Scientists want you to find cosmic rays using your phone's camera
Cosmic ray particles hit Earth's atmosphere all the time, but finding them is tough; even the most sophisticated detectors can only cover so much ground. Scientists at University of California might just have discovered an easy way to pinpoint these exotic elements, however: the camera on your smartphone. The team's upcoming CRAYFIS (Cosmic Rays Found in Smartphones) app looks for high energy particles hitting the camera sensor on your device as soon it's both asleep and charging. While one phone wouldn't collect much data by itself, a gaggle of them would be extremely powerful; 1,000 phones in a square kilometer (0.4 square miles) would capture virtually every particle zooming overhead. They could actually be more effective than existing detection arrays, which tend to oversaturate quickly.
