  • International Scientific Committee (CCI) of the Canary Islands Observatories

    Members of the different institutions that make up the International Scientific Committee (CCI) of the Canary Islands Observatories met last Tuesday, 31 October, in the island of La Palma. The meeting was attended by Rafael Rebolo, Director of the Instituto de Astrofísica de Canarias (IAC), and Casiana Múñoz, Deputy Director of the IAC. The CCI is the committee created in the International Agreements that established the Canary Islands Observatories for an effective participation of the User Institutions in the adoption of decisions related to the use and improvement of the observatories

    The first Canary Earth Observation Satellite, belonging to the Instituto de Astrofísica de Canarias (IAC), has successfully passed all the pre-launch technical tests, and is on the way to the United States for launch from California before the end of the year. ALISIO-1 (Advanced Land-Imaging Satellite for Infrared Observations) is the first Canary satellite which will orbit the Earth, in the framework of the ALISIO space programme, led by the IAC and coordinated by the IACTEC-Space group. In 2018, the team gained its first success after the launch of an atmospheric sounding balloon with live

  • Mapa interactivo contaminación lumínica EELabs

    La Universidad de las Palmas de Gran Canaria y el Instituto de Astrofísica de Canarias han desarrollado un método para calibrar imágenes nocturnas de satélites a partir de medidas de redes de fotómetros nocturnos. El trabajo, financiado por el proyecto Interreg EELabs, está orientado a evaluar de forma más precisa la contaminación lumínica y su impacto en los ecosistemas naturales de la Macaronesia. Los datos están a disposición de la comunidad científica a través del portal del proyecto. Desde su inicio en 2020, el proyecto Interreg EELabs ha desplegado más de un centenar de sensores en las

  • Yesterday, 30 October 2023, from the telescope itself at the Roque de los Muchachos Observatory on the island of La Palma, the WEAVE instrument, a powerful state-of-the-art multi-fibre spectrograph, was publicly unveiled. The inauguration ceremony brought to La Palma the leaders of the science funding agencies from the partner countries of the Isaac Newton Group of Telescopes (ING), as well as a strong representation from the 500 members of the science teams and the organisations involved in the design and construction of WEAVE, making it the largest ever gathering of people inside the dome

  • Accretion disks around compact objects are expected to enter an unstable phase at high luminosity. One instability may occur when the radiation pressure generated by accretion modifies the disk viscosity, resulting in the cyclic depletion and refilling of the inner disk on short timescales. Such a scenario, however, has only been quantitatively verified for a single stellar-mass black hole. Although there are hints of these cycles in a few isolated cases, their apparent absence in the variable emission of most bright accreting neutron stars and black holes has been a continuing puzzle.

  • Pleiades Open Cluster

    After comparative studies of a sample of almost 50 open stellar clusters of different ages in the Milky Way, research led by the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) with collaboration by the Polytechnic University of Cartagena, shows that when these star clusters age they lose the majority of their less massive members. This result confirms that there are internal dynamical processes in open clusters caused by their long journeys through the Galaxy, which bring about the expulsion of these low mass stars. The study, published in the journal
