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

The "Astronomy Education Adventure in the Canary Islands 2023" will take place in Tenerife from 17 to 21 July and will mainly focus on research on the Solar System and extrasolar planets, highlighting the work carried out at the IAC and the Observatories of the Canary Islands. The Instituto de Astrofísica de Canarias (IAC), together with other scientific and educational institutions, is organising the ninth edition of the "Astronomy Education Adventure in the Canary Islands" (AEACI). Under the title "Other Worlds", the latest discoveries and advances in research on extrasolar planets, the

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
