NGC 488

The Race is On: A near-perfect spiral galaxy lies 90 million light years away, its bluish arms containing rings of star formation. Stars within NGC 488 complete circular orbits at a speed of 205 miles per second (330 km/s), edging out the stars traveling at 137 miles per second (220 km/s) within our own Milky Way. Despite the high speeds, the concentric rings of star formation remain stable.
