As part of the COCCON-España network of the Spanish State Weather Agency (AEMET), Calar Alto has participated in an intensive campaign to measure greenhouse gases. Along with a daytime atmospheric spectrometer at the observatory and another one installed at the University of Almería, the CARMENES instrument on the 3.5 m telescope has been used to quantify those gases during the night and feed the Astroclimes algorithm. This is a grounbreaking study of the global warming and its implications for climate change, in collaboration with AEMET and the universities of Almería (Spain) and Warwick (UK).

In the framework of the CAVITY project, an international team of researchers have studied in detail a remarkable couple of dwarf galaxies “dancing with each other” inside an unpopulated area of the Universe. This uncommon pair of low-mass galaxies merging “in the middle of nowhere”, near the center of a cosmic void, offers a unique view of one-on-one interactions and of the evolution of galaxies located in very low density environments.
