Scientists are in the midst of the TEXOPLANET TAPIST-1 E with NASA’s James Web telescope. The precise analysis of the results so far represents many possible scenarios of what the planet’s atmosphere and surface may be, as the scientific tasks in NASA laid the main basis for answering the question, “Are we alone in the universe?”
“We give us the infrared Webb tools more details than we can access them before, and the four initial notes that we were able to make from the planet E show us what we will have to work with when the rest of the information comes in the research team,” said Nestore Espinoza of the Institute of Telemore Teamor, a major investigator in the research team. two scientific papers In detail, the team’s initial results are published in the astronomical magazine messages.

Among the seven worlds of the Earth’s size around the Red Star Trapping-1, the planet E is of particular importance because it revolves around the star at a distance in which water on the surface is theoretically possible-not very hot, not very cold-but only if the planet has an atmosphere. This is where webb comes. The researchers were targeting the powerful Nirspec tool (close to infrared spectrum) in the system where the planet E was transferred, or passed in front of its star. The light of the stars that pass through the planet’s atmosphere will be absorbed, if there is one, is partially absorbed, and the corresponding decreases will be told in the optical spectrum that reaches the web of astronomers about the chemicals there. With every additional crossing, the contents of the atmosphere become more clear as more data is collected.
Although multiple capabilities remain open to the planet E because only four transient operations have been analyzed so far, researchers feel confident that the planet still has an atmosphere or an original. Trappist-1 is a very active star, with frequent flares, so it is not surprising to researchers that any hydrogen atmosphere that may have been stripped through stars. Although many planets, including Earth, build a secondary atmosphere heavier after losing their primary atmosphere. It is possible that the Planet E has never been able to do so and has no secondary atmosphere. However, the researchers say there is an equal opportunity to have an atmosphere, and the team has developed new approaches to work with Webb data to determine the potential Planet E atmosphere and surface environments.
The researchers say that the carbon dioxide is unlikely to dominate the atmosphere of Trapping-1 E, similar to the atmosphere of the thick flower atmosphere of Mars. However, researchers are also keen to note that there are no similarities directly to our solar system.
“Trapping-1 is a star completely different from our sun, and therefore the system of planets surrounding it is also completely different, and it challenges both our theoretical and theoretical assumptions,” said team member Nicole Lewis, an associate professor of astronomy at Cornell University.
If there is liquid water on Trappist-1 E, the researchers say it will be accompanied by the effect of the greenhouse, as it preserves different gases, especially carbon dioxide, on the atmosphere and warm planet.
Lewis said: “The effect of a little greenhouse has a long run,” and the measurements do not exclude sufficient carbon dioxide to keep some water on the surface. According to the team analysis, the water can take the shape of a global environment, or cover a smaller area of the planet where the star is in the permanent noon, surrounded by ice. This will be possible because due to the sizes of the TRAPPIST-1 planets and the orbits near their star, they are all closed, with a single side that always faces the star and one always always in the dark.

Espinoza and co -investigator Natalie Allen of Johns Hopkins University are currently leading a team that currently performs 15 additional notes for the Planet E, with an innovative development. Scientists make the timing of notes so that webb holds both planets B and E in the star currency directly after the other. After the previous web notes of the Planet B, the planet around which the closest to Trappist-1 is a bare rock without an atmosphere. This means that the signals that were discovered during the crossing of the Planet B can be attributed to the star only, and because the planet E wanders almost the same time, there will be a complexity less than the contrast of the star. Scientists are planning to compare data from both planets, and any indicators of chemicals that appear only in the Planet E Spectrum can be attributed to their atmosphere.
“We are still really in the early stages of learning any kind of amazing science that we can do with Webb. It is amazing to measure the details of the light of the stars around the planets with the size of the Earth 40 light years and we learn what it might be there, if life is possible there,“ Ana Glding, “Ana Glideen”, a researcher in Massachusetts in Massachusetts Technology in the field of space research, and from research Possible space of space. E. “We are in a new era of exploration, it is very exciting to be part of it,” she said.
The four transport operations of the TRAPPIST-1 E, which were analyzed in the new papers published today by the dreams of the Jwst Telescope Scientist team (deep survey of the atmosphere of the external planets using multilateral spectral analysis).
The James Web Telescope is the world’s leading space science observatory. Webb solves puzzles in our solar system, and looks beyond far from other stars, and investigating mysterious structures and the origins of our world and our place in them. WeBB is an international program led by NASA with its partners, the European Space Agency (European Space Agency) and CSA (Canadian Space Agency).
