NASA Photographed Shock Waves, and the Results Are Incredible

What does supersonic motion look like? Well, now you can see it for yourself in incredible images recently captured by NASA.

The photographs are from a recent test of advanced air-to-air photographic technology and show the first-ever images of the interaction of shock waves from two supersonic aircraft in flight.

These eye-popping aerial shots feature a surprisingly NASA take first air-to-air images of supersonic shockwaves flying near top speed above Edwards Air Force Base in California. Dan Banks, a senior research engineer at NASA, said in a press release that the images represent a level of detail “I don’t think anybody has ever seen before,” calling the new data “a very big step.”

“We never dreamt that it would be this clear, this beautiful,” physical scientist J.T. Heineck, based at NASA’s Ames Research Center in California, said of the photos in the NASA news release. “With this upgraded system, we have, by an order of magnitude, improved both the speed and quality of our imagery from previous research.”

Shock waves are created by rapid pressure changes that occur when an aircraft travels faster than the speed of sound. NASA has been developing a technique called Schlieren photography that relies on air-to-air interactions to capture the effects of supersonic flight. A special hydrogen alpha filter, and cameras using the sun as a background to visualize shock waves from supersonic aircraft, make the images possible.

In reality, it can be hard to wrap your head around the process. Whether we can fully grasp how NASA managed to use a hydrogen filter on a camera at 1,400 frames per second doesn’t take away from the sheer beauty of the images. This is one of those times where the intersection of science and art truly gives us something special.
