Reply to comment by Cutthechitchata-hole in Enjoy the details. I work 16 hours edit and merge 380 RAW images of the moon and the final result was worth it by daryavaseum

If I remember right, elements heavier than iron can't be created in the normal fusion process that happens at the center of stars. Titanium is heavier than Iron. Titanium is created in supernovas, which do have the ability to form elements heavier than iron. So, maybe that's what you were thinking of?

Edit: I misremembered that. Iron is the heaviest element a star can fuse, but Titanium is lighter than Iron so it can be fused in stars. If I figure out why I was thinking Titanium was a supernova only element, I'll report back.

Titanium is not heavier than iron though?

Hmm. Yeah, you're right. I swear I heard Titanium as an example in some Science Channel documentary one time, but it must have been a different element.

We're not talking star creation or planet creation....

Plenty of asteroids are loaded full of metals and non metals, that's why they burn in different colors when they hit our atmosphere. For example, meteors made from primarily calcium will give off a purple or violet color, while those made out of magnesium will appear to have a green or teal color.

That's why some spots on the moon will appear different colors and in different shades due to age and composition of what hit it.

Well, yeah, but given that when the universe first formed there were no structures like atoms, all atoms that exist today had to have formed somehow. Titanium can't form in star fusion because it's too heavy, so all titanium that exists today had to have formed in some other process, like a supernova. Some Titanium likely "lived" through multiple supernovae to get to where it is today, in asteroids or on the Moon, etc.
