"We were pleasantly shocked when the model clearly predicted a temperature inversion," team member and University of Hertfordshire scientist Ben Burningham said in the statement."But we also had to figure out where that extra upper atmosphere heat was coming from." and Judy Schmidt.), leading Faherty and the team to conclude this is what the JWST had detected around W1935. The big question is, what is driving the aurora at W1935? — the stream of charged particles from the sun — is the major driver of aurorae for Jupiter, Saturn and Earth. These charged strike the planets' magnetic fields and travel down field lines, interacting with particles in the atmosphere.
