A new study has revealed that many planets may contain more water than previously thought, and this is the only thing that all life on Earth needs, making it habitable, as researchers from the University of Chicago studied a group of planets around a star M-dwarfthe most common form of stars found in the galaxy.
And according to the British newspaper “Daily Mail”, it turns out that the number of planets is much more than expected, consisting of half water and half rock, however, they say that the water is likely to be embedded in the rocks, rather than flowing as oceans or rivers. On the surface, as on the ground.
“It was a surprise to see evidence of so many watery worlds orbiting the most common type of star in the galaxy,” said Raphael Luc, the study’s first researcher.
While small planets are common around stars M-dwarfStudying them from Earth is a challenge because of the faint red light that their stars emit, and previous studies indicated that most of these planets are rocky or gaseous.
However, in a new study, researchers set out to understand whether this is really the case, or whether some planets are watery worlds.
The researchers used the Transiting Satellite to explore the exoplanets (he-goat) to study the radius and mass of 34 newly discovered planets around a dwarf M.
Their analysis revealed that the densities of a large proportion of the planets indicated that they were too light to be made of pure rock, and instead, it is likely that these planets were half rocky and half water.
While seeing a world completely covered in water might come to mind, the researchers suggest that’s likely not the case. Instead, the researchers suggest the water could be mixed with rocks, or in pockets below the surface.
