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 first satellite developed by the Instituto de Astrofísica de Canarias,, which was launched into space last December, has sent back its first images. The quality of the observations shows the perfect performance of its DRAGO-2 infrared camera. The pointing test of its laser optical communications module has also been successfully carried out, making it the first Spanish satellite to use this technology. Today, at a press conference, the first images obtained with the ALISIO-1 satellite (Advanced Land-Imaging Satellite for Infrared Observations), an Earth observation satellite whose

An international collaboration, with participation by the Instituto de Astrofísica de Canarias (IAC), has found a system of six exoplanets orbiting a central star with a precise rhythm.This phenomenon, known as orbital resonance, is common during the starting phase of planet formation, but it is exceptional to find a system with such a large set of planets which conserves this kind of gravitational synchronism. This finding shows that the system has not undergone major changes during its six billion year history, so that it gives an unusual view of the formation and evolution of planets. The
