TUI-1452b is an ideal candidate for further observation with the James Webb Telescope and is one of the best models of ocean worlds known to date.
A team of researchers led by scientists from the University of Montreal in Canada managed to find a new planet from the Sun that resembles Earth, but it does not contain any land, but an entire water ocean, one. Big crashing waves.
TESS is an observatory designed to search for exoplanets 400 times wider than its predecessor, Kepler. It was launched in 2018, and in just two years, researchers managed to find more than 20 thousand planets outside the solar system.
According to the study, based on TESS data, a slight decrease in the brightness of the star, which is much smaller than the Sun, called “TOI-1452” (TOI-1452), occurs every 11 days. Researchers predict that the planet is larger than 70 percent of the Earth’s orbit.
To understand the concept, imagine you pass a small iron ball in front of a lighted lamp. As the ball passes between you and the lamp, the amount of light coming from it is reduced to your eyes. This is what happens when scientists do this. They point their telescope at a star for a long time, and they find how much the star’s brightness drops over a period of time and then rises again, which happens because a planet has passed in front of the star. iron ball
But TESS alone wasn’t enough to study the new planet’s mass and water content, so the researchers used data from a special camera installed at the Montreal Observatory and the University of Montreal in Canada, as well as the same university’s SPIRou spectrograph. The three of them created a close-up of the new planet.
The new planet, called “TOI-1452 b,” is located 100 light-years away from Earth, and researchers’ observations have shown it to be a “water world,” but further research has found it to be deeper. Than that..
The team’s research revealed that it is a rocky planet like Earth, located at an average distance from its star that would allow liquid water to exist on its surface, but water on Earth is only a tiny fraction of its mass, only about 0.05. %, in the case of “Tui-1452b”, the study shows that water can make up to 30% of its mass.
This has attracted the attention of scientists because this ratio is similar to that found in some of our solar system’s natural moons, such as Jupiter’s moons Ganymede and Callisto, and Saturn’s moons Titan and Enceladus.
Therefore, this research team suggests Press release An official announcement from the University of Montreal says TUI-1452b is an ideal candidate for further observation with the James Webb Space Telescope, one of the best models of the ocean world known to date.
