An international team of researchers from the University of Montreal and the Institute for Exoplanet Research announced the discovery of a planet called TOI-1452 b that is completely covered in waterlike the one shown in the 1995 film starring Kevin Cosner, called “Aquatic World”.

The new aquatic world was discovered in a binary system orbiting the star TOI-1452, located in the constellation of Draco, about 100 light years from Earth.

The research led by Charles Cadieux of the Université de Montréal, was published in The Astronomical Journalwhere he explains that the exoplanet, known as TOI-1452 b, is larger in size and mass than Earth; its star’s distance allows it to have a temperature that would be neither too hot nor too cold for liquid water to exist on its surface.

Astronomers think it could be an “ocean planet”that is, it would be completely covered by a thick layer of water, similar to some of the moons of Jupiter and Saturn.

TOI-1452 b is about 70% larger than Earth and five times as massive; its density could indicate that it has a very deep ocean. But more research will be needed.

It must be confirmed that it is an “aquatic world”

Oceanic planets were long imagined but they are hard to confirmand TOI-1452 b is no different, explains NASA.

The US space agency notes that if TOI-1452 b were to be shown to be a “water world”, your ocean could be quite deep. Although the surface of the Earth is 70% water, the terrestrial sea represents less than 1% of the Earth’s mass.

A simulation of TOI-1452 b, created by computer specialists from the team of scientists who made the discovery, showed that water could represent up to 30% of its mass.

TOI-1452 b makes a complete orbit of its star every 11 days, that would be the duration of a “year” on that planet. But because the red dwarf star it orbits is smaller and cooler than the Sun, liquid water could exist on the planet’s surface.

NASA assures that the planet TOI-1452 b must be investigated by the James Webb Space Telescope; because it is 100 light years away it is, in astronomical terms, quite close; the instrument should allow you to capture a spectrum of starlight to check if it’s an ocean planet.

Researchers from the discovery team say that will look to schedule a time at Webb to take a closer look.
