The Whirlpool Galaxy is a spiral galaxy that is relatively close to Earth — about 30 million light-years away. It is visible in the northern constellation Canes Venatici, just southeast of the Big Dipper
The Whirlpool’s most striking feature is its two curving arms, a hallmark of so-called grand-design spiral galaxies. Many spiral galaxies possess numerous, loosely shaped arms that make their spiral structure less pronounced. These arms serve an important purpose in spiral galaxies. They are star-formation factories, compressing hydrogen gas and creating clusters of new stars. In the Whirlpool, the assembly line begins with the dark clouds of gas on the inner edge, then moves to bright pink star-forming regions, and ends with the brilliant blue star clusters along the outer edge.
