• We get light from almost every star in the universe, as long as the light has had time to REACH the earth since the star was formed. When you look in the night sky you see stars (and galaxies with a telescope) in every direction. Almost all the stars you can see with the naked eye reside within our own galaxy, the Milky Way. Some stars may be obscured by gas or dust clouds. Andromeda is the next-door neighbor galaxy. All galaxies besides our own appear -- without high magnification -- as only faint smudges among the stars. In fact, they were once thought to be mere clouds of gas before they were resolved as vast collections of individual stars. Now we realize that our Milky Way is one of hundreds of billions of galaxies distributed throughout the observable universe.
