Calar Alto Observatory on the Night of the Researchers


Calar Alto Observatory took part on the European Night of the Researches with a roundtable and an exposition of anaglyph (3D images) showing the constellations, in collaboration with the Instituto Astrofísico de Andalucía (CSIC) and the Asociación de Amigos de Calar Alto.  




New Fireball Detection Station and related web page

bolido home

Since July 2014, Calar Alto Observatory has a fireball detection station which is composed by five high sensitivity CCD cameras. These devices are monitoring the firmament during the whole night and allow automatic identification of meteoroids entering into our atmosphere. These meteoroids are falling material fragments from asteroids, comets or even other planets. 

The systems installed at Calar Alto for the analysis of these interplanetary matter are part of the SMART project, developed under the scientific direction of Prof. José María Madiedo (Universidad de Huelva) in collaboration with the Instituto de Astrofísica de Andalucía (IAA-CSIC).

By clicking here you will go to the web page containing all the objects observed with this new system and with Calar Alto external surveillance webcams. That web page will be upgrade as soon as new fireballs are detected.



First planet confirmed from the Calar Alto Observatory




An exoplanet is confirmed for the first time using an instrument built by the Calar Alto Observatory. It is the first planet orbiting a giant star whose confirmation is beyond any doubt.

The planetary nature of an object orbiting the giant star KIC 8219268 has been confirmed by using the radial velocity technique and the Calar Alto Fiber-fed Echelle spectrograph (CAFE), the first instrument built by the Spanish-German Astronomical Center, in Almería, Spain. Researchers from the Center of Astrobiology (CAB, INTA-CSIC), the Max-Planck Institut für Astronomy (MPIA, MPG), Centro de Astrofisica e Departamento de Física e Astronomia (Universidade do Porto), Instituto de Astronomía (UNAM) and from Calar Alto (CAHA), in Spain, Germany, Portugal and Mexico have applied this well understood methodology and have obtained a mass similar to Jupiter. The planet, named Kepler-91b, is located extremely close to the star. This is the first planet ever confirmed based on data acquired from Calar Alto Observatory.



Calar Alto Observatory: at the forefront of galaxy sampling and the search for extrasolar planets


The dome of the 3.5-metre telescope at Calar Alto Observatory today hosted the launch of CALIFA and CARMENES, two international projects that are benchmarks in their respective fields.




Saturn’s hexagon from Calar Alto and from space

teaser lowResearchers from the Planetary Sciences Group of the Basque Country University (UPV/EHU) unveil some secrets of Saturn’s mysterious hexagonal wave, among them its rotational period, that may be the rotation period of the planet itself. The study, published in the scientific journal Geophysical Research Letters, has been based on data taken at Calar Alto Observatory and by the space probe Cassini



Ten billion years of cosmic evolution at hand

teaser en

On November 14th 2013 the complete data catalogue of ALHAMBRA project was made public: a survey of the cosmos devised to trace the evolution of the universe during the last ten billion years. Developed from Calar Alto Observatory, ALHAMBRA has identified, classified and computed the distance to more than half a million galaxies distributed over eight sky zones…
