The project, developed by the IAA-CSIC Sky Quality Office and with the support of the Granada City Council, will analyze how current environmental conditions have affected light pollution levels. Light pollution, produced mainly by excessive night lighting or incorrect lighting, represents an energy waste and endangers human health and that of ecosystems

About a year ago, the Event Horizon Telescope (EHT) collaboration released the first image of a black hole. They have now looked in detail at the high-speed jet of material emerging from a supermassive black hole

The first unequivocal detection of a jet of material at very high speed emerging from a galaxy in collision with another has been obtained. The jet emerges from the galaxy's central supermassive black hole and is seen head-on, a precursor structure to the formation of a blazar

Data from the TESS space telescope show variability in a sample of planetary nebulae, compatible with the presence of a companion star. This binarity could explain the complex morphologies of these objects, which result from the death of low and intermediate mass stars

ALMA radiotelescope captured a star in its evolution towards a planetary nebula

The optical engineer Concepción Cárdenas Vázquez has been awarded the MERAC Prize for the Best Doctoral Thesis in New Technologies (Instrumental) by the European Astronomical Society (EAS). The thesis encompasses the development of PANIC, an infrared, wide-field camera that operates on the Calar Alto Observatory

Calar Alto Observatory, scientifically co-managed by the IAA-CSIC, starts its energy transition thanks to a ERDF (European Regional Development Fund)-supported project. Using biomass and solar energy will considerably reduce the ecological footprint of the observatory, as well as the costs associated to its energy needs

A study led by the IAA-CSIC has revealed the existence of two rotating gas discs in the vicinity of the galaxy's supermassive black hole, as well as a third component that points to turbulent movements. MEGARA, a 3D spectrograph operating at the Gran Telescopio Canarias (GTC), demonstrates its ability to study the motion of gas and stars in galaxies in unprecedented detail

The black hole, which forms a binary system with a sun-like star, experienced an ejection of matter that transported gas over huge distances. An extensive observation campaign made it possible to follow the evolution of the ejected material, which shows how the black hole feeds back into the interstellar medium

The IAA is leading an investigation that shows, for the first time experimentally, the features of the particles of a comet's nucleus. Comets are considered to be pristine bodies, barely modified since their formation at the origin of the Solar System, and hide the key to how particles began to aggregate to form larger bodies
