00:00Scientists just finished building a massive telescope array in La Palma.
00:04These advanced mirrors will capture high-energy gamma rays from deep space.
00:09Gamma rays come from exploding stars and massive, supermassive black holes.
00:14Special detectors track faint light flashes when radiation hits our atmosphere.
00:19Researchers hope this project unlocks hidden secrets about mysterious dark matter.
00:23Do you think ground telescopes are better than space observatories?
