Astronomers have discovered seven Earth-shaped planets in the solar system. These seven planets revolve around a star close to the solar system. Scientists believe that life may exist on these seven planets. On Wednesday (February 22), the journal Nature published the news of the discovery of seven planets.
According to data published in the journal Nature, NASA’s Spitzer Space Telescope and several ground-based review agencies have found the planets. These seven planets orbit a star 40 light years from Earth.
This discovery has been mentioned as rare in the history of astronomy. The reason is that planets are shaped similar to Earth and can have water. Due to the existence of water, the climate of the planets may be suitable for life.
According to the researchers, the surface of seven planets may have liquid water levels. However, three of the seven planets may be suitable for life or habitation.
The study was led by astronomer Michael Gillon of the University of Liege in Belgium. He said that these planets are very close to each other and very close to the stars, which reminds us of the moon around Jupiter.
Gillon added that the star is still very small and the seven coldest planets are temperate. Which means that there is liquid water on the surface of the house and there is probably life.
The cool little star has been named Trapist-1. According to astronomers, the three planets E, F, and G in the constellation Trapist-1 are habitable and may contain oceans. Habitat here refers to an area at the position of the planets orbiting a star that has the potential to contain liquid water on that planet or the planet’s surface.
Scientists say that the telescope can study the atmospheric conditions of these planets.
Bryce-Olivier Demori, a professor at the University of Bern in Switzerland, said that if any of these planets had molecules in the ozone layer, it would be possible to identify them with the James Webb space telescope. This means that there is life on that planet.
“It’s safe to say that we don’t know much,” said Amauri Trudeau, a co-investigator and astronomer at the University of Cambridge. A lot of being livable can change that. First of all, we must review. Source: BBC.
