About this image

Westerlund 2 is surrounded by the star-forming region Gum 29. The heaviest cluster stars are unleashing a torrent of ultraviolet radiation and hurricane-force winds streaming with charged particles, etching away the enveloping hydrogen gas cloud from where the cluster formed. The nebula reveals a fantasy landscape of pillars, ridges, valleys, and reddish-brown filaments of dense gas and dust. The brightest stars in the image are Milky Way foreground stars not associated with Westerlund 2.
