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 Palma

One of the biggest recent surprises in astronomy is the discovery that most stars like the Sun harbor a planet between the size of Earth and Neptune within the orbit of Mercury — sizes and orbits absent from our solar system. These ‘ super-Earths' and ` sub-Neptunes’ are the galaxy's most common planets, but their formation has been shrouded in mystery. Now, an international team of astronomers has found a crucial missing link. By weighing four newborn planets in the V1298 Tau system, they've captured a rare snapshot of worlds in the process of transforming into the galaxy's most common

The International Scientific Committee (CCI) of the Canary Islands Observatories met this week in Bologna, Italy, to address the current status and future actions for the astronomical infrastructures managed by the Instituto de Astrofísica de Canarias (IAC). The CCI is the body established under the International Agreements that founded the Canary Islands Observatories. It ensures the effective participation of user institutions in decision-making regarding the use, maintenance, and improvement of these world-class scientific facilities.
