"This image makes the invisible visible — the first American made civil supersonic jet breaking the sound barrier," Blake ...

For the first time, MIT scientists have successfully imaged how heat actually travels in a wave, known as a “second sound,” through this exotic fluid. Understanding this dynamic could help ...

We can't hear these sound waves, but when they reflect off different parts of the body, they create echoes that are picked up by the probe and turned into an image called an ultrasound scan.

NASA and Boom Supersonic have teamed to create a technique that visualizes the shock waves ... image makes the invisible visible — the first American-made civil supersonic jet breaking the sound ...
