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

International research led by the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) has found the first evidence of a massive galaxy with no dark matter. The result is a challenge to the current standard model of cosmology. The study is published in the specialized journal Astronomy and Astrophysics. A team of scientists, led by the researcher at the IAC and the University of La Laguna (ULL) Sebastién Comerón, has found that the galaxy NGC 1277 does not contain dark matter.This is the first time that a massive galaxy (it has a mass several times that of the

The first test images from its two instruments show its potential for achieving its scientific goals. These images will be used to check the instruments and to see how Euclid can be adjusted and fine tuned for best performance. The European Space Agency (ESA)’s Euclid mission, in which the Instituto de Astrofísica de Canarias (IAC) is participating, will produce the biggest and most accurate 3D map of the universe. Euclid’s two instruments VIS (VISible instrument) and NISP (Near Infrared Spectrometer and Photometer) have taken their first test images. The results indicated that this space
