scientists believe that almost all the planets in the TRAPPIST-1 system are very similar to the Earth in terms of structure of the interior and atmosphere. It is alleged that three planets of seven are located within the so-called “zone of life”, where water can exist in liquid form. Scientists have hypothesized that the mass of planets is comparable to the mass of the Earth.
