The Instituto de Astrofísica de Canarias (IAC) is one of the international researches centres which is following actively the asteroid 2024 YR4 which has been qualified by the United Nations (UN) as potentially dangerous, because it has a 1.5% probability of impacting the Earth during 2032.The asteroid was discovered in 2024 and has an estimated size of between 40 and 90 metres. Given these figures, the UN has activated the protocols of planetary defence to obtain more accurate estimates of the orbit, the size and the threat which might be presented by 2024 YR4. The protocols of the UN are

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
