    Ending of the course for teachers “Get close to the Cosmos”
    For the fourth successive year the Instituto de Astrofísica de Canarias and the National Institute for Educational Technology and Teacher Training (INTEF), in collaboration with the International Menéndez Pelayo University (UIMP) has given teachers of secondary and pre-university education the opportunity to get to know the latest discoveries in astrophysics in a course given by professionals, thereby acquiring the tools for using them afterwards in the classroom.

    A study of the whole Sun
    The European Research Council (ERC) has awarded one of its prestigious “ERC Synergy Grants” to a team led by Fernando Moreno Insertis, researcher at the Instituto de Astrofísica de Canarias (IAC) and Professor at the University of La Laguna (ULL) as a member of a consortium of five European institutions.

    A planetesimal orbiting within the debris disc around a white dwarf star
    Numerous exoplanets have been detected around Sun-like stars. These stars end their lives as white dwarfs, which should inherit any surviving planetary systems. In fact, many white dwarf stars show signs of having accreted smaller bodies, implying that they may host planetary systems. A small number of these systems contain gaseous debris discs, visible through emission lines. Here, we report a stable 123.4-minute periodic variation in the strength and shape of the Ca II emission line profiles originating from the debris disc around the white dwarf SDSS J122859.93+104032.9. We used numerical

    A giant interstellar bubble being grown in the Andromeda galaxy
    The combination of a white dwarf mass close to the Chandrasekhar limit (1.4 solar masses) and a fast hydrogen accretion rate (10 -7 solar masses per year) from a companion star leads to frequent thermonuclear runaways in the accumulated envelope of gas on the white dwarf. These are known as nova eruptions and have recurrence times of years to decades. In this work we report that the recurrent nova with the shortest recurrence timescale known (approximately once a year), M31N 2008-12a in the Andromeda galaxy, is surrounded by a giant shell with a projected size of about 134 by 90 pc that is

    Amanar: under the same sky
    Today marks the official start of this outreach project in astronomy, which promotes scientific education and supports the young people and the teachers who live in the saharaui refugee camps. The activities of astronomical popularization and the visits to the Canary Observatories will start on July 20th, and will last until October, when an international team, with participation from the Instituto de Astrofísica de Canarias (IAC) will travel to the saharaui refugee camps near Tinduf, in Algeria. Amanar, which means The Pleiades” in Berber, is an astronomical outreach project to inspire the
