Here, we present some of the best astrophotos of galaxies we have received from readers over the past few years.
It's incredible to think how relatively little we know about our own Milky Way, then to consider that each of the galaxies below is another system full of suns and planets: many rocky like Earth.
There could be two trillion galaxies in the Universe, and while all are currently out of physical reach, that doesn't stop astrophotographers from creating incredible images for the rest of us to marvel at.
Whether you're an astrophotographer or simply like snapping pics of the Moon with your smartphone, be sure to share your astro images with us.
