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

An international team of astronomers, including researchers from the Instituto de Astrofísica de Canarias (IAC), the University of Liège and collaborators in UK, Chile, the USA, and Europe, has discovered a transiting giant planet orbiting the smallest known star to host such a companion — a finding that defies current theories of planet formation. The host star, TOI-6894 , is a red dwarf with only 20% the mass of the Sun , typical of the most common stars in our galaxy. Until now, such low-mass stars were not thought capable of forming or retaining giant planets. But as published today in

The Technical Office for the Protection of the Quality of the Sky (OTPC) of the IAC is collaborating to advise about the implementation of energy efficiency and the reduction of light pollution in the port installations of general interest which belong to the public company Puertos Canarios. Specifically, the IAC has just issued a report which checks out the exterior lighting of the installations of the Port of las Nieves in Agaete (Gran Canaria), and in the coming months expects to carry out suitable tests in the Port of Vueltas in Valle Gran Rey (La Gomera) and the Port of Garachico
