I wish we could be closer to a formation with a lot of stars and systems in our neighborhood. Probably not possible for life to survive there, but it would be an amazing view.

Whoa, there was a giant Play button in the galactic bulge at 1:30 !!! This will revolutionize our understanding of galaxy formation.

6:05 A bulge fossil object... Funny because that's what my wife calls me...

“Bulge Fossil Fragment” has to be the least sexy name for any type of astronomical object! 😂

So, it turns out that our entire understanding of globular clusters, based on less-detailed data, is oversimplified and inaccurate, when seen from the position of much more, and more detailed data. That's a very good summary of many of our prior "understandings" about the entire universe, what with the increasingly massive flow of good data from multiple sources. Don't worry about it. We're heading in the right direction. It just might not be in our lifetimes that we'll see physics become "complete."

That *young* *Australian* *Astronomer* *girl* covered this a few days ago. The cluster is called *Tregularium* and is believed to be no less than *seven* different clusters having *merged* in the last several billion years 🌌

Anton's code for 'a huge difference' = 'a tiny difference' 😉
