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…

ALHAMBRA-gold data made public: the definitive catalogue to study the evolution of the universe

teaserThe first data sample from the cosmological project ALHAMBRA Survey has just been made public. This is the best available catalogue for the study of the evolution of the cosmos. This first data release, whose publication has been leaded by researchers from the Astrophysical Institute of Andalusia (IAA-CSIC), has been called ALHAMBRA-gold and it contains one hundred thousand galaxies, twenty thousand stars and one thousand possible active galaxy nuclei. The catalogue, developed at Calar Alto Observatory through observations performed with its Zeiss 3.5 m telescope, involves researchers from many other scientific institutions in Spain...

An extrasolar planet smaller than Mercury

teaserScientists belonging to the Center for Astrobiology (CAB/CSIC-INTA) and to Calar Alto Observatory, have taken part in the finding of the smallest exoplanet known to date. The object, smaller tan Mercury, was detected with Kepler space telescope and Calar Alto contributed with crucial data to confirm the finding. The results from this research are published in the February 20th 2013 issue of the international scientific journal Nature

The CALIFA survey unveils the evolution of galaxies in space and time

teaser small

The CALIFA survey, devoted to the study of galaxies in the near universe, has deduced for the first time the complete history of stellar formation for each one of the different regions of a set of one hundred galaxies. The researchers of this project, whose observations are performed at Calar Alto, have found that massive galaxies grew faster than lighter ones and, also, their inner central regions developed much earlier…
