Stars and planets aren’t the only thing that populate the galaxy. Giant clouds of gas and dust, called “nebulae” (the Greek plural term for “clouds”) are also out there. These are places where stars are born, or sometimes are simply the remains of stars that have died. Some of the weirdest “dead stars” are actually neutron stars and black holes. Then, there are quasars, and weird “beasts” called magnetars, as well as colliding galaxies, and much more. Beyond our own galaxy (the Milky Way), lie an amazing collection of galaxies ranging from spirals like our own to lenticular-shaped ones, spherical, and even irregular galaxies.
