The star cluster Westerlund 2
This image shows the sparkling centrepiece of Hubble's 25th anniversary tribute. Westerlund 2 is a giant cluster of about 3000 stars located 20 000 light-years away in the constellation Carina.
Hubble's near-infrared imaging camera pierces through the dusty veil enshrouding the stellar nursery, giving astronomers a clear view of the dense concentration of stars in the central cluster.
