The Vera C. Rubin Observatory, located in Chile, today released its first images of the universe, known in astronomy as an instrument's “first light”. This event marks the beginning of a project that will revolutionise our understanding of the universe over the next decade. Jointly funded by the US National Science Foundation (NSF) and the US Department of Energy (DOE), the Instituto de Astrofísica de Canarias (IAC) is participating, as part of a consortium of Spanish institutions, in its scientific exploitation and contributing observation time from the Gran Telescopio Canarias (GTC or

The new infrared spectrograph NIRPS, built with the participation of the Instituto de Astrofísica de Canarias (IAC) and installed on the 3.6-metre telescope at ESO’s La Silla Observatory in Chile, has achieved its first scientific results, with four articles published today in the journal Astronomy & Astrophysics and one more accepted for publication. The data confirm its ability to detect Earth-like planets in the infrared for the first time with a precision better than one metre per second. One of the papers, led by IAC researcher Alejandro Suárez Mascareño, confirms the presence of a

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
