Clues to the first stars may be hiding much closer to home than expected. An international team led by the Instituto de Astrofísica de Canarias (IAC) has detected potential chemical traces of the very first stars in the Universe within a neighboring galaxy. The setting for this discovery is NGC 1277, a well-known "relic" galaxy. While normal galaxies grow and transform by merging with others throughout their history, this compact system formed most of its stars very quickly in the early Universe and became frozen in time. Acting as a cosmic time capsule, this galaxy is perfect forAdvertised on -
An international team of astronomers, including researchers from the Instituto de Astrofísica de Canarias (IAC) and the Gran Telescopio Canarias (GTC), has observed a dramatic change in a supermassive black hole. Located about 10 billion light-years away, the object dimmed to roughly one-twentieth of its former brightness in just two decades — an extraordinarily short interval on cosmic timescales. The discovery was made within a collaborative observing framework linking Japan’s Subaru Telescope with the GTC in Spain’s Canary Islands at the Roque de los Muchachos Observatory, in La PalmaAdvertised on -
The members of the Comité Científico Internacional (CCI) of the Canary Islands Observatories met today on the island of La Palma. The ISC is the body established in the International Agreements that gave rise to the Canary Islands Observatories managed by the Instituto de Astrofísica de Canarias (IAC) and guarantees the effective participation of the User Institutions in decision-making regarding their use, maintenance and improvement. The meeting, held at the Hotel H10 Taburiente Playa, began with a minute's silence in memory of Professor Francisco Sánchez, founder of the IAC, whose legacyAdvertised on
