TRAPPIST-1e
Trappist-1, already known to scientists, may after all have an atmosphere similar to that of Earth-rich in nitrogen (and in the habitable part of the star).
The trappist-1e exoplanet (belonging to the well-known trappist-1 system, a small red dwarf star with at least seven planets) is found in your star’s habitable zone, where water remains liquid – And an analysis suggests that it may have an atmosphere rich in nitrogensimilar to that of the earth, advances a.
Matthew Genge, researcher at Imperial College London and author of this week The Astrophysical Journal Letters, explains that the search for exoplanets with atmospheres
“The true complexity is that one can be at the right distance of the sun, but, If you have the wrong atmosphere, it can be a scorching hell Like Venus or a cold Mars, ”says Genge.
So far, researchers have data from four observations made by JWST, but expect 15 more next year.
“Astronomers are observing so many different exoplanets and, sooner or later, we will find one with one nitrogen -rich atmosphere and oxygen. And probably the only way to get an oxygen -rich atmosphere is with plants, with photosynthesis, ”he adds.
“If trappist-1e is habitable, just imagine what may have happened on this planet over the past 7.6 billion years,” says the researcher. “The older the planet is, the more likely it is, I would say intelligence.”
Until 2060, he says, he expects to find exoplanets whose data is difficult to explain without the existence of life.
