Wolf-Rayet Nebula is a nebula which surrounds a Wolf-Rayet star. There are different types of WR-nebula, based on their formation mechanism: 1.HII regions 2.ejecta-type nebulae 3.wind-blown bubbles 4.neutral hydrogen voids and shells (may be associated gas). The nebula shown is a 'wind-blown bubbles' type.
