A study carried out by a team of researchers at the Instituto de Astrofísica de Canarias (IAC) has shown that an unusual thin structure of stars, recently discovered by the Hubble Space Telescope, could be a galaxy seen edge-on. This finding goes against the original interpretation in which a fleeing supermassive black hole was leaving a trail of stars in its wake. The new interpretation is published in the journal Astronomy and Astrophysics Letters. A mysterious trail of stars formed eight thousand million years ago and recently discovered by the Hubble Space Telescope has been a challenge

During commissioning the Canary satellite ALISIO-1 proves its efficiency by observing phenomena in over 100 regions of the world The first Canary satellite, led by the Instituto de Astrofísica de Canarias (IAC), ALISIO-1, (an acronym for Advanced Land-Imaging Satellite for Infrared Observations) was launched into space on December 1st 2023 from the Vandenberg Airforce Base in California, and in only a few months has completed the commissioning phase, the verification on orbit that all its systems are working correctly. In this phase of verification the DRAGO-2 camera has been calibrated, and

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
