Researchers have discovered a “aqua planet” that is very similar to the post-apocalyptic action blockbuster Waterworld, which starred Kevin Costner and was released in 1995.
They assert that the planet, which is located one hundred light-years away, has a surface that is entirely covered in water, much like the moons of Jupiter and Saturn.
It is a little bit bigger and heavier than Earth, and it is located at a sufficient distance from its star for there to be life on it.
An exoplanet known as TOI-1452 b was found by a group of researchers from a variety of countries around the world. This planet orbits one of two very small stars that make up a binary star system in the Draco constellation.
Charles Cadieux, a doctoral student at the Université de Montréal and a member of the Institute for Research on Exoplanets, served as their leader throughout the study (iREx).
The TESS space telescope, which is operated by NASA and searches the entire sky for planetary systems that are similar to our own, was the instrument that led the researchers to the exoplanet they were looking for.
It was possible for scientists to deduce the existence of a planet that is approximately 70 percent larger than Earth based on the fact that a signal from TESS showed a tiny reduction in brightness every 11 days.
“I am extremely proud of this discovery since it indicates the high level of our researchers and instrumentation,” said one of the researchers. remarked René Doyon, Université de Montréal Professor and Director of iREx and of the Observatoire du Mont-Mégantic (OMM).
“We were able to find this one-of-a-kind exoplanet thanks to the OMM, a particular instrument designed in our labs called SPIRou, and an innovative analytical procedure devised by our study team,” said the researcher. “SPIRou was designed in our labs.”
TOI-1452 is one of two stars in a binary system that are almost the same size. This star, which serves as the home to an exoplanet, is significantly less massive than the sun.
The TESS telescope views the two stars as a single point of light because they orbit each other and are separated by such a small distance – 97 astronomical units, which is around two and a half times the distance between the sun and Pluto.
However, astronomers were able to determine through additional observations that TOI-1452 b does in fact orbit TOI-1452.
After that, they worked for more than 50 hours to come up with an estimate of the planet’s mass, which is thought to be nearly five times that of Earth.
The rocky composition of the extrasolar planet TOI-1452 b is most likely similar to that of our own planet, yet the TOI-1452 b’s size, mass, and density all point to a world that is quite distinct from our own.
The average amount of precipitation on Earth is rather low. Even though it is sometimes referred to as the Blue Planet because approximately 70 percent of its surface is covered by ocean, water actually only makes up a negligible fraction of the mass of the planet, which is less than 1 percent. Despite this fact, the planet is sometimes referred to as the Blue Planet.
In recent years, astronomers have been able to identify and determine the radius and mass of a significant number of exoplanets with sizes ranging from that of Earth to that of Neptune (about 3.8 times larger than Earth).
Some of these have a density that can only be explained if a significant portion of their mass is composed of elements that are less dense than those that make up the internal structure of the Earth such as water. This is the case with some of the items in this group.
The term “ocean planet” has been given to refer to these fictitious worlds.
Cadieux stated that TOI-1452 b is among the most promising prospects for an ocean planet that we have discovered to this point.
According to “Its Radius and Mass Suggest a Much Lower Density Than What One Would Expect for a Planet That Is Primarily Made Up of Metal and Rock, Like Earth,” “Its Density Is Much Lower Than What One Would Expect for a Planet That Is Prim
There is a possibility that water makes up as much as 30 percent of the mass of TOI-1452 b. This is a proportion that is comparable to that of certain natural satellites in our Solar System, such as Ganymede and Callisto, which are Jupiter’s moons, and Titan and Enceladus, which are Saturn’s moons.
It is hoped that NASA’s brand new $10 billion (£7.4 billion) James Webb Space Telescope, which started scientific investigations last month, will find TOI-1452 b to be a suitable candidate for additional observation using its capabilities.
