The star cluster in the nebula NGC 3603 is located approximately 20,000 light years away from Earth in the Carina spiral arm of the Milky Way. Thousands of stars are located in this cluster. Most of the stars have masses that are similar to the mass of our sun. The Hubble Space Telescope has teken two images of the star cluster NGC 3603. The first image was from 1997 and the second image was from 2007. During those ten years, some of the stars in the cluster moved. However, they moved in such a way that was not expected by scientists. The video above shows a zoom into the star cluster. After the jump, you can see a video of the movements of some of the stars in the cluster.

The massive compact star cluster in NGC 3603 is shown in images taken ten years apart. The image is a colour composite of observations in the WFPC2 filters F547M (1997) respectively F555W (2007) (blue), F675W (green) and F814W (red). The field of view is about 35 arcseconds across. The boxes show a zoomed view of three foreground stars with a particularly high apparent speed relative to the cluster members. More fast-moving stars can be spotted by closer examination of the two pictures.
