  • M87
    A team of astronomers has discovered that galaxies with an Active Galactic Nucleus (AGN) –hosting continuously growing black holes that emit large amounts of energy and radiation– may undergo a period of rapid star birth before shutting down completely. The research, conducted by astronomers from the Instituto de Astrofísica de Canarias (IAC), the University of Southampton and the Institute of Space Sciences, ICE (IEEC- CSIC) , was published in Monthly Notices of the Royal Astronomical Society: Letters. The Universe is filled with trillions of galaxies, each one comprising billions of stars

  • Some of the brightest Geminids that sky-live.tv's videomaker Daniel Padrón captured in just 30 minutes the night of Dec. 13 to 14 at the Teide Observatory of the Instituto de Astrofísica de Canarias. In the image, the European Space Agency's OGS telescope and the Teide volcano.
    During the nights of 12th and 13th of December we will enjoy the peak of the Geminid meteor shower. This will be broadcast live from the Teide Observatory (Tenerife) via the sky-live.tv channel, with the collaboration with the Energy Efficiency Labs (EELabs) project, of the Instituto de Astrofísica de Canarias (IAC). During the past decade the Geminids have always bid farewell to the year by producing over 100 meteors per hour (Zenith Hourly Rate, ZHR. In 2020 produce over 130 meteors/hour) which puts them in the annual front rank of meteor showers, together with the Perseids and the

  • GJ 367 b
    An international team, including researchers from the Instituto de Astrofísica de Canarias (IAC), has discovered an extrasolar planet with half the mass of the Earth that takes approximately eight hours to orbit its parent star, a red dwarf just under 31 light-years from Earth. Called GJ 367 b, it is one of the lightest among the nearly 5.000 exoplanets known today. With a diameter of just over 9000 kilometres, this sub-Earth is slightly larger than Mars. The discovery not only demonstrates that it is possible to precisely determine the event the smallest, least massive exoplanets, but also

  • V1298 Tau
    An international team of scientists, in which researchers from the Instituto de Astrofísica de Canarias (IAC) participate together with other institutions from Spain, Italy, Germany, Belgium, UK, and Mexico, has been able to measure the masses of the giant planets of the V1298 Tau system, just 20 million year old. Masses for such young giant planets had not been obtained previously, and this is the first evidence that these objects have already reached their final size at very early stages of their evolution. For this study they have used radial velocity measurements from the HARPS-N

  • Grupo Winter
    65 doctoral students and postgraduate researchers from 15 different countries participated, for 9 days, in the XXXII Canary Islands Winter School of Astrophysics, which this year was focused on clusters of galaxies, the largest gravitationally bound structures that we can observe in the Universe. Of the full complement of students, 55 were present at the school, while the other 10 followed the course on internet. As well as being one fo the first astrophysics meetings celebrated internationally with students present, this edition of the IAC Winter School was noteworthy for the highest

  • (Left) Location of target PNe on an image of the Andromeda galaxy (M31). (Right) Hertzsprung-Russell diagram showing the location of PNe central stars and the theoretical model tracks. The final and corresponding initial masses are indicated on the tracks. Note the remarkable clustering of the brightest PNe central stars (green squares) on the 1.5 Msun track.
    Planetary nebulae (PNe) are the ejecta of evolved low-intermediate mass stars present in all stellar systems. Perhaps the easiest thing to do when studying PNe in a galaxy is just counting how many of them appear with a given luminosity, the Planetary Nebula Luminosity Function (PNLF). Not surprisingly, just a few very bright, and many more fainter, PNe populate the PNLF. But, most surprisingly, the bright end bin of the PNLF has a remarkably constant cut-off value in all galaxies and stellar systems studied so far, both young and old, with just a mild, calibrateable dependence on
