This is what happens when an object reaches the speed of sound barrier.

I've never seen it that visibly. Must be the engine location or something. Usually it trails behind. https://www.youtube.com/watch?v=6B4IVcCuIZE

Usually it trails behind.

Not always.

Is it like a framerate thing the camera picks up? I've never visibly seen it happen that way in person. ie. it happens so fast I wouldn't see it?

And it’s just at the right angle to sun for it to get illuminated like that.

Or the photographer has a powerful flash.

https://en.wikipedia.org/wiki/Vapor_cone

Pressure differences at high speed through moist air causes vapor to condense.

Some effect of an air braking maneuver or something?

yeah its hitting the sound barrier, I think the color is is just off due to the quality of the picture. it's basically from pressure difference in the air and water vapor cant be held in those areas of the atmosphere. I Think its called a "vapor cone", and you can get multiple ones depending on the shape of the aircraft.

then the sonic boom is kinda about the air pressure equalling out and the water vapor goes back into the atmosphere... so when the plane actually passes you here the boom. something like that.

this probably explains it better

This appears to be some sort of gateway to another dimension or somewhere. Perhaps an attempt at a 'big bang'.
