SH2-308 - Dolphin-Head Nebula
5,000 light-years away, toward the constellation Canis Major, lies a huge bubble in space. This bubble formed when the massive star, EZ Canis Majoris, ejected its Hydrogen layer.
The fast-moving stellar winds (1,700 km/s) from the massive star shaped the bubble as they sweep up slower moving material from an earlier phase of the star's evolution. The nebula covers slightly more of the sky than the Full Moon. At its distance from earth this corresponds to about 60 light years in diameter.
EZ Canis Majoris is known as a Wolf-Rayet star. Twenty times more massive than our sun, Wolf-Rayet stars are thought to be in a brief phase of massive star evolution prior to becoming a supernova.
