An international study led by Almudena Prieto, a researcher at the Instituto de Astrofísica de Canarias (IAC) has found places where new stars are forming, as faint star clusters, around the centre of an evolved galaxy. This is the first time that young populations of stars have been picked out and dated in this type of galaxies dominated by very old stars, which can be called “rejuvenated old galaxies”. The research has combined observations from various telescopes, both ground based and space based, and has used innovative techniques of data analysis. The results are published in the

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 PLATO (PLAnetary Transits and Oscillations of Stars) space mission, led by the European Space Agency (ESA), has recently completed one of the most delicate phases of its development: the integration of its main components, the 26 scientific cameras and the service module that houses all the instrument's acquisition, processing, and control electronics. This stage, carried out at the facilities of the aerospace company OHB in Germany, marks a fundamental step toward the launch scheduled for December 2026 from French Guiana aboard an Ariane 6 rocket. “Almost eight years after ESA gave the
