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

International research led by the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) has found the first evidence of a massive galaxy with no dark matter. The result is a challenge to the current standard model of cosmology. The study is published in the specialized journal Astronomy and Astrophysics. A team of scientists, led by the researcher at the IAC and the University of La Laguna (ULL) Sebastién Comerón, has found that the galaxy NGC 1277 does not contain dark matter.This is the first time that a massive galaxy (it has a mass several times that of the

An international piece of research, led by the Instituto de Astrofísica de Canarias (IAC) has found clues to the nature of some of the brightest and hottest stars in our Universe, called blue supergiants. Although these stars are commonly observed, their origin has been an old puzzle that has been debated for several decades. By simulating novel stellar models and analysing a large data sample in the Large Magellanic Cloud, IAC researchers have found strong evidence that most blue supergiants may have formed from the merger of two stars bound in a binary system. The study is published in the
