History of Márcio Farias - Viseu, Portugal
Different sizes and shapes are found among galaxies: among them, spiral, elliptical and irregular. Spiral galaxies stand out for their luminous central core, from which several arms emanate. Irregular galaxies, on the other hand, do not adopt defined shapes and are composed of young stars rich in gases and dust particles. As for quasars, they represent intensely luminous cores of galaxies located at great distances. These structures were identified in the 1960s. Initially observed with optical telescopes, these objects resembled stars, giving rise to the name "quasars".
