The barred spiral galaxy that contains the Solar System, the Sun, and all stars visible to the naked eye.
Stars fall into broad populations: metal-rich Population I stars in the disc, like the Sun; old, metal-poor Population II stars in the halo and globular clusters; and a hypothesised first generation of metal-free Population III stars, not yet directly observed. Star clusters — young open clusters and ancient globulars — are coeval populations that serve as the great testing grounds of stellar-evolution theory.
A loose, irregular group of a few dozen to a few thousand stars born together from the same molecular cloud, found in the disk of the Galaxy. Their stars share an age and composition, making open clusters key laboratories for stellar evolution; because they are only weakly bound, they gradually disperse over hundreds of millions of years.
A cloud of interstellar dust that shines not by its own emission but by scattering the light of nearby stars. Because fine dust scatters blue light most efficiently, reflection nebulae typically appear blue — as in the wisps of nebulosity draped around the Pleiades.
