Description

Gum 15, also known as RCW 32, is about 3,000 light-years away in the constellation of Vela. It is shaped by aggressive winds flowing from the stars within and around it. The bright star near the center of the nebula is HD 74804 which is responsible for ionising the gas. The central region shows dark patches of dust, while deeper pictures show some faint reflection structures crossing it that are only dimly visible in this picture. The various combinations of emission, reflection and dark nebulae make the nebula resemble a larger and fainter version of the better known Trifid Nebula.
