A disk galaxy, also called a spiral galaxy, is shaped like a fried egg, said Cameron Hummels, theoretical astrophysicist at Caltech. These galaxies have a more spherical center, like the yolk, surrounded by a disk of gas and stars \u2014 the egg white. The Milky Way and our nearest galaxy neighbor Andromeda fall into this category.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Look into the night sky and you\u2019ll glimpse the stars from hundreds of billions of galaxies.
