The first stars to form after the Big Bang and the Dark Era were very massive and played a leading role during the reionization epoch. From that moment onwards photons could travel unhindered in space, bringing us information about distant objects. The main difference between the first stars and those seen at present is that the former were formed solely from hydrogen and helium, in the absence of metals. Metal-poor massive stars are therefore fundamental to our understanding of the early stages of the Universe. New observations with the Gran Telescopio CANARIAS(GTC) take us a step closer to understanding stars in the early Universe. This work has been published in the journal Astronomy & Astrophysics.

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

After a break of 4 years, on June 23rd and 24th the Teide Observatory will be celebrating its Open Days. This activity is free; its aim is to bring some knowledge of astronomy to the general public, including those people who happen to be visiting the island on those two days. To make a visit it is essential to register using a special form before June 16th. In this year’s edition the activity will be guided, and 9 points of interest will be visited, one every 20 minutes, so that the complete visit should take 3 hours, from 10:00 to 13:00 for the morning session, and from 16:00 to 19:00 for
