About

The Cherenkov Telescope Array Observatory (CTAO) is the next generation ground-based instrument for gamma-ray astronomy at very-high energies. With 64 telescopes located in the northern and southern hemispheres, the CTAO will be the first open ground-based gamma-ray observatory and the world’s largest and most sensitive instrument to study high-energy phenomena in the Universe.
