The amount of displacement is a function of the object's relative velocity toward the observer. Mos... Read more
Magellanic Clouds
Magellanic Clouds , two dwarf galaxies located in the far southern sky and visible to the unaided eye; they are classified as irregular because they show no definite symmetry or nucleus. The larger of the two, known as the Large Magellanic Cloud (LMC), is located mostly in the constellation Dorado; ... Read more

Milky Way
Milky Way the galaxy of which the sun and solar system are a part, seen as a broad band of light arching across the night sky from horizon to horizon; if not blocked by the horizon, it would be seen as a circle around the entire sky.
