Supermassive star clusters like Westerlund 1 are groupings of stars that contain masses equivalent to tens of thousands of suns.
At over 6.6 light-years wide, the massive young stellar cluster in the Milky Way has a mass the same as around 63,000 suns. The James Webb Space Telescope also offers detailed and deep observations taken in infrared wavelengths of light that can be used to highlight young stars still surrounded by planet-birthing protoplanetary disks.
MIRI images reveal peculiar outflows and shells around the most evolved massive stars in Westerlund 1.
Young clusters with a moderate population of massive stars create large cavities in their clouds over the course of less than one million years .
Giuseppe: "In the next two to three years , we will publish most of the EWOCS science".
