Westerlund 2 - a star cluster named for Swedish astronomer Bengt Westerlund who discovered the grouping in the 1960s

The sparkling centerpiece of Hubble's anniversary fireworks is a giant cluster of about 3,000 stars called Westerlund 2, named for Swedish astronomer Bengt Westerlund who discovered the grouping in the 1960s. The cluster resides in a raucous stellar breeding ground known as Gum 29, located 20,000 light-years away from Earth in the constellation Carina.
