Massive stars, those over ten times heavier than our Sun, are the conduits of most elements of the periodic table and drive the morphological and chemical makeup of their host galaxies. Yet the origin of the most luminous and hottest stars among them, called 'blue supergiants', has been debated for many decades. Blue supergiants are strange stars. First, they are observed in large numbers, despite conventional stellar physics expecting them to live only briefly. Second, they are typically found alone, despite most massive stars being born with companions. Third, the majority of them harbourAdvertised on -
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 beAdvertised on
