Gravity has shaped our cosmos. Its attractive influence turned tiny differences in the amount of matter present in the early universe into the sprawling strands of galaxies we see today. A new study using data from the Dark Energy Spectroscopic Instrument (DESI) has traced how this cosmic structure grew over the past 11 billion years, providing the most precise test to date of gravity at very large scales. DESI is an international collaboration of more than 900 researchers, included the Instituto de Astrofísica de Canarias (IAC), from over 70 institutions around the world and is managed by

An international team, led by a student from Instituto de Astrofísica de Canarias (IAC), has detected a super-Earth orbiting in the habitable zone of GJ 3998, a nearby red dwarf located 59 ly away. The new planet, named GJ 3998 d, is the third planet found in the system. ‘GJ 3998 d is a welcome addition to the planetary census of our cosmic neighbourhood’, states Atanas Stefanov, a "La Caixa" funded PhD student at the IAC and the University of La Laguna (ULL) and the study’s lead author, published in Astronomy & Astrophysics . 'This super-Earth appears to be in the habitable zone of one of

A new citizen science project launched today by the European Space Agency (ESA) and the Euclid Consortium, in collaboration with the Zooniverse platform, will enable volunteers from around the world to identify the shapes of millions of galaxies in images taken by ESA's Euclid space telescope. The aim of the initiative is to train deep AI neural networks to build the largest morphology catalogue to date. In November 2023 and May 2024, the world got its first glimpse at the quality of Euclid’s images, targeting a variety of sources, from nearby nebulas to distant clusters of galaxies. And
