    Experts debate in La Palma the future of the European research infrastructures

    For three days some 120 people met in Los Cancajos (La Palma) to participate in a workshop to exchange experiences, organized by the European Strategic Forum on Research Infrastructure (ESFRI). As well as discussing the European policies and initiatives in this area, the participants could get to know, at close range, the Roque de los Muchachos Observatory, and two of the projects, with major participation by the Instituto de Astrofísica de Canarias, which comprise part of the ESFRI Roadmap: The CTA array and the future European Solar Telescope (EST).

    Direct broadcast of the transit of Mercury

    Next Monday, November 11th, it will be possible to follow the transit of the planet Mercury across the face of the Sun from the Canary Island Observatories, from 12:36 p.m. to 18:04, on the channel YouTube IAC vídeos, of the Institute de Astrofísica de Canarias. A transit is defined as the passage of one astronomical object in front of another, so that the nearer occults a part of the surface of the farther. Only the inner planets (Marcury and Venus) can transit the Sun, from our viewpoint on Earth. In any century there are 13 transits of Mercury and the following transit will not occur

    Mercury passes across the face of the Sun for the fourth time in the present century

    The transit of the planet will take place next Monday, November 11, from 12: 36h to 18: 04h. It will last almost five and a half hours, and will be broadcast entirely and live from the Canary Islands Observatories. Transits of the Inner Planets - Venus and Mercury - are rarer than the eclipses of Sun and Moon. On average we will have 13 transits of Mercury per century. The last transit of Venus was June 2012. We had transits of Mercury in the years 2003, 2006 and 2016 and the next one will not occur until 2032. Few readers of this article will have seen Mercury, a very small planet. Ganymede

    The Consul of Japan in the Canary Islands visits the IAC

    The Consul of Japan in the Canary Islands Yoshihiro Miwa and his wife Ruriko Miwa recently visited the facilities of the Instituto de Astrofísica de Canarias (IAC) in La Laguna and the Observatorio del Teide in order to know the work on research and technological development carried out in this center of scientific excellence, as well as current and future collaborative projects with the Japanese country. In the OT they could get to know some of its main telescopes such as GREGOR, currently the largest solar telescope in Europe; the QUIJOTE experiment, dedicated to the characterisation of

    The early sequence of events that shaped the Milky Way

    Among the myriad discoveries presented in the second data release of the Gaia mission, there was an enigmatic color-magnitude diagram (CMD) of Milky Way halo stars, showing a striking double (blue/red) sequence. The blue sequence was linked to a major merger that our Galaxy experienced early in its history (Gaia-Enceladus). The origin of the red sequence was unclear, and it was generally associated, because of its chemical composition, with the Milky Way thick disk. However, the lack of accurate ages precluded a clear understanding of its nature. We compared this double-sequenced observed
