Meet Janssen, A World 41 Light-Years Away That May Have An Atmosphere
==========
Scientists using the James Webb Space Telescope may have detected an atmosphere around an exoplanet called Janssen (also known as 55 Cancri e), which is 41 light-years away from Earth. Janssen is a rocky planet that is nearly twice the diameter of Earth and is classified as a 'super-Earth' or 'sub-Neptune.' Despite being a hot lava world with intense radiation, observations show that Janssen may sustain a gaseous atmosphere, possibly composed of carbon monoxide or carbon dioxide. The findings extend the scope of planets that may contain an atmosphere, but it is not expected to have signs of life. The discovery of Janssen's atmosphere could provide insights into the early Earth, Venus, and Mars. The study was conducted by scientists from NASA's Jet Propulsion Laboratory and the University of Bern.
