IAA-CSIC researchers participate in the discovery of one of the few known planetary systems in this type of stars.
The results, published today in Nature Astronomy, have been contributed by the Sierra Nevada and Calar Alto observatories.


The James Webb Space Telescope observes star clusters in a galaxy just 460 million years after the Big Bang.
The Instituto de Astrofísica de Andalucía (IAA-CSIC) and the Instituto de Física de Cantabria (IFCA-CSIC-UC)
are participating in this discovery.


Researchers from IAA-CSIC lead a new method to measure carbon dioxide snow and frost variations on Mars surface.
The initial results indicate that the deposited snow thickness is up to two orders of magnitude greater than estimated.


The Instituto de Astrofísica de Andalucía (IAA-CSIC) is co-leading the study of the second lightest planet
discovered to date, WASP-193b





The scientific activities of the Instituto de Astrofísica de Andalucía require the analysis, design, prototyping, manufacture and integration of astrophysical instrumentation. To carry out all these tasks the Instrumental and Technological Development Unit UDIT has a Mechanical department, Optics laboratories, Electronics and Software as well as two clean rooms of ISO 8 class.

Astronomical Observatories


The Sierra Nevada Observatory (OSN) is a high mountain observatory located in Loma de Dilar, in the ski resort of the Sierra Nevada mountain range (Granada). The OSN is operated, maintained and supplied by the Instituto de Astrofísica de Andalucía (IAA-CSIC). It consists of a main building which hosts two Nasmyth optical telescopes of 90-cm and 1.50-m diameter each, as well as a 60-cm IR semi-automated telescope and a 35-cm telescope.

The German-Spanish Astronomical Center at Calar Alto is located in the Sierra de Los Filabres (Andalucía, Southern Spain) north of Almeria. It is operated jointly by the Junta de Andalucía and the Instituto de Astrofísica de Andalucía (CSIC) in Granada/Spain. Calar Alto provides three telescopes with apertures of 1.23m, 2.2m and 3.5m to the general community. A 1.5m-telescope, also located on the mountain, is operated under the control of the Observatory of Madrid.

Take a taxi to the IAA or your hotel directly. There are some buses from the aiport to Granada, but they are not syncronous with the planes...

At the train station, ask for Av. de la Constitución and get on bus LAC to Palacio de Congresos. Get off Palacio de Congresos stop and change to bus S2, direction to Villa Argaz. This bus has a stop very close to the IAA, only a few meters.

At the bus station, get on bus SN2 to Palacio de Congresos. Get off at the bus stop Tierno Galván - Palacio de Congresos and change to bus S2 to Villa Argaz. The S2 route passes in front of the IAA. Get off at the first stop of Camino Bajo de Huétor Street, then walk for a few seconds and you'll be here.
