An observationally based study, led by Martín López Corredoira, researcher at the Instituto de Astrofísica de Canarias (IAC) has found that certain very distant massive galaxies appear to be older than the limit set by standard cosmology. The study, published in The Astrophysical Journal, is based on the analysis of data recently obtained by the James Webb Space Telescope of galaxies that existed when the universe was only between 4% and 5% of its present age, according to the accepted standard model of cosmology. The researchers infer that the mean age of some of these galaxies would not be

The distribution of planets in the over five thousand distant solar systems discovered to date forms a complex puzzle. There is a region in the planetary orbit graph, known as the " Neptunian desert", where very few Neptune-like planets with orbits of between two and four days period around their star have been recorded to date. Now, a scientific team led by the Instituto de Astrofísica de Canarias (IAC) and the Instituto de Astrofísica de Andalucía-Consejo Superior de Investigaciones Científicas (IAA-CSIC) , using a novel technique, new planets around red dwarf stars located precisely in

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
