    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

    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

    DESI opens its 5.000 eyes to capture the colors of the Cosmos

    The new instrument, the result of an international collaboration of almost a hundred institutions, including the Instituto de Astrofísica de Canarias, has made its first trial observation. Designed to explore the mystery of dark energy, its installation is about to be completed at the Mayall telescope of the Kitt Peak Observatory in Arizona (United States).
