Would the northern lights still be able to be seen if the earth didn't have an atmosphere?
What about stellar scintillation; would that still occur without an atmosphere? Would parallax still work without an atmosphere?

Scientists have solved the mystery of the aroras. Our magnetosphere consists of flux, distorted by solar wiñd. When these lines of flux are broken, they produce an electric charge. Gasses in the stratospher react to this chàrge, like neon emits light when subject to charge.
No atmosphere, no aurora.
Likewise, nothing to cause light distortion, so n9 scintillation.
Parallax is a function of a triangle, so always exists.

No. The Northern Lights are the result of ionized particles impacting the atoms of our atmosphere; remove the atmosphere, and there's no impacts - and no northern lights.

The northern lights are the result of the ionized solar wind interacting with the nitrogen and oxygen molecules in the atmosphere.
If there was no atmosphere, there would be nothing for the incoming radiation to react with.
Parallax has nothing to do with an atmosphere, its the apparent change in location of a distant object with respect to a nearer object.

Nope. If Earth didn't have an atmosphere, it likely also would not have a magnetic field or radiation belts, either.

No. No, stars would not scintillate, twinkle. Yes, parallax would still work. Parallax works better without an atmosphere. That was the mission of the Hipparchos satellite.

parallax would be easier to measure without an atmosphere.
Scintillation is caused by atmosphere, so no air, no twinkle
Aurorae are a glow of atmospheric particles struck by electrons, protons, neutrons etc, so no air, no aurorae

no, northern lights are ionized atmosphere
stellar scintillation? twinkling stars? that is due to the atmosphere
parallax has nothing to do with atmosphere.
Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.
