The white halo you can see on the pics is called the Prandtl–Glauert singularity (sometimes referred to as a "vapor cone"). It is the point at which a sudden drop in air pressure occurs, and is generally accepted as the cause of the visible condensation cloud that often surrounds an aircraft traveling at transonic speeds.
Inside the post, you will see that kind of pictures. That’s quite impressive.
