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

Tras cuatro años de actividades, el proyecto Interreg EELabs llega a su fin y, como broche final, la noche del 14 de diciembre, a partir de las 22:30 UT (hora local en Canarias), retransmitirá la lluvia de meteoros de las Gemínidas a través del canal sky-live.tv desde el Observatorio del Teide (Tenerife) y El Anillo (Extremadura). Las llamadas “estrellas fugaces” son en realidad pequeñas partículas de polvo de distintos tamaños (entre fracciones de milímetros hasta centímetros de diámetro) que van dejando los cometas -o asteroides- a lo largo de sus órbitas alrededor del Sol. La nube de

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 with
