Have you ever wondered what the most distant object we can see with our naked eyes is?  The answer is The Triangulum Galaxy some three million light years from Earth.  This galaxy, along with the Great Andromeda Galaxy will collide with our Milky Way in about four billion years. This galaxy collision will herald in a new era for our home galaxy The Milky Way.  We will transform into an entirely new galaxy with billions more stars.   If you like this content, please consider supporting Deep Astronomy on Patreon!
