A super star cluster like no other ✨ Westerlund 1, 12 000 light-years away in the Ara constellation, is an extraordinary star cluster brimming with massive stars up to 2 000 times larger and a million times brighter than the Sun. Astronomers estimate that in less than 40 million years, over 1 500 supernovae will explode here! Captured in stunning detail by @esawebb, this image reveals the dense, star-packed core of Westerlund 1, providing key insights into star formation and evolution. It’s a unique window into some of the Universe’s most extreme environments! 📸 @NASA, @europeanspaceagency, @canadianspaceagency, M. Zamani (ESA/Webb), M. G.
