Earthsky Tonight—May 06, Milky Way encircles the horizon on May evenings

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Where is the Milky Way these days? That faint luminous band of stars crossing the dome of sky is nowhere to be seen on May evenings. Why? The disk of our Milky Way is shaped like a pancake. On May evenings, the plane of the pancake-shaped galactic disk coincides with the plane of the horizon. Because the Milky Way disk sits along the horizon in every direction, the Milky Way doesn’t appear in the sky on May ... Full Story
