The super star clusters hidden within these super nebulae...

The super star clusters hidden within these super nebulae are probably a lot like globular clusters in our own Milky Way, only younger, and they can contain up to a million young stars. The mystery is why our own Milky Way no longer forms globular star clusters and hasn't for 10 billion years. These galaxies still can. We want to know why. This is star formation on steroids.
