    A challenge to models of star-formation truncation in massive galaxies

    An international study published in Nature Astronomy, in which the Instituto de Astrofísica de Canarias (IAC) is a participant, suggests that the feedback winds do not have a direct impact on braking the formation of stars in massive galaxies, and attributes the process to other events such as ejection by huge tides caused when galaxies merge.

    Quadrantids 2021: our best wishes for the start of a new year

    This astronomical event will be broadcast live in the early hours of January 3rd from the Canary Observatories, via the channel, with the collaboration of the European Project Interreg EELabs and the Innovation Service of the Cabildo of the Island of La Palma. After the impressive data of the activity of the 2020 Geminids (the last major meteor shower of the year) the expectations for the Quadrantids are very high, even though this time the Moon will make it hard to see the fainter meteors. Usually the Geminids and the Quadrantids show activity approaching 100 meteors per hour

    2021 Astronomical Calendars

    The Outreach and Press Unit (UC3) of the Instituto de Astrofísica de Canarias (IAC), with the collaboration of Álex Oscoz Abad and the IAC Astrophotography Group (, has published as in previous years an astronomical wall calendar with astronomical ephemeris for the year 2021, which can be consulted and downloaded in digital format. The images that illustrate it have been obtained by Pedro A. González Morales and Jorge A. Pérez Prieto. This calendar joins another published in poster format illustrated with the image of the Heart Nebula. Both calendars can be

    MUTANT, the tool in PROMISSE to characterize biological tissues at different depths

    The programme of IACTEC-Medical Technology of the Instituto de Astrofísica de Canarias has developed a multifrequency microwave system called PROMISSE (PROtotype MIcrowave System for Subcutaneous anomalieEs) to characterize biological tissues at different depths. This project, whose origin is the aim of transferring astrophysical technology to the biomedical field, is part of the programme of Medical Technology within IACTEC, the area of technological and business collaboration of the Instituto de Astrofísica de Canarias (IAC), with the economic (Training Programme) and infrastructure
