If all of the other pictures in this website are of objects in our own Milky Way Galaxy, this page shows other galaxies, each of which has its own diffuse nebulae, planetary nebulae, star clusters, and solar systems. Each of these galaxies is millions, tens of millions, or even hundreds of millions of light years away. Most galaxies contain hundreds of millions, or even hundreds of billions, of stars! They are hundreds of thousands of light years in diameter. Galaxies are seen to have many shapes. A spiral galaxy have arms that coil around the core of the galaxy. Elliptical galaxies appear to be tight balls. Irregular galaxies have ill-defined shapes. Galaxies can even be seen interacting or colliding with one another. Galaxies are usually gravitationally bound in groups. Our own Milky Way Galaxy is bound to the Andromeda Galaxy (M31), thePinwheel Galaxy (M33), Barnard's Galaxy (NGC 6822), and a host of other galaxies. These galaxy groups move through space together. Galaxies are often more challenge to image from light polluted locations. Still, they are fascinating and rewards subjects of inquiry.
