A numerical experiment conducted by two researchers at the Instituto de Astrofísica de Canarias (IAC), Daniel Nöbrega Siverio and Fernando Moreno Insertis, has allowed them to show, for the first time, how one of the most widely distributed structures in the solar atmosphere, the coronal bright points, can form and acquire energy by the action of the solar granulation. When the Sun is observed from space detectors of X-rays or the extreme-ultraviolet, its atmosphere is found to be full of bright points, both during solar active epochs when a large number of sunspots is observed, and during

The traditional Open Day at the Roque de los Muchachos Observatory was held on Friday August 19th. After a gap during the past two years because of the COVID-19 pandemic, the Instituto de Astrofísica de Canarias (IAC) and the scientific institutions which participate in the observatory, together with the Town Council of Garafía and its area of Culture have renewed the celebration of this community event. The aims of this open day, for the benefit of the population of the municipality of Garafía, are to explain the scientific activity carried out at the telescopes, and also to encourage

Through collaboration between the Instituto de Astrofísica de Canarias (IAC) and the Sociedade Portuguesa para o Estudo das Aves (SPEA) within the framework of the projects Interreg EELabs and LIFE Natura@night, on the night of the 12t to 13th of August, the sky-live.tv channel will broadcast the maximum activity of the Perseid meteor shower from Madeira and from the Roque de los Muchachos Observatory (Garafía, La Palma). Some 10% of the continental surface of the Earth is affected by light pollution, but if we take into account the SkyGlow produced by the effect of artificial lighting on
