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

The "Astronomy Education Adventure in the Canary Islands 2023" will take place in Tenerife from 17 to 21 July and will mainly focus on research on the Solar System and extrasolar planets, highlighting the work carried out at the IAC and the Observatories of the Canary Islands. The Instituto de Astrofísica de Canarias (IAC), together with other scientific and educational institutions, is organising the ninth edition of the "Astronomy Education Adventure in the Canary Islands" (AEACI). Under the title "Other Worlds", the latest discoveries and advances in research on extrasolar planets, the

The POLMAG research group of the Instituto de Astrofísica de Canarias (IAC) has released the public version of P-CORONA, a novel computer program for calculating the intensity and polarization of the light emitted by the million-degree plasma of the solar corona. This plasma diagnostic technique allows scientists to study the magnetic field of the solar corona by comparing their calculations with observations from the most advanced solar telescopes, such as DKIST and Aditya-L1. The solar corona is the outermost region of the solar atmosphere, where the explosive events that can seriously
