The Calar Alto Observatory opens up its doors to the public

firmaPortadaMarch 1st 2016

The Spanish-German Astronomical Centre at Calar Alto (CAHA, MPG / CSIC) and the company Azimuth-Education and scientific tourism, have signed an agreement for the management and development of astrotourism and outreach activities from the observatory and its environment

The Calar Alto Observatory, the largest astronomical complex in continental Europe, has signed an agreement with the company Azimuth to develop a program that will allow citizens to visit the observatory and access facilities and instruments that until now have only been available to professionals. Activities will begin this March and will be open for booking, either individually or in groups through the web or by emailing to:





PlanetCam UPV/EHU camera is fully operational at Calar Alto Observatory (CAHA)

The camera aims to study the Solar System objects, but it can also be used for the observation of any object with high gloss that requires a high spatial resolution.

Calar Alto Observatory has a new instrument, the PlanetCam camera that, developed by University of Basque Country (UPV/EHU), offers a big spatial and temporal resolution in both the visible and the infrared channels, and that will work at the 1.23 and 2.2 meters telescopes .




The European Space Agency (ESA) will search for potentially dangerous objects from Calar Alto

ESA and Calar Alto have signed a collaboration agreement for the exclusive remote use of the 80 cm. Schmidt Telescope.

NEOs (Near Earth Objects) are comets or asteroids which their orbits, possibly modified by gravitational pull of planets, lead them to regions near to the Earth orbit. Although possibilities of an impact against the Earth are very reduced, the scientific community are developing programs for detecting and studying such objects. Calar Alto Observatory (CAHA, MPG/CSIC) has signed an agreement with European Space Agency (ESA) for the exclusive use of one of its telescopes in ESA’s NEOs detection campaign.



First Successful Tests of New Planet Hunter “CARMENES”

17/12/2015. CARMENES, an outstanding novel astronomical instrument, which has been designed to look for Earth-like planets, has successfully passed first “on-sky” tests at the telescope. Scientist and engineers of Calar Alto Observatory have participated in the design and construction of the new “planet hunter”. After five years of preparation, the highly complex instrument was for the first time used in November at the 3.5m telescope of the Calar Alto Observatory near Almería in southern Spain, which is operated jointly by the Max-Planck-Society (MPG) and the Spanish National Research Council (CSIC). CARMENES has been designed and built by a large international consortium of eleven institutions in Germany and Spain. The instrument consists of two spectrographs to analyze the visible and the infrared light coming from celestial bodies. Both have been optimized for the discovery of planets orbiting nearby stars. Thus, observations with CARMENES will be an important milestone for one of the most exciting areas of space exploration - the search for a second Earth.



UPDATE: "Halloween pumpkin" video and images from Calar Alto

PortadaThis is an update from previous new. As told yesterday, an international group of researchers have observed the 2015TB145 NEO, also known as "The great Halloween pumpkin" with the 1.23m telescope and with PMAS instrument at 3.5m telescope. Here you have images and the video of the observations.

The image on the left shows the asteroid. If you click below on the "read more" button, you'll have access to a complete video.




A group of researchers will observe "The great Halloween pumpkin" from Calar Alto tonight


The nights of October 30th and 31st are the best opportunity for studying this asteroid, which characteristics points that it could be an extinct comet.

The asteroid, with 400 meters wide, will be at about 480.000 km from Earth at its closest approach.
