New camera captures images at 100 billion frames per second

Slow-motion photography is cool and all, but now a team of scientists has decided to use high-speed photography to track light as it travels through space. In this GIF, you’re looking at a pulse of light hitting and bouncing off of a mirror. Really. The researchers, based in Washington University in St. Louis, have used a technique called Compressed Ultrafast Photography (CUP) to chase the light at 100 billion frames per second.
