The Canary Islands Institute of Astrophysics (IAC) is organizing the XXXVI Canary Islands Winter School of Astrophysics , which will be held in San Cristóbal de La Laguna (Tenerife) from November 17 to 22, 2025. Under the title "Key Optical technologies for Astronomy", the school will focus on cutting-edge optical and algorithmic technologies that will define the future of Astrophysics. This edition, led by Professors Jeff Kuhn (University of Hawaii and IAC) and Rafael Rebolo (IAC), will involve approximately 35 advanced Master's students, doctoral candidates, and early-career postdoctoral

During October, the Adaptive Optics System team at the Gran Telescopio Canarias (GTCAO) of the Instituto de Astrofísica de Canarias (IAC), in collaboration with the technical team at the Gran Telescopio Canarias (GTC or Grantecan), successfully completed the integration of the GRANCAIN instrument into the world's largest optical-infrared telescope. The installation was carried out at the GTCAO outlet on the telescope's Nasmyth B platform, a key step in initiating performance testing of the new adaptive optics system. This is the first scientific instrument to operate using the GTC's adaptive

An international team of researchers led by the Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL), has unveiled a breakthrough explanation for the origin of tiny, jet-like plasma ejections in the solar atmosphere, known as “nanojets.” These elusive events which are recently discovered by the NASA’s solar telescopes are thought to play an important role in heating and sustaining the solar corona at temperatures above one million Kelvin. Why Study Nanojets? For decades, solar physicists have been puzzled by the so-called “coronal heating problem.” While the Sun
