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

The first satellite developed by the Instituto de Astrofísica de Canarias,, which was launched into space last December, has sent back its first images. The quality of the observations shows the perfect performance of its DRAGO-2 infrared camera. The pointing test of its laser optical communications module has also been successfully carried out, making it the first Spanish satellite to use this technology. Today, at a press conference, the first images obtained with the ALISIO-1 satellite (Advanced Land-Imaging Satellite for Infrared Observations), an Earth observation satellite whose

Between 27th August and 7th September the Shelios 2023 expedition tool a group of researchers and students at the south of Iceland and Greenland, where they set up two experiments to measure the natural darkness of the arctic night, and from where they broadcast the aurora borealis. Among the apparatus they installed is the autonomous MiNiO ( Meteo Nano Observatory) controller, developed by the Technological Institute for Renewable Energies (ITER), for the Interreg EELabs project, coordinated by the Instituto de Astrofísica de Canarias (IAC). As well as making people aware of the problems of
