Astronomers have discovered seven Earth-sized planets in the Solar System. These seven planets orbit a star near the solar system. Scientists believe that there may be life on these seven planets. On Wednesday (February 22), the journal Nature published the news of the discovery of seven planets.
The planets have been detected by NASA’s Spitzer Space Telescope and several land-based review agencies, according to data published in the journal Nature. These seven planets orbit a star 40 light years away from Earth.
This discovery has been described as rare in the history of astronomy. This is because planets are similar in size to Earth and may contain water. Due to the existence of water, planetary climates may be suitable for life.
According to the researchers, the surface of the seven planets may contain liquid water level. However, three of the seven planets may be suitable for life or habitation.
The study was led by astronomer Michael Gillen of the University of Lige 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 said the star is still very young and that the seven coldest planets are temperate. That is, there is liquid water on the surface of the house and maybe life exists.
The cool and small star has been named TRAPPIST-1. According to astronomers, the three planets E, F and G in the TRAPPIST-1 constellation are habitable and may contain oceans. Habitat here refers to the area in the case of planets orbiting a star that has the capacity to hold liquid water on the surface of that planet or planet.
Scientists say that the telescope can study the atmospheric conditions of these planets.
Professor Bryce-Olivier Demory from the University of Bern in Switzerland said that if the ozone layer of any of these planets contained molecules, it would be possible to identify them with the James Webb Space Telescope. This means that life exists on that planet.
“It’s safe to say that we don’t know much,” said co-researcher and astronomer Amaury Trudeau from the University of Cambridge. Being livable can change a lot. First and foremost we need to review. Source: BBC.
