Green halo is an area of the planets that can allow life to appear
According to the report posted on the San San Astronomy & Astrophysicsthe newly discovered earth is called HD 20794 D, with a weight of 6 times larger than the Earth and located in an area of ”living area”.
This is an area from the central star at the distance that can allow liquid water to appear on the planet surface, thereby facilitating life to proliferate.
However, HD 20794 D moves in an orbits, not a circle, which means the distance between the planet and the center of the center oscillates based on the location of the orbit. Therefore, up to this point, scientists have difficulty determining whether there is a planet on the planet.
The clue about the existence of HD 20794 D super earth started in 2022, when Dr. Michael Cretignier of Oxford University ‘(UK) discovered a signal while checking data stored by astronomical station. La Silla in Chile.
Based on this information, a team of international researchers involved. They analyze data collected from 2 decades of observation before confirming the existence of the planet.
“The excitement is the planet near Earth (20 light years) brings hope to future space missions in taking more detailed images of this super earth,” said Dr. Cronigner. .
The researchers call HD 20794 D as a priceless pilot research for projects searching for signs of life outside the solar system.
“With its location in the living area and near the Earth, the planet can play an important role in future missions to identify the atmospheric characteristics of the extraterrestrial planets to search for these. Biological signs show the potential for life, “according to the researcher.
