Like a ship plowing through cosmic seas, Runaway Star Alpha Camelapartilus has produced this graceful arcing bow wave or bow shock. The massive Super Giant Star moves at over 60 km per second through space, compressing the interstellar material in its path. Alpha Cam is about 25-30 times as massive as the Sun, 5 times hotter, 30,000 Kelvin, and over 500,000 times brighter.
