Strange Green Glow From Interstellar Comet 3I/ATLAS Has Scientists Puzzled
Images of interstellar comet 3I/ATLAS snapped during the September 7 total lunar eclipse seem to suggest that latest visitor to our Solar System may be turning green.

That's not all that strange for a comet. Many Solar System comets give off a green glow when they heat up enough to emit vapor. However, for 3I/ATLAS, it might be quite strange:
observations of the comet's chemistry obtained to date show very few signs of the dicarbon (C2) molecules usually responsible for a comet's green glow. This could mean that the C2 is there, but yet to be detected. Or there could be another molecule responsible for making the comet appear green. Either way, the implication is that the chemistry of 3I/ATLAS still has some secrets it is yet to divulge.
