The first test images from its two instruments show its potential for achieving its scientific goals. These images will be used to check the instruments and to see how Euclid can be adjusted and fine tuned for best performance. The European Space Agency (ESA)’s Euclid mission, in which the Instituto de Astrofísica de Canarias (IAC) is participating, will produce the biggest and most accurate 3D map of the universe. Euclid’s two instruments VIS (VISible instrument) and NISP (Near Infrared Spectrometer and Photometer) have taken their first test images. The results indicated that this space

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 spectra
