NOMAD instrument, aboard the ExoMars (ESA) mission in orbit around Mars, has detected this diurnal emission of atmospheric oxygen for the first time outside Earth. The green line provides information on the composition and dynamics of the atmosphere, and this detection has also allowed to resolve a controversy between atmospheric measurements on land and atomic calculations

The volume includes 77 short articles on current research topics about the Sun, written in a plain language by scientists from 30 European research institutions and universities.


The Institute of Astrophysics of Andalusia (IAA-CSIC) participates in the study of the expansion of the shell of material ejected by various nova explosions. They find that, contrary to what was assumed, novae expand unrestrained until their end, when they end up dissipating in the interstellar medium

Researchers from the Institute of Astrophysics of Andalusia detect, in data files from 2009, an elevated stratopause in November, a phenomenon never seen outside the winter period

The Institute of Astrophysics of Andalusia (IAA-CSIC) is involved in a project financed by the Carlos III Health Institute for the development of a prototype to analyze surfaces contaminated by SARS-CoV-2. The IAA will contribute with polarimetry studies to the project, which already combines image acquisition in the entire optical and sub-millimeter range and its analysis with artificial intelligence


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
