  • Material exógeno Ryugu y Bennu
    Exogeneous material found on the surface of asteroids Ryugu and Bennu

    The two near-Earth asteroids Ryugu and Bennu, primary targets of the Hayabusa2 (JAXA) and OSIRIS-REx (NASA) space missions, keep surprising us. In two companion papers presented in Nature Astronomy, researchers have found exogenous bright material scattered across the asteroids’ surfaces. Members of the Solar System Group of the Instituto de Astrofísica de Canarias (IAC) have contributed to this discovery, in particular Dr. Eri Tatsumi, who is the first author of the paper presenting findings on Ryugu (Hayabusa2).

    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.

  • 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.
