This is the first really good demonstration that the theory works on something like a star cluster.

This is the first really good demonstration that the theory works on something like a star cluster.

Both the brightness and the spectrum of the X-rays are very different from what theory predicts.

We believe this process of forming stars in a cluster was exactly the same thing that happened with our very own sun 4 1/2 billion years ago. It tells us a lot about the history of our own solar system.

If you look at the very young stars in the cluster and the spacing between them, it isn't random spacing. They're all about the same distance apart.
