Chemistry / Re: Where does Titanium come from?

Like all elements heavier than lithium, titanium is produced (with the exception of possible radioactive decay routes) in the cores of stars. Because of its large number of protons, high energies (temperatures) are needed to overcome the repulsive force between the fusing nuclei. Thus, titanium is produced predominantly in the cores of massive (significantly more massive than the sun) stars and in supernova explosions. Supernovae are the key mechanism for distributing titanium throughout the universe (including on/in earth).
