An international scientific team, including the Instituto de Astrofísica de Canarias (IAC), has detected distortions in the brightness of a galaxy's disc that could be explained by the gravitational effect of an unknown neighbouring galaxy. Named GTC-1, the satellite galaxy was discovered using ultra-deep images obtained with the OSIRIS camera of the Gran Telescopio Canarias, located at the Roque de los Muchachos Observatory in La Palma. The finding provides a possible explanation for a puzzle about way the light fades out at the edges of galaxy disks, a mystery that has bothered the

Using observations made with the Gran Telescopio Canarias (GTC) a study led from the Instituto de Astrofísica de Canarias (IAC) and the Universidad Complutense de Madrid (UCM) has confirmed that the asteroid 2023 FW14, discovered last year, is accompanying the red planet in its journey around the Sun, ahead of Mars and in the same orbit. With this new member, the group of Trojans which accompany Mars has increased in number to 17. But it shows differences in its orbit and chemical composition which may indicate that it is a captured asteroid, of a primitive type. The results are published in

9 institutions from 7 European countries today signed the documents for this organization, which will prepare the way towards the future construction of the European Solar Telescope (EST) One of the main aims of the EST is to improve our understanding of the Sun by observing its magnetic fields in unprecedented detail Representatives from 8 institutions in 7 European countries, among which are the Consejo Superior de Investigaciones Científicas (CSIC) and the Instituto de Astrofísica de Canarias (IAC) this morning in Santa Cruz de Tenerife, signed the founding documents of the Canary
