A Hubble Heritage Release: April 23, 2015: NASA and ESA are celebrating the Hubble Space Telescope's silver anniversary of 25
years in space by unveiling some of nature's own fireworks — a giant cluster of
about 3,000 stars called Westerlund 2. The cluster resides inside a vibrant stellar
breeding ground known as Gum 29, located 20,000 light-years away in the
constellation Carina. The comparatively young, 2-million-year-old star cluster
contains some of our galaxy's hottest, brightest, and most massive stars. The
largest stars are unleashing a torrent of ultraviolet light and hurricane-force winds
that etch away the enveloping hydrogen gas cloud. This creates a fantasy
celestial landscape of pillars, ridges, and valleys...HubbleDite-NewsCenter
