Ok .. so here's the released
spectrograph results (albeit a bit crude . and dumbed down ..)
but even if your plasma was in dark mode, there'd have to be be some kind of reasonably large spectral signature in the 2 to 5 micron region to account for the jet activity. Plasma isn't invisible across the bands these guys were looking over. If it was close to flipping into the glow mode then it would be emblazened across the whole thing (same for arc mode). It would have to be in the dark mode and there'd still be some kind of signature …?
They say there's organics: methanol, etc. but nothing else.
Cheers
PS: I haven't had a chance to look over the footage again about the line of jets .. standby. Cheers
