M51 - The Whirlpool Galaxy

Mon Mar 27 2023

The Whirlpool Galaxy, Messier 51, is a classic face-on spiral caught in the act of interacting with a smaller companion galaxy tugging at the end of one arm. That gravitational dance is compressing gas and triggering waves of new star formation, making the Whirlpool one of the most photogenic galaxies in the sky.
