The Calar Alto observatory will be integrated into RedIRIS-NOVA, the Spanish RedIRIS network of high-capacity dark fibre. This EU investment with MRR funds, worth about €2 million, will allow a better accessibility to the various datasets generated each night of observation by the multiple instruments of its telescopes, as well as open the possibility to access future research projects that require high bandwidth.
Calar Alto, like all large contemporaneous astronomical observatories, is located on top of a mountain, in the Sierra de los Filabres at 2168 meters above sea level. The site was chosen more than half a century ago, thanks to the quality of its sky, by German scientists who were searching the best place to observe stars and distant galaxies from the Old Continent.

Using data from the Calar Alto CARMENES and VLT (ESO Chile) ESPRESSO spectrographs, an international team of astronomers has discovered two Earth-mass planets orbiting the GJ 1002 star, a red dwarf about 16 light-years away from the Sun. Both planets lie in the habitable zone of GJ 1002, like the two exoearths of another nearby red dwarf, Teegarden’s star, found by CARMENES in 2019.
“Nature seems determined to prove that Earth-like exoplanets are very common. With these two, we already know seven of them in nearby systems”, explains Alejandro Suárez Mascareño, researcher at the Instituto de Astrofísica de Canarias and lead author of the article, accepted for publication in the Astronomy & Astrophysics journal.

Calar Alto has participated in the follow-up observations of a stellar explosion which lasted more than a minute and which cannot be explained with the current theoretical models of such bursts.
Gamma-ray bursts (GRBs) are the most energetic phenomena in the Universe, detectable even if they occur in galaxies millions of light-years away. They are classified as short or long GRBs, whether they last less or more than two seconds. Their duration is associated with their origin: long outbursts happen when very massive stars die, while short outbursts are related to the merger of two compact objects, such as neutron stars, black holes, or both.

TARSIS will be the next instrument to be installed on the 3.5-meter telescope at Calar Alto observatory. It is an integral field spectrograph with unique characteristics, capable of observing very wide fields in the near ultraviolet. TARSIS will make it possible to complete CATARSIS, a large survey of galaxy clusters, keeping Calar Alto at the forefront of astrophysical research.
On October 27-28th, 2022, the TARSIS kick-off meeting will take place at the University of Almería, marking the start of the development of the TARSIS instrument for the 3.5-meter telescope at Calar Alto observatory. This project is co-led by the Institute of Astrophysics of Andalusia (IAA-CSIC) and the Universidad Complutense de Madrid (UCM), in close collaboration with the Calar Alto Observatory (Hispanic Astronomical Center in Andalusia, CAHA), three Andalusian universities (Almería, Granada and Seville), the Astrobiology Center (CAB, CSIC-INTA), the industrial partner FRACTAL S.L.N.E. and the Mexican INAOE.
