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

ESA’s Euclid space mission reveals its first full-colour images of the cosmos. Never before has a telescope been able to create such razor-sharp astronomical images across such a large patch of the sky, and looking so far into the distant Universe. These images illustrate the telescope's potential to create the largest and most accurate 3D map of the Universe to date. The Instituto de Astrofísica de Canarias (IAC) has led one of the first five Euclid Early Release Objects (ERO) programmes. 95% of our cosmos appears to be made of these mysterious ‘dark’ entities But we don’t understand what
