CARMENES is a visible and infrared spectrograph that operates from the Calar Alto Observatory

CARMENES instrument, designed to search for extrasolar planets from the 3.5-meter telescope of the Calar Alto Observatory, has allowed to find two planets around the Teegarden´s star, one of the closest known. With masses similar to Earth's, their temperatures could be warm enough to support liquid water on the surface, according to the study published in the journal Astronomy & Astrophysics.

Located at a distance of only 12.5 light years, the Teegarden´s star is the star system number twenty-four closest to ours, and one of the smallest red dwarf stars known. Despite its proximity and due to its low brightness, the Teegarden´s star was not identified until 2003.

The regional government of Andalusy is getting involved in the co-management of the observatory, along with the Spanish National Research Council (CSIC)

La The Economy, Knowledge, Companies and University ministry of Junta de Andalucía and the German Max Planck Society (MPG) have already signed, before a notary public, the transfer of 50% of the shares (social parts) that MPG had in the Calar Alto astronomical observatory.

With this signature, the autonomous administration of Andalusy will share its exploitation with the Spanish National Research Council (CSIC), which depends on the Spanish Ministry of Science, Innovation and Universities.

After receiving for free the shares, the Andalusian department head by Rogelio Velasco will bring 1.5 million euros per year to maintain and develop the observatory activities.

On April 9th, 2019, the Governing Council of the regional government of Andalusia (Junta de Andalucía) authorized its Administration, through the Ministry of Economy, Knowledge, Companies and University, to enter the Economic Interest Group of the Calar Alto Observatory (CAHA) in Almería. This decision finishes the adhesion procedure and authorizes the consequent acquisition by the Junta of 50% of the A.I.E. company's shareholdings in substitution of the German Max-Planck-Gesellschaft  (MPG) which transfers them free of charge.

Junta de Andalucía is substituting the former MPG co-partner, along with the Spanish Superior Research Council (CSIC), guaranteeing the continuity of this first class scientific complex, whose science and technology strategy are co-managed by the CSIC through the Institute of Astrophysics of Andalusia located in Granada.

A nearby green pea galaxy, analog to the first galaxies, shows how the young Universe became illuminated

portadaMarch 25th 2019

A team of astronomers have used PMAS on the 3.5-m telescope to study a nearby star-forming galaxy, emitting energetic photons in a similar way to the first generation of galaxies

These first galaxies turned the Universe transparent, less than one billion years after the Big Bang

The young Universe was a dark place. A few hundred million years after the Big Bang, the first stars formed, and their ultraviolet radiation ionized the hydrogen atoms that populated the Universe and absorbed the radiation. This is called the Era of Reionization, and marks the time when the Universe became transparent to light (and, hence, observable). Now, a team of astronomers have used the PMAS instrument at Calar Alto Observatory to study a green pea, a local analog to the first galaxies, to better understand how ultraviolet light escapes and ionizes distant areas, in a process similar to that of Reionization.
