Introduction

Beyond the Sun, Moon and planets lie the stars of our Galaxy. Some are grouped together in clusters, others are spread out along the plane of the Galaxy along its spiral arms, a region rich in nebulae (vast clouds of gas and dust). Far beyond our Galaxy we encounter other galaxies, clusters of galaxies and quasars. These objects – galaxies, star clusters and nebulae – are what deep-sky observers study. (Historically, no distinction was made between what we today call nebulae, and galaxies – these “faint fuzzies” were lumped together as ‘nebulae’.) To find out more about these objects, visit the “Observing deep-sky objects” page.
