    RAFFAELLA MORGANTI: "The first image of a black hole was an important milestone for astrophysics"

    Radioastronomy is one of the branches of observational astrophysics which has experienced considerable growth in recent years. To study the universe at radio frequencies specific instruments: radiotelescopes, are designed. Among the most powerful is the ALMA telescope array in the Atacama Desert (Chile) and in the near future we will see the building of the Square Kilometre Array (SKA) in Australia and South Africa. Raffaella Morganti, a Senior Astronomer at ASTRON and Professor of Astronomy at the Kapteyn Institute of the University of Groningen in the Netherlands, has worked on these and

  • Astronomical Calendar 2020 with a GTC Image
    Astronomical Calendar 2020

    The Instituto de Astrofísica de Canarias (IAC), in collaboration with the Museum of Science and the Cosmos (MCC) of Museums of Tenerife, and the Gran Telescopio Canarias (GTC) has published, as it does every year, a calendar with important astronomical dates for the year 2020, in the format of a poster or a wall calendar (see the gallery). The picture which illustrates it is a photograph of the GTC at dawn, in the Roque de los Muchachos Observatory (Garafía, La Palma), taken by the astrophotographer Daniél López. Free copies of the calendar, on paper in poster format can be obtained from

    Cheops, an orbiting telescope to characterize exoplanets

    This telescope was launched this morning from the Kourou (French Guyana) base of the European Space Agency (ESA) to observe minute changes in the brightness of stars, and to analyze the density and the composition of the exoplanets in orbit around them. In this project, led by ESA and Switzerland, there are 21 scientific institutions from ten countries participating, among them two researchers from the Instituto de Astrofisica de Canarias (IAC). The aim of the Cheops telescope is to follow exoplanets already discovered to make precision analyses of their densities, which is an essential step

    Young stars found in the oldest and most massive galaxies in the universe

    Researchers from the Instituto de Astrofísica de Canarias (IAC) and the Istituto Nazionale di Astrofisica (INAF, Italy) have shown that massive early-type galaxies keep on forming stars, even though at a very slow rate. The results of this work, whose first author is the doctoral student at the IAC/ULL Núria Salvador-Rusiñol, are published today in the journal Nature Astronomy . Elliptical and lenticular galaxies (collectively called Early-Type galaxies) are the oldest galaxies in the Universe. They are also the most massive galaxies in the Universe, reaching up to 100 times the mass of the

  • Lluvia de estrellas. Gemínidas
    GEMÍNIDAS 2019: The big winter meteor shower!

    On the nights of 13th and 14th December we will be able to enjoy the maximum of the Geminids meteor shower. The event will be broadcast live from the Teide Observatory (Tenerife), via the sky-live TV channel, on the night of December 14th, with the collaboration of the European project EELabs. The Geminids, along with the Perseids, are the biggest meteor showers of the year. Reliable and punctual, the Geminids never fail. The activity during the last ten years has always reached over 100 meteors per hour (ZHR “Zenith hourly rate”) putting it in the top rank of the annual meteor showers. Each

    Sources of light which appear and disappear observed in the sky

    An international research team from the Institute de Astrofísica de Canarias (IAC) and the University of Stockholm have discovered around a hundred very red light sources which appear and disappear in a short time interval, according to an article published in the Astronomical Journal. The study began with a sample of 600 million objects imaged on the sky which date from the decade of the 1950’s, comparing them with a matching modern survey. The result was to identify up to 150,000 objects, which were not repeated in the two catalogues. In a preliminary study of these light sources 100
