The Instituto de Astrofísica de Canarias (IAC) invites the public to visit the Teide Observatory (Izaña, Tenerife) during the weekend of 21 and 22 June, coinciding with the week of the summer solstice. The activity is part of its Open Days, a free science outreach initiative organised by the Observatory itself together with the IAC's Scientific Communication and Culture Unit (UC3). Over two days, those attending will be able to tour some of the most important scientific facilities at the centre, learn how they work from the technical and research staff, and make live solar observations.

Massive stars in metal-poor galaxies often have close partners, just like the massive stars in our metal-rich Milky Way. This has been discovered by an international scientific team in which research staff from the Instituto de Aastrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL) participate. They used the European Very Large Telescope in Chile to monitor the velocity of massive stars in the Small Magellanic Cloud. The research is published in Nature Astronomy . For the past twenty years, astronomers have known that many massive stars in the metal-rich Milky Way have a
