A neighbor both near and far

What’s that smudge up in the sky? Say hello to our closest neighbor — only 2.9 million light years away! The Andromeda Galaxy, M31, is at the same time the nearest major galaxy to our neck of the woods, and the most distant object readily visible to the naked eye. M31 is often considered a replica of our own galaxy, the “Milky Way.”
