In short, the Webb data confirms the existence of a carbon dioxide (CO2) gas plume around 3I/ATLAS with significantly lower levels of water (H2O) and carbon monoxide (CO), as reported a few days earlier by the SPHEREx space observatory team (in a paper accessible here).
3I/ATLAS does not feature a cometary tail that extends beyond the width of its coma, as was already evident from the higher resolution image taken by the Hubble Space Telescope (reported here).
Infrared spectroscopy of 3I/ATLAS at a heliocentric distance of 3.32 Earth-Sun separations was taken with the NIRSpec instrument onboard the Webb telescope. The spectral images at wavelengths in the range of 0.6–5.3 micrometers reveal a prominent carbon dioxide (CO2) dominated coma, with enhanced outgassing in the direction of the Sun, as well as the presence of much less water vapor (H2O), carbon monoxide (CO), water ice and dust. The derived ratio of CO2 to H2O output by number of molecules is 8, among the highest ever observed. The data implies an intrinsically CO2-rich nucleus. The low abundance of H2O vapor is surprising at the object’s distance from the Sun.
