Here's what the sky would look like if humans could see gamma rays (video)

Still image from a NASA animation showing the sky lit up by gamma-ray flashes, which are represented by pink spots that shrink as the emission dims. The animation was created using a year of data from the Large Area Telescope (LAT) aboard NASA's Fermi Gamma-ray Space Telescope.

A new NASA animation shows what the sky over Earth would look like to humans if we had evolved to see high-energy gamma-ray light rather than just the visible light spectrum. 

The animation represents a cosmic firework display created as Earth's atmosphere is belted by gamma rays from astrophysical sources and powerful cosmic events.
