A team of cosmologists from the Institute of Astrophysics of Andalusia (IAA-CSIC) and the Institute of Astrophysics of the Canary Islands (IAC) has obtained the most accurate census to date of the dark matter halos of the Universe. The work is based on the development of a new model, called GPS+, capable of predicting how many dark matter halos exist at each stage of cosmic history. In the universe, there are enormous invisible structures surrounding galaxies and galaxy clusters. These are dark matter halos, concentrations of matter that do not emit light and cannot be directly observed, but

The Instituto de Astrofísica de Canarias (IAC) is joining the Earth Hour, a global movement that, once a year, reminds us that nature is the planet’s life support and highlights the environmental emergency that requires collective action.

An international team, including a researcher from the Instituto de Astrofísica de Canarias (IAC), has obtained an incredible image of the planetary nebula NGC 1514 using the James Webb Space Telescope (JWST), revealing the nebula's spectacular dusty rings in unprecedented detail. NGC 1514 was one of the first nebulae to be studied by astronomer William Herschel, who noted that when viewed through his telescope (the biggest in the World at the time) the nebula looked like a fuzzy cloud somewhat similar in appearance to one of his other discoveries: the planet Neptune. The new images acquired
