The Director of the Starlight Foundation, and researcher at the Instituto de Astrofísica de Canarias Antonia M. Varela Pérez has contributed to a monographic edition of the prestigious journal Science dedicated to light pollution and its consequences. The starry sky has been a source of inspiration throughout human history. Astronomy has been a common element in all cultures and civilizations, and has been used to establish calendars, to navigate and discover new lands, and to drive many scientific and technical advances.

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. TheAdvertised on

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 OPAdvertised on
