Westerlund 2: Detail 2
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....
Westerlund 2: Detail 3
The pillars in the star-forming region surrounding Westerlund 2, composed of dense gas, are a few light-years tall and point to the central cluster. They are thought to be incubators for new stars. Besides sculpting the gaseous terrain, intense radiation from the most brilliant...
Westerlund 2: Detail 4
The red dots scattered throughout the landscape around Westerlund 2 are a rich population of newly forming stars still wrapped in their gas-and-dust cocoons. These tiny, faint stars are between 1 million and 2 million years old and have not yet ignited the hydrogen in their...

Flight to Star Cluster Westerlund 2 (Slower Flight)
