The Instituto de Astrofísica de Canarias (IAC), through IACTEC-Space, is participating this week in Space Tech Expo Europe, the largest space industry trade fair on the continent, held in Bremen from November 18 to 20. The team is located in the Spain Space pavilion, alongside the Canary Islands Aerospace Strategy (EAC), to showcase the technological developments of the CELESTE laboratories and strengthen international collaborations in the space sector. The I nstituto de Astrofísica de Canarias (IAC) is participating once again in Space Tech Expo Europe, the leading event for the space

This Saturday, 29 March 2025, the Instituto de Astrofísica de Canarias (IAC) was able to follow the partial solar eclipse from the Teide Observatory in Tenerife. Although subtle to the naked eye, this eclipse was used by the IAC's outreach team to raise awareness of the phenomenon among a group of people from the ‘Friends of the IAC’ programme and IAC staff. At the same time, an observation was also made from the IAC Headquarters in La Laguna, which could be seen live on the centre's YouTube channel. The eclipse began at 09:14 UT and ended at 10:56 UT, with its maximum at 10:03 UT. For just

A new study published in Astronomy & Astrophysics unveils a powerful way to determine the size of dark matter haloes—the massive, invisible structures that host galaxies—by simply measuring how large galaxies appear in deep astronomical images. Researchers Ignacio Trujillo and Claudio Dalla Vecchia, from the Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL), demonstrate that galaxy size can serve as a precise proxy for halo size, offering measurements up to six times more accurate than previous methods. Using the cutting-edge EAGLE cosmological simulations
