Another planet excluded as potentially habitable like the earth

A recent Trappist-1 D observation using the Nirspec (Near-Infrared Specrograph) spectrograph by James Webb has not revealed any trace of water. Furthermore, methane and carbon dioxide on the planet, which has dismissed it from the race to discover a planet similar to the earth. In addition, Trappist-1 D being a rocky planet. For example, the size of the earth, and also the third from its star, was an object of interest in the circle of astronomers.

Given the distance that separates it from its star. Therefore, scientists thought that it could contain liquid water, which gives them even more reasons to think that it could be able to house life. While in the temperate area of its star, it performs a complete revolution around it in just four earthly days.

If its proximity to its star gives it certain another planet excluded potentially habitable advantages capable of promoting life. it also presents its share of drawbacks. As a red dwarf star, Trappist -1 is known for its volatility – it frequently emits high -energy radiation. These eruptions can thin the atmosphere of a planet, or even make it disappear completely. If this is the case of Trappist-1 D, this gives a valid explanation to the results obtained by webb.

The main author of an article on the study. Caroline Piaulet-Ghorayeb, said that the absence of an atmosphere could explain the results obtained by webb. She also suggested two other situations: an atmosphere too fine to be detected. the presence of thick high altitude clouds that would obstruct.

After having dismissed Trappist-1 D, the researchers think that other Trappist-1 planets could still have an atmosphere.

Although we have not found a large. daring atmospheric signature on the planet D, it is still possible another planet excluded potentially habitable that the external planets keep a lot of water and other atmospheric components. – Piaulet-slaryb.
