    Exploring the atmosphere of GJ 1132 b with CRIRES+
    The rocky planet GJ 1132 b, with Earth-like mass and radius, is a prime candidate for atmospheric studies. Previous observations with Hubble and JWST yielded conflicting results about its atmosphere. This study used three transit observations with the CRIRES+ instrument to search for He i, HCN, CH₄, and H₂O in GJ 1132 b's atmosphere. No clear atmospheric signals were detected, but upper limits for CH₄, HCN, and H₂O were established. The results suggest that if GJ 1132 b has an atmosphere, it is not dominated by hydrogen. The work highlights the challenges of detecting high molecular weight

    The Instituto de Astrofísica de Canarias hosts the Spanish ALMA Days 2025
    The Instituto de Astrofísica de Canarias (IAC) has been host to the Spanish ALMA Days 2025, which was held from 18th to 20th February in the IACTEC building in the Science and Technology Park at Las Mantecas (Tenerife). The aim of this event was to give information about the coming observation cycle of ALMA ( Atacama Large Millimetre/Submillimetre Array ) and to provide an overview of the data base of the telescope and its observing tools. In addition the scientific results of more than 10 years of observations were presented, and the future perspectives offered with the implementation of
