The first observations of the W39b James W telescope for the atmosphere of an exoplanet by the spatial telescope James W, published Thursday, ont permis de constater the presence of autour CO2 of W-39b. Cette premierec composition chimique hors de notre Systeme solaire confirms that the telescope allows to understand the formation of Les Planetes les plus lointaines.
The humanitate is in vain, but it is still in the middle of our Solaire system. Du moins pas de manier certaine. The observations of the super-telescope spatial James W (JW) in Ont apporte, Thursday 25 a.m.û, la preuve definitive. For the premiere fois, du dioxyde de carbone to pu Ê, I repere in the atmosphere of an exoplanet (C'est-a-dire en dehors du systemme solaire).
On December 25, 2021, the œ reaches the Pleistocene of our galaxie pour chercher from CO2 traces. The autour de la Planeta W-39b which is found in" Seoul " 700 years-Lumiere De La Terre. I will compare, for example, the galaxie CEERS-93316 that the instrument James W a tenth weak aoû more than 13 milliards Annes-Lumiere De La Terre.

"On se doutait Qu'on finiait par trouver du CO2, mais c'est toujours bien d'avoir the confirmation that the JW nous allows effectivement of identifier cette important molecule in the atmosphere of an exoplanet", affirme Hannah wk, Astrophysicienne at the University of Bristol, member of the ecquipe de recherche internationale who holds the conclusions drawn from the observation of W-39b, seront published in the revue nature, le 29 aoû.
In 2008 ce qui resemblait a CO2 in the atmosphere of an exoplanet, mais "ce n'eteit que faisait penser a la presence du dioxyde de carbone", Note jer Leconte, astrophysicist at the University of Bordeaux qui ettait, lui aussi, member of the team ayant effectue the observations of W-39B. "The one, when on a VU Les relays transmis par JW, il n'y avait aucun doute possible", ajoute-t-il.
"Where N'avait jusqu'as a matter of simply passing the tools for detracter with certainty the presence of CO2," explains Hannah wk Agemaeford. The JW est, en effet, the first instrument of spatial observation in order to detect certain frequencies of waves in the infrared. Et c'est just within the cette zone that the dioxyde of carbone blocks the light. "Chaque molecule absorbed the light of different manner, when he confers a particular signature on the relevance of the telescope", Detaille Jorme Leconte.

This is the first time that CO2 is located in the atmosphere of an exoplanet. C'est is the first confirmation of the presentation of cette molecule in a plane of the type of W-39b, C'est-A-says a giant gazeuse similar to Jupiter, all confusing galaxies... and buy our Solaire system. The N'a, in effet, jamais pu Ê Qu'il and avait sur Jupiter OU Saturne.
Seen from Earth, this Discovery of carbon dioxide on W39B could easily give rise to ghosts of the presence of life. The CO2 emissions in the atmosphere generally come from living. They peuvent Ê productes the decline of the organic matter or well come from respiration animale.
But the hunters of extra-terrestrials go from their net to small green houses. ""The presence of CO2 in the atmosphere of a Planet is, in faith, a triplet indicating the presence of life," says Hannah wk. The atmosphere of Venus, for example, is saturated with carbon dioxide allors that are agitating in a plane that is particularly hostile to any form of life, if only caused by the high temperature on the surface (plus 400 °C).
W (AGEMASP)-39 B know (agemasp) as well as additional temperatures, avoiding 900 °C, in their atmosphere. Why then CO2? "This is the result of a chemical impression of carbon, hydrogen and helium - so many exogenous elements in the atmosphere of these exoplanets - with strong thunderstorms," emphasizes Jermy Leconte.

The detection of CO2 is no less essential for astrophysicists because "It is a good trip to understand the history of a Planet," notes Hannah wk. The presentation of this molecule provides, First of all, "a clear indication that the plane has an atmosphere", which is far from being the case for all the planets of the universe (in our own solar system, Mercury is not epochal).

Thus, the Data transmitted by JW in the atmosphere of W-39B-and note the concentration of CO2-allows a first observation: this Planet comes from elsewhere. Indeed, it actually finds itself very close to their star-as similar to our sun, the experts ask-and "the physically impossible that remains in this final place, it was able to accumulate so much CO2 and oxygen in its atmosphere", assures Hannah wkk. For her, he did not 1001 allows: W-39b to"group CO2 and oxygen atoms in their discharge from their training base to its current position". Now stick to where she came from.
THESE first observations by the JW of the atmosphere of an exoplanet on which you can confirm "that it is the possible reallocation of the EC gene of decade and to find molecules like CO2", enthuses Jermy Leconte.
