The Cherenkov Telescope Array (CTA) is negotiating with the IAC to site more Cherenkov telescopes on La Palma. It’s not guarenteed that they’ll come here, but it’s highly likely. What is certain is that they’re going to build a prototype here.
So what’s a Cherenkov telescope? The oversimplification is that it’s a telescope to look at gamma rays instead of visible light. For more detail, see this article on the MAGIC Telescope, which is already on La Palma. The MAGIC consosts of two enormous telescopes, each with a segmented mirror 17 m in diameter. The new prototype will be 23 m in diameter, and the camera will be 3 m across.
