Webb and Hubble’s views of Westerlund 2
These images showcase the star cluster known as Westerlund 2, which resides in a stellar breeding ground known as Gum 29, located 20,000 light-years away from Earth in the constellation Carina. The cluster measures between 6 light-years and 13 light-years across, and is host to some of our Milky Way galaxy's hottest, brightest, and most massive stars.
This image on the left uses data from Webb’s Near-InfraRed Camera (NIRCam) and Mid-InfraRed Instrument (MIRI). The image on the right showcases a portion of the Hubble image of this same region, which was featured as Hubble’s 25th anniversary image in 2015.
