The "twinkling" effect is caused by the passage of light through the earth's atmosphere.
Explanation:
The light from cosmic bodies, reflected or original, does not "twinkle", but remains constant. It is the effect of the observed light passing through the atmosphere that creates a twinkling effect on the ground.
This is another reason that space-based telescopes like the Hubble and James Webb are so valuable for accurate observations of cosmic phenomena. There is no atmospheric interference in space to affect the light reception.
