  • 2MASS J20395358+4222505

    An international team of astronomers, led by researchers from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), has found one of the most massive and luminous stars in our galaxy, behind a dense cloud of interstellar gas and dust. It is a supergiant, with a mass almost 50 times the mass of the Sun, with a radius almost 40 times the solar radius, and a luminosity approaching a million times that of our own star, and has been given the descriptor 2MASS J20395358+4222505. But its most disconcerting aspect for the researchers is a variation in its velocity of

    The gravitational force needed for the universe to evolve from when it was almost uniform, during the Big Bang, until galaxies, stars, and planets were formed is provided by the “dark matter”. But in spite of the essential role of this basic component, which is estimated to make up some 80% of the matter in the universe, scientists know virtually nothing about its nature, behaviour, and composition, which is one of the main challenges in current physics and cosmology. Aiming to give answers to these questions the researcher Diego Blas, Senior Lecturer in the Department of Physics of King’s

  • ALMA cuásar

    Cristina Ramos Almeida, a researcher at the Instituto de Astrofísica de Canarias (IAC), has led research which used data from the ALMA telescope in Chile to understand how supermassive black holes impact the host galaxies they inhabit. The results are published today in the journal Astronomy & Astrophysics.

  • Abell 370

    A team of researchers from the cosmology group at the Instituto de Astrofísica de Canarias has obtained one of the most accurate measurements of the masses of clusters of galaxies, and of their relation with the amount of hot gas in these clusters. To do this they have studied the dynamics of the galaxies in 570 clusters selected from the catalogue produced by the Planck satellite (ESA). This study has been produced during four years of work, in which over 10,000 spectra have been obtained with the Telescopio Nazionale Galileo (TNG) and the Gran Telescopio Canarias (GTC) at the Roque de los

  • Proxima Centauri Planets

    An international team of astronomers, co-led by researchers from the Instituto de Astrofísica de Canarias (IAC), has confirmed the presence of a new planet orbiting Proxima Centauri, the closest star to the Solar System. It is the third planet detected in this star and one of the lowest mass planets ever discovered, with only a quarter of the mass of the Earth. The study, published today in the journal Astronomy & Astrophysics, uses observations made with the ESPRESSO spectrograph on the Very Large Telescope (VLT) at the European Southern Observatory (ESO) in Chile. Proxima Centauri is the

  • The Instituto de Astrofísica de Canarias (IAC), which has 94 female researchers and engineers, consolidates its commitment to gender equality by participating in more than ten actions to join this February 11. Among the aims of commemorating this day are the promotion of scientific and technological vocations among girls and young women and the visibility of the role of women in the development of science. In 2015 the General Assembly of the United Nations proclaimed 11th February as The Day of Women and Girls in Science. The aim of this date is to promote the access, the full participation
