This is a human aircraft (rocket, spaceship, etc.). ).

To see this effect, the following conditions must be met:

1, within 3 hours after dark, or 3 hours before dawn (there is still sunshine in the sky, and the sun does not enter the horizon).

2, about 80~300 kilometers outside the atmosphere, that is, at the height of the "ionosphere", that is, the formation of the "Northern Lights".

The plane is moving forward, and there is air jet.

4. Professionally, it is called "plume" (not wake, because the wake will not be so big and change so fast), which is a combination of ionosphere, solar wind, magnetic field, high-speed jet and plasma.
