  • A snapshot from TESS of part of the southern sky showing the location of ν Indi
    TESS satellite dates an ancient collision with our galaxy

    From a single bright star in the constellation of Indus, an international team of scientists led by the University of Birmingham, with the participation of scientists from the Instituto de Astrofísica de Canarias (IAC), has revealed new insights about an ancient collision between our galaxy, the Milky Way, and another smaller galaxy called Gaia-Enceladus, early in its history. Nature Astronomy publishes these results today. This team adopted the novel approach of applying the forensic characterisation of a single ancient, bright star called ν Indi, visible from the southern hemisphere, as a

  • Meteoros registered at the Teide Observatory the 4th January 2107
    The Quadrantid meteor shower: start the year with a good wish

    This astronomical event will be broadcast live via the channel in the early hours of January 4th, with the collaboration of the European project EELabs. Together with the Geminids and the Perseids, this is the most intense meteor shower of the year. The three most spectacular meteor showers of the year are the Perseids (in August) the Geminids (in December) and the Quadrantids in the first week of January. Although the Perseids are the best known, the maximum is in a holiday period with mild night-time temperatures, the Geminids and the Quadrantids never let us down, with an

    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
