Scientists have captured the blast from a supernova 10,000 light-years away in a cosmic speed trap, clocking the shockwave from the dead star's explosive end at speeds of nearly 8 miles per second.
Also to know is, what is a shock wave and how is it produced?
This phenomenon is known as a shock wave. Shock waves are also produced if the aircraft moves faster than the speed of sound. If a moving source of sound moves faster than sound, the source will always be ahead of the waves that it produces.
What is a sonic shock wave?
A sonic boom is the sound associated with the shock waves created whenever an object traveling through the air travels faster than the speed of sound.
What is a normal shock?
"Normal shocks" are a fundamental type of shock wave. The waves, which are perpendicular to the flow, are called "normal" shocks. Normal shocks only happen when the flow is supersonic.
