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 supernova

The four large sized telescopes of the CTAO on La Palma reach a key milestone in their construction The LST-2 telescope has successfully completed the installation of its camera support structure (CSS), making it the last of the four Large Sized Telescopes ( LST ) to reach this important milestone in its construction at the Roque de los Muchachos Observatory of the Instituto de Astrofísica de Canarias (IAC) on La Palma. This telescope is part of the ambitious CTAO ( Cherenkov Telescope Array Observatory ) project, which will create the world's largest network of telescopes for the detection

The ONCE is dedicating its lottery ticket for Sunday, June 29, to the 40th anniversary of the Instituto de Astrofísica de Canarias (IAC). Five and a half million coupons will spread the word about this anniversary throughout Spain, featuring an image of the Gran Telescopio Canarias (GTC or Grantecan), the world's largest optical-infrared telescope, located at the Roque de los Muchachos Observatory (La Palma). Since it began scientific operations in 2009, the GTC has become a symbol of the scientific and technical consolidation of the IAC and the Canary Islands Observatories (OCAN), and its
