The CAVITY international project, led from the University of Granada and based on three-dimensional (3D) images taken at Calar Alto, publishes a sample of 100 galaxies located in the so-called "voids", the most uninhabited areas of the Universe. These galaxies represent a pristine population, a reference sample for multiple cosmological studies.
The two-dimensional (2D) spectra obtained with the PMAS instrument on the 3.5 m telescope for CAVITY are made freely available to the public today at https://cavity.caha.es. CAVITY is one of three major ongoing legacy programs at Calar Alto, the largest optical observatory on the Old Continent.

El Observatorio de Calar Alto recibe a representantes de Gobierno, CSIC, Junta, Diputación y alcaldías de Almería
El Centro Astronómico Hispano en Andalucía, A.I.E. (Calar Alto) ha sido objeto hoy de una visita con la asistencia de diversas autoridades de la provincia de Almería, en un evento que ha permitido dar a conocer las instalaciones y proyectos en los que se trabaja desde esta instalación científica a la sociedad almeriense.
En este sentido, a lo largo de la jornada se ha contado con la presencia de representantes provinciales del Gobierno de España, la Junta de Andalucía, la Universidad de Almería y de los Ayuntamientos de Gérgal, Bacares y Serón. En concreto, han asistido José María Martín Fernández, Subdelegado del Gobierno de España en Almería; Margarita Paneque Sosa, Delegada del Consejo Superior de Investigaciones Científicas (CSIC) en Andalucía; Aránzazu Martín Moya, Delegada de Gobierno de la Junta de Andalucía en Almería; Dolores Martínez Utrera, Delegada Territorial de Fomento de la Junta de Andalucía en Almería; Francisco Alonso Martínez, Delegado Territorial de Desarrollo Educativo de la Junta de Andalucía en Almería; Antonio Jesús Rodríguez Segura, Diputado Provincial de Fomento e Infraestructuras; José Joaquín Céspedes Lorente, Rector Universidad de Almería; Antonia Contreras Ortega– Alcaldesa de Gérgal; Encarnación Zaguirre Fernández; Alcaldesa de Bacares; y Manuel Martínez Domene, Alcalde de Serón.

Using space and ground-based telescopes, including the 3.5 m at Calar Alto, an international team has discovered a rocky planet named Gliese 12 b. It is very similar in size to Venus and orbits in the habitable zone around the red dwarf star Gliese 12, less than 40 light-years from the Sun.
Thanks to its proximity and its equilibrium temperature of about 42°C, Gliese 12 b is an ideal candidate for studying its possible atmosphere with the James Webb Space Telescope when mini-eclipses (or transits) of Gliese 12 take place.

An impressive aurora borealis has been spotted in the Spanish skies on the night of May 10-11, 2024. From Calar Alto, despite the clouds, the intense reddish phenomenon has been captured by several webcams and even by the astronomers present there, who have been able to grab it with their cell phones. Other northen lights may well be seen on May 11th and 12th due to the power of the ongoing solar flares.
On May 9th, 2024, the American NOAA Space Weather Prediction Center's GOES-16 satellite observing the Sun detected strong coronal mass ejections from the giant sunspot called AR3664, the size of about 16 Earths. These ejections brought a solar wind that was directed right at our planet.
