The first Large-Sized Telescope (LST) prototype of the Cherenkov Telescope Array Observatory (CTAO), located at the Roque de los Muchachos Observatory (Garafía, La Palma), has made its first scientific discovery by detecting the source OP 313 above 100 gigaelectronvolts (GeV), a level of energy a billion times higher than the visible light that humans can perceive. It is the most distant quasar ever observed by gamma-ray instruments from the ground. On 15 December, the Large-Sized Telescope (LST) Collaboration announced through an Astronomer’s Telegram (ATel) the detection of the source OP

During commissioning the Canary satellite ALISIO-1 proves its efficiency by observing phenomena in over 100 regions of the world The first Canary satellite, led by the Instituto de Astrofísica de Canarias (IAC), ALISIO-1, (an acronym for Advanced Land-Imaging Satellite for Infrared Observations) was launched into space on December 1st 2023 from the Vandenberg Airforce Base in California, and in only a few months has completed the commissioning phase, the verification on orbit that all its systems are working correctly. In this phase of verification the DRAGO-2 camera has been calibrated, and

Researchers Julia de León and Javier Licandro of the Instituto de Astrofísica de Canarias (IAC) are participating in the Hera mission of the European Space Agency (ESA) , successfully launched from Cape Canaveral, Florida (USA) on 7th October at 14:52 UTC. This is the first European mission for planetary defence which together with NASA’s DART (Double Asteroid redirection Test) will study the effects of a technique for diverting asteroids called “ kinetic impactor”. The DART probe crashed into the smaller ( Dimorphos) of the two asteroids which form the binary system Didymos, on September
