"Hydrogen Sea" exoplanet or "cradle" of extraterrestrial life
Science and Technology Daily, Beijing, August 29 (Reporter Liu Xia) According to a recent report by the US Space Network, British scientists said that scientists looking for extraterrestrial life should expand their thinking! The "Hydrogen Sea" is an exoplanet or the "cradle" that breeds extraterrestrial life
.
This exoplanet is 2.
So far, the probes responsible for searching for extrasolar life have mainly focused on terrestrial planets, because the Earth is the only planet we know of that has life
.
But the universe is full of various planets.
In this new study, the researchers discovered a class of exoplanets-"Hydrogen Sea" planets
.
The members of the research team said that "Hydrogen Sea" planets seem to be extremely common throughout the Milky Way galaxy.
New research points out that the size of the "Hydrogen Sea" planet is similar to that of the "Super Earth" and the gas-like "Mini Neptune", but the density is somewhere in between
.
In addition, there are many types of "Hydrogen Sea" planets.
In addition, the "Hydrogen Sea" planet seems to be a good place to look for potential biosignal gases such as oxygen and methane
.
The researchers wrote in the paper: "We found that compared with rocky exoplanets, the'hydrogen sea' planet has a larger radius and higher temperature, making these biomarkers easier to detect
With the aid of the James Webb Space Telescope launched by NASA later this year, scientists may soon begin searching for life on the "Hydrogen Sea" planet
