LA PALMA, Spain, Sept. 2, 2026 - Very high-energy gamma rays are reaching Earth from a distant object called OP 313, and telescopes on the Canary Island of La Palma have caught them, according to a study published in the journal Astronomy & Astrophysics. Spain's research centre CIEMAT took part through the MAGIC Collaboration.^[1] The team analysed observations from the Large-Sized Telescope prototype, LST-1, and the MAGIC telescopes at the Roque de los Muchachos Observatory.^[2] LST-1 first picked up the emission from OP 313 in December 2023.^[3] Both instruments worked side by side at the observatory for the study.^[4] The detection came during LST-1's commissioning phase, the shakedown period before a telescope begins routine science. LST-1 is the prototype for the Large-Sized Telescopes planned for CTAO-North, the northern site of the Cherenkov Telescope Array Observatory.^[5] Space Nugget. Gamma rays this energetic never reach the ground. When one strikes the upper atmosphere, it sets off a cascade of particles that move faster than light travels through air. The cascade gives off a faint blue flash, called Cherenkov light, that lasts only a few billionths of a second. Cherenkov telescopes use large mirrors and very fast cameras to catch these flashes and trace them back to the patch of sky the gamma ray came from.
