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

The Solar System research group at the Instituto de Astrofísica de Canarias (IAC) is participating in the international programme to keep a closet track of asteroid 2024 YR4. The aim is to determine its orbit with the highest possible precision before it stops being observable by ground based and satellite telescopes in April, and so improving our value of the probability that it will impact the Earth in 2032. In this context several telescopes of the Canary Observatories of the IAC are playing an outstanding role in this observing campaign: The Gran Telescopio Canarias (GTC) at the Roque de

La reconocida astrofísica Jocelyn Bell ha sido reconocida con la quinta estrella del Paseo de la Ciencia de Santa Cruz de La Palma, reconociendo su labor en defensa de la igualdad y los descubrimientos realizados. Un reconocimiento que ha sido simbólicamente entregado por el presidente del Cabildo de La Palma, Sergio Rodríguez, en un acto en el que ha participado la subdirectora del Instituto de Astrofísica de Canarias (IAC), Eva Villaver y el director del Festival Starmus, Garik Israelian. La subdirectora del IAC agradeció a Bell el trabajo científico realizado en toda su carrera y
