Galaxy - Wikipedia - Galaxies were initially discovered telescopically and were known as spiral 18th to 19th century astronomers considered them as either unresolved star clusters or anagalactic nebulae, and were just thought of as a part of the Milky Way, but their true composition and natures remained a tions using larger telescopes of a few nearby bright galaxies, like the Andromeda ...

How to Choose Your First Telescope - Sky & Telescope - For example, from a dark location you can spot dozens of galaxies beyond our own Milky Way through a scope with an aperture of 80 mm (3.1 inches). But you'd probably need a 6- or 8-inch telescope (like the one shown at right) to see those same galaxies from a typical suburban backyard. And regardless of how bright or dark your skies are, the view through a telescope with plenty of aperture is ...

Doppler Effect in Light: Redshift and Blueshift - More generally, astronomers use redshift and blueshift to study objects that are moving, such as binary stars orbiting each other, the rotation of galaxies, the movement of galaxies in clusters, and even the movement of stars within our galaxy. Thus, by mapping the motions of these bodies, astronomers have managed to span an unusual amount of the “known universe”.
