Two to tango: rare dwarf-dwarf merger observed in a cosmic void environment

Two to tango: rare dwarf-dwarf merger observed in a cosmic void environment

eclipseAlmería, 16 June 2025

In the framework of the CAVITY project, an international team of researchers have studied in detail a remarkable couple of dwarf galaxies “dancing with each other” inside an unpopulated area of the Universe. This uncommon pair of low-mass galaxies merging “in the middle of nowhere”, near the center of a cosmic void, offers a unique view of one-on-one interactions and of the evolution of galaxies located in very low density environments.

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.

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.
