An awesome photo to say the least. The globular cluster imagery bar has just been raised.
On another subject, related to globulars, has anyone postulated or theorized why these clusters are more or less without macro structure?
Many galaxies have spiral/rotating structure (yes, I know there are some galaxies that look like giant globular clusters), yet the globs near us all seem to be these relatively uniform balls of stars.
Is the lack of overall rotational structure in globulars a result of how they formed? Their age? The fact that they're bound to a larger structure (e.g., the Milky Way)?
I've never been able to shake the feeling that globular clusters are somehow not made from the same "stuff" (e.g., from the big bang, if you believe in that theory) that makes up the rest of the universe.
