A team of researchers from the University of Michigan has identified a temperate exoplanet, as a promising world of ice or water with super-Earth characteristics, LHS 1140 b.
This is the image they have published that is an illustration, it would be larger than the Earth, but the interesting thing is that it would have a lot of water, the findings have been led by the University of Montreal, although there was also an astronomer from the University of Michigan.
It is probably a mini Neptune, that is, a planet smaller than Neptune and larger than Earth, it would have a thick atmosphere rich in oxygen, it would be located 48 light years away, it would be within the habitable zone, although in the outermost zone, therefore So if it has as much water as it is suspected to have, because it is suspected to have a huge, global ocean of liquid water, much of that ocean would be frozen.
The data with which this study has been carried out has been thanks to the James Webb space telescope, data that was collected in 2023. But other data has also been added to have a more complete picture of this world thanks to the Spitzer, Hubble, and TESS with them have managed to solidify this result that has been published in a scientific journal.
It is estimated that between 10% and 20% of its mass may be composed of water, it is called LHS 110b and it is a candidate for an aquatic world, it would not be the first, remember that we are awaiting the results of another somewhat aquatic world. smaller than this and which is also in the habitable zone, which we know has water and that James Webb's analysis reveals that it has a type of gas that at least here on Earth is only a product of the action of life and specifically of those of life forms that inhabit the ocean.
These things do not go as fast as we would like, we have to analyze, we have to review the data, we have to make observations again to confirm what has been seen previously and compare all the data to be sure of the statement, but it would be a news, in the end it would not be 100% confirmation that we have found life, it would be necessary to get there, but we would be at 95%, because it would mean that we have found a planet in the habitable zone, a planet with water and a planet that It produces or has in its atmosphere a type of gas that is only produced by living beings, at least those we know here on Earth and also living beings that inhabit the Earth's oceans.
Furthermore, imagine that this aquatic world would not be like those of the Earth's oceans, the Earth's oceans have the maximum depth in the Mariana Trench, which is 11,000 odd meters.
but the normal average of an ocean would be 3000 - 4000 meters, which would be the ocean floor, but these oceans, these oceans of oceanic planets, we could easily be talking about tens of kilometers or perhaps hundreds of kilometers deep.
They have so much water that the bottoms of those oceans, the water can be under pressure conditions that are not normal here on earth and special conditions can occur, obviously for humans who like dry land, although we like to bathe in the sea. In summer it would be something quite uncomfortable and complex, but if they form, if life forms are created in those worlds, it would be paradise for them.
