A study conducted with the new WEAVE , installed on the Telescopio William Herschel (WHT) at the Observatorio del Roque de los Muchachos (La Palma), and in whose construction the Instituto de Astrofísica de Canarias (IAC) participated, has revealed clear signs of shock interaction in the Type II supernova SN 2023ixf. Almost a year after the explosion, the data obtained with WEAVE reveal complex emission features that provide new clues about the processes shaping the final stages of massive star evolution. SN 2023ixf, located in the nearby galaxy M101, is the closest Type II supernovaAdvertised on

The IACTEC headquarters has recently hosted the meeting between the engineering team behind the future European Solar Telescope and an international panel composed of some of the world's leading experts in the development of large telescopes and solar observation instrumentation. It is common for major scientific projects to undergo this type of scrutiny during their development as a way to independently verify their quality and viability. The evaluation process began over a month ago with the submission of all the design documentation to the reviewers. In this case, the evaluation focusedAdvertised on

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 theAdvertised on
