The mission is part of the planetary defence strategy of the European Space Agency (ESA) The Instituto de Astrofísica de Canarias (IAC) is hosting this week the meeting of the Scientific Advisory Group (SAG) linked to ESA's NEOMIR (NearEarth Object Mission in the InfraRed) mission, which aims, among other things, to create a system for detecting near-Earth asteroids using a space telescope. The mission is part of the planetary defence strategy of the European Space Agency (ESA), which has set a possible launch date of 2030, using an Ariene 6-2 rocket.

An international study, carried out by the James Webb Space Telescope (JWST) in which the Instituto de Astrofísica de Canarias (IAC) has participated, shows that the universe could produce extremely luminous galaxies at very early epochs, when it was only some 3% of its present age. This result implies that these galaxies formed stars before, and more quickly than predicted by current theoretical models. The study also reveals an unusual galaxy that “imitates” the emission from a very distant galaxy. The results are published in the journal Nature. During the first months of scientificAdvertised on

H II regions are ionized nebulae associated with the formation of massive stars. They exhibit a wealth of emission lines in their spectra that form the basis for estimation of chemical composition. The amount of heavy chemical elements is essential to the understanding of important phenomena such as nucleosynthesis, star formation and chemical evolution of galaxies. For over 80 years, however, a discrepancy exists of a factor of around two between heavy-element abundances (the so-called metallicity) derived from the two main kinds of emission lines that can be measured in nebular spectraAdvertised on
