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.
@Lazarou I wouldn't put any credit in that press release that clearly hasn't been fact-checked—no planet orbiting within one point blah "miles" of its primary has an orbital period of 17 hours! I mean, this is pablum aimed at the scientifically illiterate. Who do they take their readers for?
