JWST detection of a carbon dioxide dominated gas coma surrounding interstellar object 3I/ATLAS
Descripción general
Resumen del artículo
Observations of interstellar object 3I/ATLAS using the James Webb Space Telescope reveal a coma rich in carbon dioxide, with a CO 2 /H 2 O ratio much higher than typical Solar System comets. This might indicate a different formation environment for 3I/ATLAS, potentially in a CO 2 -rich region of its parent protoplanetary disk or in a low metallicity environment.

Using the James Webb Space Telescope, astronomers found an interstellar comet with lots of carbon dioxide gas, more than expected compared to local comets. It suggests this interstellar comet may have formed differently than comets in our solar system.
