Almeria, March 27th, 2025
Four solar eclipses will take place in Spain over less than three years: one partial eclipse (March 2025), two total eclipses (August 2026 and 2027), and one annular eclipse (January 2028). The last two will be ideally visible in a good part of Andalusia. This exceptional series of spectacular phenomena will attract millions of national and international visitors. It is a great opportunity to raise public awareness of astronomy.
However, observing a solar eclipse without protection represents a serious danger to the human eye: you should NEVER look directly at the Sun without proper equipment! Casual sunglasses do not provide the necessary protection.
In this press release, Calar Alto Observatory issues simple recommendations so that everyone can safely enjoy the great spectacle of Nature that a solar eclipse represents, starting with the partial eclipse of March 29th of this year.

PANIC (PAnoramic Near-Infrared Camera for Calar Alto) is a wide-field near-infrared camera for the 2.2-meter telescope at Calar Alto Observatory, developed jointly by the Max-Planck-Institut für Astronomie (MPIA) in Heidelberg, Germany, and the Instituto de Astrofísica de Andalucía (IAA-CSIC) in Granada, Spain.
Its four original detectors have been replaced by a large monolithic HAWAII-4RG™ detector of 4096x4096 pixels or “4K” which provides a field of view of 26 × 26 arcminutes (nearly the apparent size of the full moon). PANIC covers the near-infrared wavelength range (from 0.8 to 2.5 microns), being a very versatile instrument that can be used to study clusters, galaxies, nebulae, stars, exoplanets, and even the smallest bodies of the Solar System.

Thanks to multiple observations performed at Calar Alto, a European research team, led from Centro de Astrobiología (INTA-CSIC) in Madrid, makes public the first planetary system discovered in the framework of the KOBE project.
KOBE uses data from the CARMENES instrument, mounted on the CAHA 3.5 m telescope, to monitor since 2021 about 50 orange dwarf stars, which are somewhat smaller and less hot than our Sun. Due to their characteristics, orange dwarf stars are el Dorado (sweet spot) of the search for life beyond the Solar System, and this first KOBE discovery paths the way to new ones.

A new research led from the Centro de Astrobiología in Madrid (CAB, INTA-CSIC) has revised a previous study from NASA that had claimed the discovery, by the transit method alone, of an exoplanet orbiting the star K2-399.
Using more complete observations, including those taken from Calar Alto with CARMENES, the new research concludes that the detected transits, those mini-eclipses, are not due to a planet but to a pair of red dwarf stars orbiting K2-399, while eclipsing each other, which perfectly mimics a typical exoplanetary transit. This case reminds us that revision based on new data, and where appropriate, correction of previous results, is the basis of the scientific method.
