Beauties of The Universe: An Assortment of Favorite Galaxies

Click individual images for galaxy’s specific catalog name in case you find any you claim to be your favorite as well. Enjoy!

A massive, gravitationally bound system that consists of stars and stellar remnants, an interstellar medium of gas, dust, and an important but poorly understood component tentatively dubbed dark matter. The name is from the Greek word galaxias [γαλαξίας], literally meaning “milky”, a reference to the Milky Way galaxy. Typical galaxies range from dwarfs with as few as ten million (107) stars, up to giants with a hundred trillion (1014) stars, all orbiting the galaxy’s center of mass. -Wiki
