    Next Friday, September 23nd, at 01:04 UT the Earth will be at a specific point in its orbit round the Sun: the September equinox. The September and March equinoxes are the only days in the year when the Sun rises exactly in the east and sets exactly in the west, across the whole planet. In practical terms the days at both the vernal and the autumnal equinoxes are divided equally into daytime and night-time, with each lasting approximately 12 hours. In fact the literal meaning of the word equinox, is “equal night” and comes from the latin word aequinoctium. Live from the Dolmen of Magacela

  • AMANAR en el Museo de la Ciencia y el Cosmos

    Saharaui children from the programme “Holidays in Peace 2022” and their hosting families enjoyed the astronomical outreach activities and visited the Museum of Science and the Cosmos and the IAC Headquarters in Tenerife. On September 2nd the Instituto de Astrofísica de Canarias (IAC) and the Canary Association for Friendship with the Sahraui People (ACAPS), in collaboration with the Museum of Science and the Cosmos (MCC, Museums of Tenerife), organized a day of outreach activities for the Saharaui children and for their host families in Tenerife, in the programme “Holidays in Peace”.

  • Binary milisecond pulsar

    A team of researchers from the Instituto de Astrofísica de Canarias (IAC), the University of Manchester and the Norwegian University of Science and Technology have detected an anomalously high lithium abundance in the atmosphere of the companion star of a binary millisecond pulsar. The lithium abundance is higher compared to stars with the same effective temperature and high-metallicity stars and so the study provides unambiguous evidence for fresh lithium production. Lithium is a fragile element and in stars similar to the Sun it is gradually destroyed in the interiors via low-temperature

  • The visit has generated new ideas in common, and has opened the way for collaboration on new international projects, especially, in the field of space domain awareness. Last Thursday, 8th September, a delegation of scientists and upper management from the University of Warwick, together with representatives from the Japanese Space Agency (JAXA) and the Instituto de Astrofísica de Canarias (IAAC) visited the scientific instruments which the University has installed at the ORM (La Palma). The group went to the Visitors’ Centre of the ORM, and attended a technical session in it auditórium

  • Strange landscape of a water world

    Research led by the University of Chicago and the Instituto de Astrofísica de Canarias (IAC) has shown the existence of exoplanets with water and rock around type M dwarf stars, which are the most common in the Galaxy. The results are published in the prestigious journal Science. A detailed analysis of the masses and the radii of all 43 known exoplanets around M stars, which make up 80% of the stars in the Milky Way, has led to a surprising discovery, entirely led by the researchers Rafael Luque, of the University of Chicago and the Instituto de Astrofísica de Andalucía (IAA-CSIC) and Enric

  • BL Lac

    The international collaboration Whole Earth Blazar Telescope (WEBT), in which researchers from the Instituto de Astrofísica de Canarias (IAC) participate, has discovered rapid and quasi-periodic variations in the observed brightness of the blazar BL Lacertae, located about a billion light-years away. These changes were observed during a strong outburst in 2020 and their origin is associated with a jet of high-energy particles. The study has used data from space satellites combined with observations from ground-based infrastructures, including the Teide Observatory (OT) and the Roque de los
