While training with the Calar Alto 1.23 m telescope, a group of students from University College Dublin managed to observe the optical counterpart of a newly discovered transient event known as Gamma-Ray Burst, nearly three days after it violently exploded. This target of opportunity observation was key to coordinate observations with larger telescopes in Calar Alto and worldwide. This has allowed the students to significantly contribute to the process of building scientific evidence to reveal the true nature of this peculiar violent phenomenon.

A study based on observations from the CARMENES instrument has made it possible to gain deeper insight into the atmosphere of GJ 436 b, a Neptune-like exoplanet that orbits very close to a red dwarf and undergoes intense atmospheric loss.
The results reveal the presence of clouds in extremely high atmospheric layers and an exceptional metallicity, about 900 times higher than that of the Sun, significantly expanding our understanding of the evolution of this type of exoplanet.

Eloísa del Pino, presidenta del CSIC, ha visitado el observatorio de Calar Alto antes de celebrar, en Granada, el 50º aniversario del Instituto de Astrofísica de Andalucía (IAA-CSIC). El observatorio tiene al CSIC como cosocio desde 2005, además de la Junta de Andalucía desde 2019. En 2025, celebramos pues tanto los veinte años de la participación oficial del CSIC en Calar Alto como el medio siglo de existencia del instituto granadino.
Los 21 y 22 octubre 2025, una delegación del Consejo Superior de Investigaciones Científicas (CSIC), el mayor organismo público de investigación en España, ha visitado el Centro Astronómico Hispano en Andalucía (CAHA) en Calar Alto.
