Une "planète infernale" dotée d'une atmosphère qui ne devrait pas exister a été découverte

Une planète "infernale", dont l'existence était jusque-là jugée impossible, a été découverte par l'observatoire spatial James Webb.

Het gaat om de vijfde planeet rond de zonachtige ster 55 Cancri. De naam van de ster ontleende men aan het sterrenbeeld Kreeft waar hij te vinden is. De exoplaneet heet 55 Cancri e en werd al in 2004 ontdekt en kreeg in 2004 de naam 'Janssen' naar Zacharias Janssen....

An article published in the journal "Nature" reports the results of a study of the exoplanet 55 Cancri e, formally called Janssen, which confirms the presence of an atmosphere that is considered secondary, which means that it derives from emissions coming from the planet itself. A team of researchers used observations conducted with the James Webb Space Telescope to detect traces of an atmosphere.

Webb detecteert secundaire atmosfeer op 55 Cancri e

Volgens nieuw onderzoek kan gas dat opborrelt uit een met lava bedekt oppervlak op de superaarde-exoplaneet 55 Cancri e een atmosfeer voeden die rijk is aan kooldioxide of koolmonoxide.

NASA’s Webb Hints at Possible Atmosphere Surrounding Rocky Exoplanet - NASA Science

While the planet is too hot to be habitable, detecting its atmosphere could provide insights into the early conditions of Earth, Venus, and Mars. Researchers using NASA’s James Webb Space Telescope may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date […]

Thick atmosphere detected around #planet that’s twice as big as Earth say #NASA's Jet Propulsion Laboratory
The so-called super Earth — known as #55CancriE — is among the few rocky planets outside our #solarsystem with a significant #atmosphere, wrapped a blanket of carbon dioxide and carbon monoxide. The boiling temperatures on this planet — which can reach as hot as 4,200 degrees Fahrenheit (2,300 degrees Celsius) – mean that it is unlikely to host life. https://abcnews.go.com/Technology/wireStory/scorching-rocky-planet-earths-size-thick-atmosphere-scientists-110026601

This diamond exoplanet lost its atmosphere — then it grew another

"We measured the thermal emissions from this rocky planet, and the measurement indicates that the planet has a substantial atmosphere. It is very exciting."
