New information shocked about 7 planets like Earth

Recently, scientists revealed the discovery that shocked the 7 planets like Earth.

Revealing about 7 Earth-like planets is receiving a lot of attention. Specifically, recently, scientists revealed more information about studies of seven new planets of the same size as the Earth, that they found the potential for life on the seven Trappist planets of the same size. with Earth.

In February 2017, researchers published information on 7 Earth-like planets orbiting the central star TRAPPIST-1 , a dwarf with a size of 1/10 of the Sun and a temperature of 1/4 . located 39 light years away from us. 6 of the 7 planets have a surface temperature ranging from 0-100 degrees C. 5 of the 7 planets have nearly the same width as Earth while the other 2 planets are slightly smaller.

Previously, astronauts had never discovered a star revolved around many Earth-like planets and had a relatively pleasant climate. Moreover, the Hubble Space Telescope and other observatories can detect chemical signals of any living creature on new planets.

Over a period of reconnaissance, the researchers found that in the viable region of the star TRAPPIST-1, the surrounding planets were not too hot, nor too cold. That is a favorable condition for the development of life.

The area of ​​the living area above this planet depends on the amount of hydrogen in the atmosphere. The volcanic eruption is the source of hydrogen gas for the atmosphere. Thanks to the interplay of gravity between planets, volcanic eruption is possible. Hydrogen from volcanoes will increase the area of ​​living areas on stars by 60%.

Two scientists Ramses Ramirez and Lisa Kaltenegger of Cornell University in New York State, USA, examined changes caused by volcanic activity on Earth-like planets. Accordingly, TRAPPIST-1h is the farthest planet among the planet TRAPPIST and outside the living area. But if volcanic eruption takes place, the planet will have water and life.
