The Instituto de Astrofísica de Canarias (IAC) has opened the application period for the XXXVI Canary Islands Winter School of Astrophysics , which will be held from 17 to 22 November 2025. This edition is carried out in the framework of the CELESTE (Centre for Optical and Space Technologies of the IAC) programme funded by the European Union and will focus on key optical technologies for astronomy, a field that is driving 21st century discoveries about the universe. Applications will be accepted until Friday, 13 June. The IAC’s Winter School is renowned for its educational approach and

The new infrared spectrograph NIRPS, built with the participation of the Instituto de Astrofísica de Canarias (IAC) and installed on the 3.6-metre telescope at ESO’s La Silla Observatory in Chile, has achieved its first scientific results, with four articles published today in the journal Astronomy & Astrophysics and one more accepted for publication. The data confirm its ability to detect Earth-like planets in the infrared for the first time with a precision better than one metre per second. One of the papers, led by IAC researcher Alejandro Suárez Mascareño, confirms the presence of a

At the present time ground-based observatories have a wide range of instruments which can study the solar surface in the visible and infrared ranges. But it is not possible to combine these observations with those in the near ultraviolet, which cover the wavelength range from 200 to 400 nanometres, nor to maintain them for long periods due to the turbulence in the Earth’s atmosphere. In this context, the Sunrise III mission, in which the Instituto de Astrofísica de Canarias (IAC) is collaborating, “ has become the first observatory to obtain spectropolarimetric data simultaneously in the
