An exoplanet with a deep ocean was discovered in the constellation Dragon, about 100 light-years away from Earth, through data from NASA’s planetary exploration telescope TESS, CNET and other foreign media reported on the 25th (local time). .
A research team led by Professor René Doyon of the University of Montreal, Canada, has discovered the binary exoplanet ‘TOI-1452 b’, which is located in the constellation of Dragon about 100 light-years from Earth through data from the Tess telescope.
About 70% larger than Earth and five times more massive, the exoplanet has water on its surface, and the temperature of the water is neither too hot nor too cold.
Also, an important point is that the density of water was observed, and this planet is a ‘sea planet’ with many parts covered by the deep sea.
“TOI-1452 b is one of the most suitable candidates for a sea planet among planets discovered so far,” said Dr. Charles Cadieux of the University of Montreal, one of the lead authors of the paper. It presents a much lower density than would be expected from the
The results of the study were recently published in The Astronomical Journal.
The researchers observed that up to 30% of TOI-1452 b’s total mass would consist of water. If this is true, it is thought to have the same proportions of water as Saturn’s bright and cold moon Enceladus or Jupiter’s largest moon Ganymede in the solar system.

Researchers predict that James Webb (JWST), who recently started scientific observations of the exoplanet, could unravel more of the planet’s secrets. “Fortunately, this planet is located in the year-round observable area of the JWST,” the researchers said in a press release.
Professor René Doyon, who also developed one of JWST’s major instruments, said, “Observation using JWST is essential to broadening our understanding of TOI-1452 b.
