According tomedia reports, the latest research by scientists shows that there are many “seaworlds” in the Milky Way. “Ocean World” refers to Earth-like planets with large amounts of water on the surface or underground, and in the solar system, some of the moons of Saturn and Jupiter belong to the Ocean World, for example, the existence of a large, liquid saltwater ocean beneath the surface of Titan. But how common are these seaworlds in the universe?

The scientists decided to analyze how many planets in the Milky Way fall into the “ocean world” category, and they plan to explore how many of these planets are like Titan, which sprays water ice plumes from the ocean. More than a quarter of the 53 exoplanets studied may be oceanic planets.
Lynnae Quick, a planetary scientist at NASA’s Goddard Space Flight Center, said: “The Ganymede and Titan spewed plumes, which come from the ocean beneath the ice crust, where the ocean’s huge energy-driven plume is a necessary condition for the survival of two known lifes. Therefore, if we think that these planets may be habitable, then there will be larger ocean icies in other planetary systems, suitable for life. “
To find out how many oceanic worlds the Milky Way has potentially had, scientists have observed 53 exoplanets similar in size to Earth, including seven in the nearby TrappisT-1 system. They also analyzed variable data such as the volume, density, orbit, surface temperature, mass, and distance from the star.
More than a quarter of the 53 exoplanets are likely to be oceanic worlds, most of which are under ice, and these ocean icies may release more energy than Titan and Ganymede. The assumptions into these mathematical models are well-founded guesses that could help researchers better select exoplanets to study or provide important clues about the future direction of the probe’s launch.
At the same time, future scientists could test new findings by measuring the energy released by these planets, or by identifying the eruptions of any volcano (the cryogenic volcano that sprays liquid, steam, rather than lava), which can be identified by filtering the planet’s atmospheric light (or wavelength of light).
These exoplanets are far away from Earth and are still unable to observe the details, especially since these planetary details are often obscured by stellar light. However, with the upgrading of space science and technology, the launch of the James Webb Space Telescope in 2021 will give researchers a deeper look at the mysterious planets.
Future missions to search for signs of life outside the solar system will focus on SeaWorld, which has a rich atmosphere and the conditions necessary for life in the solar system’s icy ocean moons, far from the sun’s heat.
