    Astronomy and Literature, together again in La Palma

    In the III Hispano-American Writers’ Festival, which is being celebrated in Los Llanos de Aridane (La Palma), three authors and two astrophysicists participated yesterday, Thursday, in a panel discussion on the theme “Looking at what no longer exists”. During the morning, a small group of those invited to the Festival, in which the Instituto de Astrofísica de Canarias is collaborating, visited the Roque de Los Muchachos Observatory in Garafía, satisfying the necessary health and security measures against COVID-19.

    TESS, Spitzer and the GTC detect a planet orbiting a white dwarf for the first time

    With data from NASA’s TESS satellite, from the now retired Spitzer Space Telescope, and the Gran Telescopio Canarias (GTC) an international team of astronomers, with participation from the Instituto de Astrofísica de Canarias (IAC) has detected what appears to be an intact planet in orbit around a white dwarf, the dense remains of a star similar to the Sun , and only 40 % bigger in diameter than the Earth. This finding is published today in Nature magazine.

  • Photometers at the Teide Observatory
    Natural darkness to preserve night-time ecosystems

    After several months of waiting, this summer the EELabs project, led by the Instituto de Astrofísica de Canarias, has started to deploy its first network of photometers.

  • Teide 1 en el cúmulo de las Pléyades
    25th anniversary of the discovery of the first brown dwarf

    It is 25 years, now, since the astrophysicists Rafael Rebolo, María Rosa Zapatero-Osorio and Eduardo Marín announced the discovery of the first confirmed brown dwarf, Teide 1. It is in the Pleiades star cluster, and it is named after the Teide Observatory, from where it was observed for the first time with the Spanish IAC-80 telescope. It is one of the scientific landmarks with the greatest international impact obtained by the Instituto de Astrofísica de Canarias.

    The IAC is collaborating again with the Spanish-American Writers’ Festival in La Palma

    The Instituto de Astrofísica de Canarias (IAC) will be collaborating for the third successive year with the Spanish-American Writers’ Festival which will be celebrated from September 14th to 19th in Los Llanos de Aridane (La Palma). The programme of this third edition, in which almost 40 writers and a small group of meta-writers (editors, journalists and critics) will participate, will consist of 35 sessions. Among them we can pick out panel sessions on a variety of themes, autographs of examples by some of the authors involved, and activities aimed at the younger generation whose schools

    The presence of resonating cavities above sunspots has been confirmed

    An international team of researchers, led by the Instituto de Astrofísica de Canarias (IAC), has confirmed the existence of resonant cavities above sunspots. These results, recently published in two articles in the journals Nature Astronomy and The Astrophysical Journal Letters, have settled a debate lasting several decades about the nature of the waves in the active regions of the Sun. Sunspots are darker regions which often appear on the Sun’s surface. They are caused by strong concentrations of magnetic field, and can be as big as the Earth, or even much bigger. From the end of the 1960’s
