NASA and Boom Supersonic captured a stunning photo of a shockwave emanating from the supersonic XB-1 aircraft as it flew in front of the sun.The photo required perfect timing and ideal conditions, and it was taken during a test flight.The image is a Schlieren photograph, revealing how light bends around air pressure differences during supersonic flight.The test flight data showed that the XB-1 aircraft made no audible sonic boom, which paves the way for faster coast-to-coast flights.
