The existence of dark matter is likely one of the most perplexing problems facing the scientific community, and unraveling its nature has become one of the primary goals of modern physics. In simple terms, we do not know what dark matter is made of, despite accounting for 85% of all the matter in the Universe. A study led by the Instituto de Astrofísica de Canarias concludes that dark matter does not behave as described by the dominant paradigm, which states that dark matter particles only interact with each other and with ordinary matter through gravity. The IAC study reveals that dark

The Museo de la Ciencia y el Cosmos, part of the Organismo Autónomo de Museos y Centros del Cabildo de Tenerife, will host a conference by the astrophysicist and 2006 Nobel Laureate in Physics, John Mather, entitled ‘Unsolved mysteries of physics and astronomy’, on Friday 9th May. Mather receives this week the recognition as Doctor Honoris Causa of the Universidad de La Laguna (ULL) with the sponsorship of the researcher of the Instituto de Astrofísica de Canarias (IAC) and Doctor Honoris Causa of the ULL, John Beckman. Mather's lecture, which will be in English, will be presented by the

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
