An international team of scientists, with participation by researchers at the Instituto de Astrofísica de Canarias (IAC), has discovered a very large, but thin, stream of stars in the Coma cluster of galaxies. This is the largest stream of stars detected until now, and the first to be found in a cluster of galaxies. This finding, which is published in the journal Astronomy and Astrophysics, was made using observations taken with the William Herschel Telescope (WHT) at the Roque de los Muchachos Observatory (Garafía, La Palma, Canary Islands). The Coma Cluster is a large cluster of galaxiesAdvertised on

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 reachesAdvertised on

The first Canary Earth Observation Satellite, belonging to the Instituto de Astrofísica de Canarias (IAC), has successfully passed all the pre-launch technical tests, and is on the way to the United States for launch from California before the end of the year. ALISIO-1 ( Advanced Land-Imaging Satellite for Infrared Observations) is the first Canary satellite which will orbit the Earth, in the framework of the ALISIO space programme, led by the IAC and coordinated by the IACTEC-Space group. In 2018, the team gained its first success after the launch of an atmospheric sounding balloon withAdvertised on
