Yeah. I think globular clusters are made up mainly of older stars.

Nor do I. What I said in the first post is all I know about them, really. I don't know how they're formed or anything.

Yes, you are right. Globular clusters are mostly older stars. They combine when they get close enough to each other, but never new stars are made in them.

I'm not sure about this, but I think they can form new planets over time.

Actually, I think I may have been wrong about the planet part, sorry.

But I know for a fact that they are old stars. They are located in the older part of our galaxy where there are no new stars.

Some of them do have black holes at the centre, though. I suppose in some ways, they're like mini-galaxies.

You may be thinking of neutron stars...

I believe they are made up of older stars. There are just too many that they can't escape each other's gravity.

I'm pretty sure they are.

It is. It almost looks like a nebula, actually, with that red background.
