Astronomers have discovered a new exoplanet – meaning it lies outside the Solar System – that may be covered in water, which may be the first of its kind.

A team of astronomers from the University of Montreal has discovered an exoplanet orbiting TOI-1452, which is a star about 100 light-years from Earth.

Reporting their findings in the Astronomical Journal, the researchers say the exoplanet, known as TOI-1452 b, is slightly larger and massively larger than Earth.

Furthermore, its distance from its star means that its temperature could allow liquid to exist on its surface, as it would be neither too hot nor too cold.

Astronomers believe it could be an “ocean planet,” which means it could be completely covered in a thick layer of water, similar to some moons of Jupiter and Saturn.

Also like the moons of Jupiter and Saturn, water can make up up to 30% of the planet’s mass.

Although water covers about 70% of the earth’s surface, it makes up only 1% of the planet’s mass.

Charles Cadieux, a PhD student at the University of Montreal who led the team of researchers, told the Institute for Exoplanet Research: “TOI-1452 b is one of the best candidates for an ocean planet that we have found. until today.

“Its radius and mass suggest a much lower density than one would expect from a planet that is basically composed of metal and rock, like Earth.”

The bright star at the center of NGC 3132, while prominent when viewed by the James Webb Space Telescope (JWST) in near-infrared light, plays a supporting role in sculpting the surrounding nebula.  A second star, barely visible in the lower left along one of the diffraction peaks of bright stars, is the source of the nebula.  It has expelled at least eight layers of gas and dust over thousands of years (NASA)

The researchers hope to use NASA’s James Webb Space Telescope to further study the exoplanet.

Researcher René Doyon said: “Our observations with the Webb telescope will be essential to better understand TOI-1452 b. As soon as possible, we will book some time on the Webb to observe this strange and wonderful world. “
