The night sky filmed at 250 million frames per second


The flickering noise (green and blue pixels) is created by stars, the moon and the scattered glow of cities in the atmosphere.

The intermittent spots and ellipses (yellow and red) crossing the camera originate from the light emitted by particles created by the collision of light and cosmic particles of very high energy with the atmosphere of the Earth.

This is the same principle as particle collisions in LHC at CERN. Except that here the particles are accelerated by very distant black holes and that we use the atmosphere of the Earth as a giant detector.
