    A distance of 13 Mpc resolves the claimed anomalies of the galaxy lacking dark matter
    The claimed detection of a diffuse galaxy lacking dark matter represents a possible challenge to our understanding of the properties of these galaxies and galaxy formation in general. The galaxy, already identified in photographic plates taken in the summer of 1976 at the UK 48-in Schmidt telescope, presents normal distance-independent properties (e.g. colour, velocity dispersion of its globular clusters). However, distance-dependent quantities are at odds with those of other similar galaxies, namely the luminosity function and sizes of its globular clusters, mass-to-light ratio, and dark

    Chile and Argentina feature in the next solar eclipse
    On July 2nd there will be a total eclipse of the sun which will touch land only in Chile, Argentina, and on the island of Oeno a small corral atol in the centre of the Pacific. This astronomical event will be broadcast live via the web sky-live.tv, with the collaboration of the Cerro Tololo Observatory (Chile), and STARS4ALL, a project in which the Instituto de Astrofísica de Canarias (IAC) is participating.

    Inauguration of the ARTEMIS telescope at the Teide Observatory
    This new telescope for finding Earth-like planets which may transit some of the smaller cooler stars in the solar neighbourhood joints the SPECULOOS network of 1m diameter telescopes which include the University of Liège (Belgium), Massachussetts Institute of Technology (MIT), of the US, and now the Instituto de Astrofísica de Canarias (IAC).

    New Earths discovered around a very small star
    An international team led by the University of Göttingen (Germany) with participation by researchers from the Instituto de Astrofísica de Canarias (IAC) have discovered, using the CARMENES high resolution spectrograph at the Calar Alto Observatory (Almería) two new planets like the Earth around one of the closest stars within our Galactic neighbourhood.

    Press release
    Tres alumnas del programa Canarias Masterclass comparten una jornada en el IAC
    (In Spanish only) El pasado 13 de junio, tres estudiantes de segundo de bachillerato, pertenecientes al programa Canarias Masterclass, visitaron la sede central del IAC en La Laguna para compartir una jornada laboral junto con profesionales de las diferentes áreas del Instituto. Las tres alumnas tienen intereses relacionados con la Física o la Astrofísica, y pudieron vivir durante un día cómo se trabaja en un centro de investigación puntero y conocer sus instalaciones.
