Can someone better explain the first picture on there? It has something to do with reaching the speed of sound but I am still unsure.

"The clouds appear for the same reason that clouds always form, namely, that the air has cooled to the point that the ambient water vapor condenses. Flows around bodies and wings always change the temperature and pressure of the fluid." for details see

Think of it this way:
You dive into a pool. The sudden impact of your body on the water creates a crashing sound, followed by waves spreading outward from the point where you hit the water. A plane punching through the air has a similar effect.
EDIT!!!!
OK, let me rephrase this a bit. If you dive in, and you do it just right, there is very little water being displaced, and little noise is created. Now do a cannonball. Your body glides less smoothly across the air/water boundary and you create this massive ripple.
Better?

The sonic boom (wherein sound waves overlap eachother) causes the moisture in the air to condense, and become visible.

thats a soni boom basically sayin that it makes a big blast of sound and if sound is that strong it becomes visible especciall if its at such a high pressured place
