"Telling light pollution from coast to coast": a nat’l outreach event for the World Environment Day

"Telling light pollution from coast to coast": a nat’l outreach event for the World Environment Day

eclipse

Almería, 2 June 2025

The event, coordinated by the Spanish National Research Council (CSIC), will bring together, on June 5th, 2025, experts in the field, who will simultaneously give 21 informative talks in 19 Spanish cities to raise awareness among the general public about this growing threat. Calar Alto Observatory participates in the fight against this environmental challenge with a talk open to the public at the Museum of Contemporary Spanish Realism (MuReC), in the city of Almeria, at 6 pm.

A new camera from Sevilla in Calar Alto to study Venus’ clouds

A new camera from Sevilla in Calar Alto to study Venus’ clouds

Almería, April 21st  2025

An ultra-fast infrared camera from Universidad de Sevilla has been installed on the Calar Alto Observatory 1.23-meter telescope to study in details the clouds on the Venus planet. The project, led by a researcher from Universidad de Sevilla, aims at understanding better the thick and complex Venusian atmosphere where hurricane-like winds are at play.

The new instrument, which can take up to 600 images per second, opens the near-infrared window for the 1.23 m telescope and will be available soon to study other planets and satellites in the Solar System, and exoplanets as well as extragalactic sources.

Four solar eclipses in three years in Spain: how to observe them easily and safely?

Four solar eclipses in three years in Spain: how to observe them easily and safely?

eclipseAlmeria, 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, the first 4K infrared camera for the European sky

PANIC, the first 4K infrared camera for the European sky

Almería, 20 March 2025

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.

Somos polvo de estrellas, buscando en el firmamento las respuestas que el universo tiene guardadas para nosotros. La astronomía es el arte de desvelar los secretos del cosmos, y cada noche, al observar el cielo, nos acercamos un poco más a nuestro lugar en el infinito.
