Using observations made with the Gran Telescopio Canarias (GTC) a study led from the Instituto de Astrofísica de Canarias (IAC) and the Universidad Complutense de Madrid (UCM) has confirmed that the asteroid 2023 FW14, discovered last year, is accompanying the red planet in its journey around the Sun, ahead of Mars and in the same orbit. With this new member, the group of Trojans which accompany Mars has increased in number to 17. But it shows differences in its orbit and chemical composition which may indicate that it is a captured asteroid, of a primitive type. The results are published in

An international scientific team, including researchers from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), have discovered magnetic waves in sunspots with such a high energy flux that they could keep the Sun's atmosphere at millions of degrees. The finding adds a new missing piece to the puzzle of why the Sun's outer layers are hotter than its surface despite being further away from the source of heat. The results are published in the journal Nature Astronomy. The Sun is powered by nuclear fusion of hydrogen at the core, where the temperature reaches

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. The article “The increasing effects of light pollution on professional
