    The phosphorus that came from the stars

    All chemical elements in the Universe (except for H and most of the He) have been made in stellar interiors. But among those elements, the ones that allowed to build life such as we find on Earth are of particular interest (carbon, nitrogen, oxygen, sulphur and phosphorus). However, the stellar origin of phosphorus (P) is still unknown as none of the current models of Galactic chemical evolution can explain all the phosphorus we observe in the Galaxy and notably in our Solar System, highlighting a still lacking phosphorus source. In this work we report the discovery of stars very rich in

    The Perseids 2020

    On the night of 12th to 13th August we will be able to enjoy the maximum of the Perseids. This will be broadcast live, from the Teide Observatory (Tenerife) and from the Roque de los Muchachos Observatory (La Palma) on the channel on the night of August 12th, with the collaboration of the Energy Efficiency Laboratories (EELabs) project of the Instituto de Astrofísica de Canarias (IAC) and of the Program of Astronomy Outreach / SODECAM - Service for Innovation of the Cabildo of the Island of La Palma.

    Stars rich in phosphorus: seeds of life in the universe

    The journal Nature Communications today is publishing the discovery of a new type of stars, very rich in phosphorus, which could help to explain the origin of this chemical element in our Galaxy. This achievement has been made by astronomers of the Instituto de Astrofísica de Canarias (IAC) and researchers in computer science from the Centre for Research in Information and Communication Technology (CITIC) at the University of La Coruña (Galicia).

    Communiqué from the IAC. Telescopes of the ASTRI project

    The Teide Observatory (OT) is situated in the Nature Park of the High Forest. The National Institute of Astrophysics (INAF) of Italy (one of the signatories of the International Agreement of the Canary Observatories) in 2019 asked the IAC to explore the viability of an installation of Cherenkov telescopes (project ASTRI) in the OT. This project, if it comes to fruition, will be completely financed by Italy and will comprise the most advanced astrophysical installation of the Teide Observatory in the last 30 years. It will also provide observations of the internal structure of the Teide

    Differences between the discs of active and non-active galaxies detected for the first time

    A study led by researchers at the Instituto de Astrofísica de Canarias (IAC), making comparison between the discs of several pairs of spiral galaxies, active and non-active, concludes that in the discs of the former the rotational motion of the stars is of greater importance. This study, just accepted for publication in Astronomy & Astrophysics Letters, is the first evidence for large scale dynamical differences between active and non-active galaxies in the local universe. The astronomers participating are from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna
