An international team led by the Institute of Astrophysics of Andalusia (IAA-CSIC) has provided the first conclusive evidence of a planet’s influence on the behavior of its star. Observations conducted largely with the CARMENES instrument at Calar Alto Observatory have made it possible to detect and estimate the strength of the magnetic field of the exoplanet GJ 436 b, opening a new avenue for studying the habitability of planets outside the Solar System.

The Leibniz Institute for Astrophysics Potsdam (AIP) and the Calar Alto Observatory de Calar Alto celebrate the 25th anniversary of the PMAS instrument (Potsdam Multi-Aperture Spectrophotometer) at the 3.5-meter telescope. Nowadays, PMAS remains a highly competitive integral field spectrograph and it is the most productive visitor instrument at the observatory, approaching the 500 publications based on PMAS data.

A new study from the CAVITY project analyzes, with an unprecedented level of detail, how the cosmic environment influences the evolution of the galaxies and finds that galaxies located in cosmic voids better preserve their gas and maintain more active star formation, especially in their outer regions.

The Calar Alto Observatory is renewing the instrumentation of its 1.23-meter telescope with the commissioning of a new camera based on sCMOS technology, which offers a wide field of view and a high sensitivity while capturing images at high speed.
This camera, funded by the Spanish Ministry of Science, Innovation, and Universities through the State Research Agency (reference EQC2024-008783-P), ensures that the 1.23-meter telescope—the first installed at the observatory in 1975 and upgraded for remote operation—remains highly competitive.
