At a distance of 2.5 million light-years away from Earth it is our nearest major galactic neighbor. I have also included an annotated version for reference to help highlight the different objects in the frame.
Packed with over one trillion stars, M31 is the largest galaxy in our Local Group. This wide view beautifully showcases its expansive spiral arms, dark lanes of space dust, and bright center. Right next to the main galaxy, you can also spot its two smaller satellite galaxies: the small, packed ball of stars called Messier 32 and the more elongated, fainter one called Messier 110.
Fun fact A Cosmic Collision Course: Andromeda is screaming toward the Milky Way at roughly 110 kilometers per second. In about 4.5 billion years, our two galaxies will collide and will likely merge to form a brand new, giant elliptical galaxy.
