An international team of scientists, with participation by researchers at the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) have found a barred spiral galaxy, similar to the Milky Way, in the early universe, when it was only 15% as old as it is now. The galaxy, ceers-2112, is the most distant barred spiral observed, and its existence poses a challege to the current model of formation and evolution of galaxies. The discovery, made with the James Webb Space Telescope (JWST) is published in the journal Nature. In astrophysics studying the structure of galaxies

A study led by researcher Laura Scholz, of the Instituto de Astrofísica de Canarias (IAC) has found, for the first time, observational evidence that the evolution and the properties of the galaxies are conditioned not only by the mass of the stars they contain, but aso by the effect of the dark matter halos which surround them. The results are published in the specialist journal Nature Astronomy. Dark matter comprises around 85% of all the matter in the Universe. Although ordinary matter absorbs, reflects and emits light, dark matter cannot be seen directly, which makes its detection
