The Instituto de Astrofísica de Canarias (IAC) in collaboration with the University of Geneva (Switzerland), the University of Osaka (Japan), and the University of Zhejiang (China) has made a key contribution to a more precise measurement of the expansion of the Universe. This is because they have made an improvement in the precision of the calculation of the scale of the universe in its early stages using the analisis of the distribution of gas in intergalactic space, measurements which reach back to epochs between 10,000 and 12,000 million years ago. This result comes from the análisis of

During commissioning the Canary satellite ALISIO-1 proves its efficiency by observing phenomena in over 100 regions of the world The first Canary satellite, led by the Instituto de Astrofísica de Canarias (IAC), ALISIO-1, (an acronym for Advanced Land-Imaging Satellite for Infrared Observations) was launched into space on December 1st 2023 from the Vandenberg Airforce Base in California, and in only a few months has completed the commissioning phase, the verification on orbit that all its systems are working correctly. In this phase of verification the DRAGO-2 camera has been calibrated, and

A study led by researcher Laura Scholz, of the Instituto de Astrofísica de Canarias (IAC) has found, for the first time, observational evidence that the evolution and the properties of the galaxies are conditioned not only by the mass of the stars they contain, but aso by the effect of the dark matter halos which surround them. The results are published in the specialist journal Nature Astronomy. Dark matter comprises around 85% of all the matter in the Universe. Although ordinary matter absorbs, reflects and emits light, dark matter cannot be seen directly, which makes its detection
