The birth of stars
NASA, ESA, the Hubble Heritage Team (STScI/AURA), A. Nota (ESA/STScI), and the Westerlund 2 Science Team
The sparkling centerpiece of this colorful Hubble image is a giant cluster of about 3,000 stars called Westerlund 2. The star cluster is only about 2 million years old and contains some of our Milky Way galaxy's hottest, brightest, and most massive stars. Some newborn stars are still buried in dense pillars of gas and dust. The region could be the home of young solar systems.
