Spiral Galaxy

A face-on view of the Messier 74 galaxy shows billions of stars forming within its spiral arms. The clusters of blue are young stars, and the pink areas indicate concentrations of ionized hydrogen. Messier 74 is home to about a hundred billion stars, slightly fewer than the Milky Way has, and sits near the constellation Pisces some 32 million light-years away.
