Westerlund 2


Westerlund 2, a giant cluster of about 3,000 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.


The 2-million-year-old giant star cluster measures about 6 to 13 light-years across and contains some of our galaxy's hottest, brightest, most massive stars.
