A team of International astronomers, led by members of the Instituto de Astrofísica de Canarias, has measured for the first time the mass of an ultra-diffuse galaxy using the Gran Telescopio CANARIAS (GTC)

This morning before dawn, Venus “hid” behind the Moon for about an hour as seen from the Canaries. The occultation began, in the islands, at 07:27:23 local time (an hour later in the Peninsula) and not until 08:28:01 did it reappear on to the right of the lunar disc. The Teide Observatory, at Izaña (Tenerife), was a privileged place to enjoy the occultation due to its clear, virtually cloudless sky. A team from the Instituto de Astrofísica de Canarias (IAC), comprising the astrophysicist and popularizer Alfred Rosenberg and the astronomical photographer Daniél López, went up to the

Professor Klaus von Klitzing, Nobel Laureate in Physics, visited the Instituto de Astrofísica de Canarias (IAC), in La Laguna, and Teide Observatory on Monday at Izaña (Tenerife). During his tour at the IAC headquarters, he was guided by the director of the Institute, Rafael Rebolo, and other researchers, through the Instrumentation area. He was enthusiastic about EMIR, the forthcoming instrument to be installed on Gran Telescopio CANARIAS (GTC).

Sited at the Roque de los Muchachos Observatory, it will be the biggest and most rapid telescope in its class, as well as having the highest level of technology

Researchers at the Instituto de Astrofísica de Canarias (IAC) have produced a review article giving the most recent results in this area of solar physics.
