    The IAC once again celebrates its Astronomical Education Adventure in face-to-face format
    The eighth edition of the international summer school for teachers "Astronomy Education Adventure in the Canary Islands" will take place from 24 to 29 July in Tenerife and will focus on the relationship between Astronomy and the Sustainable Development Goals. The Instituto de Astrofísica de Canarias (IAC), together with other scientific and educational institutions, organises the eighth edition of the international school for teachers "Astronomy Education Adventure in the Canary Islands" (AEACI) which this year will be dedicated to "Astronomy for Sustainable Development" on the occasion of

    A new planet hunter starts its work
    Researchers at the Instituto de Astrofísica de Canarias (IAC) have participated in the development of NIRPS, an instrument recently installed on the 3.6m telescope at the European Southern Observatory (ESO), which is now hunting for exoplanets around the coolest stars in the Milky Way from the La Silla Observatory, in Chile. The Near InfraRed Planet Searcher (NIRPS) has successfully carried out its first observations. “This remarkable infrared instrument will help us to find the nearest habitable worlds to our Solar System” states René Doyon, the Director of the Institute for Exoplanetary

    Proton acceleration in thermonuclear nova explosions revealed by gamma rays
    Classical novae are cataclysmic binary star systems in which the matter of a companion star is accreted on a white dwarf. Accumulation of hydrogen in a layer eventually causes a thermonuclear explosion on the surface of the white dwarf, brightening the white dwarf to ~100.000 solar luminosities and triggering ejection of the accumulated matter. Novae provide the extreme conditions required to accelerate particles, electrons or protons, to high energies. Here we present the detection of gamma rays by the MAGIC telescopes from the 2021 outburst of RS Ophiuchi, a recurrent nova with a red giant

    Gliese 486 b: a Rosetta stone for the study of exoplanets
    An international scientific team , with the participation of the Institutito de Astrofísica de Canarias (IAC), has measured the mass and radius of an Earth-like exoplanet with unprecedented accuracy . The detailed analysis allows to make robust predictions on the structure and composition of its interior and atmosphere. The study is published in the journal Astronomy & Astrophysics. Since the first exoplanet around a solar-like star , 51 Pegasi b, was discovered in 1995, the astronomical community has continued to find new exoplanets that are less and less massive, closer and closer, and

    Two new rocky planets in the solar neighborhood
    An international scientific collaboration, in which the Instituto de Astrofísica de Canarias (IAC) participates, has discovered two new super-Earths orbiting a bright red dwarf star only 33 light-years away. Both objects are among the closest-known rocky planets yet found outside our solar system . The results are presented today at the American Astronomical Society (AAS) meeting in Pasadena (California, USA). Two new exoplanets, HD 260655 b and HD 260655 c, have been detected using NASA's Transiting Exoplanet Survey Satellite (TESS), a space telescope designed to look for planets in orbit

    Possible evidence of planet formation found in the Orion Nebula
    International research led by scientists at the Instituto de Astrofísica de Canarias (IAC) has shown the existence of solid sulphur compounds in HH514, a jet of gas coming from the centre of the Orion Nebula. The concentration of this chemical element could be related to the process of exoplanet formation. The researchers have used three of the most important optical telescopes in the world: the Very Large Telescope (VLT), the Gran Telescopio Canarias (GTC or Grantecan) and the Hubble Space Telescope (HST). The results are published in the scientific journal Monthly Notices of the Royal
