You can clearly see the shockwaves.
The image above is fantastic.
It depicts a U.S. Air Force Test Pilot School T-38C passing in front of the sun at supersonic speed, generating shockwaves.
The photograph was taken by NASA for research purposes using a modern version of schlieren imagery, a 150-year-old German photography technique, used to visualize supersonic flow phenomena with full-scale aircraft in flight.
According to NASA, the results of the research will help engineers to design a quiet supersonic transport aircraft.
