Flight to Star Cluster Westerlund 2

In honor of the telescope's anniversary on April 24, NASA released a virtual 3-D ride through space. The visualization takes you to a breeding ground for stars 20,000 light-years away from Earth. The little red dots in the video are new stars wrapped in gas-and-dust cocoons, NASA explained. Specifically, the flight goes through a cluster of stars called the Westerlund 2 that was discovered in the 1960s. It is located in the Gum 29 nebula in the Carina constellation, NASA said in a press release. The cluster is about 6 and 13 light-years across and is about 2 million years old. In space terms, those are baby stars, NASA said. NASA clarified that the video is a scientific representation meant to show what the cluster looks like in 3-D. "Note that the visualization is intended to be a scientifically reasonable interpretation and that distances within the model are significantly compressed," the video description reads.
