Cherenkov Telescope Array

The next-generation ground-based observatory for very-high-energy gamma rays, an array of imaging atmospheric Cherenkov telescopes being built across two sites — one in the northern hemisphere on La Palma and one in the southern hemisphere in Chile — to catch the faint blue flashes that gamma rays make in the atmosphere. The largest such observatory ever built.

Highlights

  • Two array sites, north and south, for all-sky gamma-ray coverage
