An international scientific team, with the participation of researchers from the Instituto de Astrofísica de Canarias (IAC), has found a new world similar in size to our planet orbiting an ultra-cold red dwarf located about 55 light-years away. Observations from the SPECULOOS telescope network, which includes the ARTEMIS telescope at the Teide Observatory in Tenerife, have made this discovery possible. The Gran Telescopio Canarias (GTC), at the Roque de los Muchachos Observatory on La Palma, has also played a key role in confirming the discovery, providing some of the most accurate ground

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

The existence of dark matter is likely one of the most perplexing problems facing the scientific community, and unraveling its nature has become one of the primary goals of modern physics. In simple terms, we do not know what dark matter is made of, despite accounting for 85% of all the matter in the Universe. A study led by the Instituto de Astrofísica de Canarias concludes that dark matter does not behave as described by the dominant paradigm, which states that dark matter particles only interact with each other and with ordinary matter through gravity. The IAC study reveals that dark
