    A “rebellious” exoplanet orbits in the opposite direction of its star
    Thanks to the NIRPS infrared spectrograph, built with the involvement of the Instituto de Astrofísica de Canarias , an international team led by the University of Geneva has been able to identify the unique orbit of the exoplanet GJ 3090 b. An international team, led by the University of Geneva (UNIGE) and including researchers from the Instituto de Astrofísica de Canarias (IAC), has determined the orbital configuration of the exoplanet GJ 3090 b using the NIRPS spectrograph, built with the participation of the IAC and installed on the 3.6-metre telescope at the La Silla Observatory (ESO

    Press release
    The IAC remains fully committed to the development of the Roque de los Muchachos Observatory following the TMT decision
    On 18 September 2026, the Instituto de Astrofísica de Canarias (IAC) and the Ministry of Science, Innovation and Universities (MICIU) received a communication from the Executive Director of the TMT International Observatory (TIO) stating that its partners had been unable to reach the consensus required to accept the financial offer presented by the Ministry on 29 July to begin construction of the Thirty Meter Telescope (TMT) at the Roque de los Muchachos Observatory (ORM) on the island of La Palma. The proposal envisaged financing of up to €1 billion: a contribution from the Centre for the

    The DESIRED electron temperature relations in star-forming regions of the local Universe
    H II regions are clouds of glowing, ionised gas associated with regions of recent star formation. By studying the light emitted by these regions, we can learn about their physical conditions and chemical composition, providing important clues about how stars and galaxies form and evolve. One of the key properties we need to know is the temperature of the gas. We can measure it from the emission lines of different chemical elements, which probe different parts of an H II region. However, it is not always possible to measure all these temperatures directly. In these cases, we need to estimate

    LST-1 and MAGIC Telescopes Shatter Distance Record for the Very High-Energy Blazar OP 313
    On 11 August, the CTAO LST Collaboration and the MAGIC Collaboration released remarkable findings from observations of OP 313, the most distant very high-energy blazar ever recorded. The paper, published in the journal Astronomy & Astrophysics , presents in-depth observations conducted with the prototype Large-Sized Telescope (LST-1) and the MAGIC telescopes at the Roque de los Muchachos Observatory in La Palma, Spain. This comprehensive study follows the discovery of the source at very high energies by the LST-1 in December 2023, announced, at that time, via an Astronomer's Telegram (ATel)
