Reply to comment by -SmackMyBitchUp- 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
Wait...I thought I read that titanium is man made or not naturally occurring in nature. Is that not true? EDIT- so I either am thinking of another metal or maybe an alloy of titanium and something else. It seems like in the 90s there was suddenly an onslaught of new titanium products like eyeglass and sunglass frames as well as rings and I understood the metal to have been created. Maybe I'm misremembering or forgetting which metal I'm talking about. My bad y'all.

Titanium is a chemical element. Out of chemical elements, all of them from americium onwards are solely synthetically created in labs and such, while technetium and all elements from polonium onwards are rare naturally and radioactive (except for thorium and uranium, which aren't that rare.)
Titanium doesn't belong to either category.

You might be thinking of technetium. Titanium is actually pretty common.

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.

Naturally occurring pure, metallic titanium (native titanium) is so rare on earth that i don’t think it was discovered until the last century or something. AFAIK it’s only in little chunks that are smaller than a millimeter and only in a few rare places. Maybe that’s the source of the confusion?
