3. Stainless Steel's Snooze Button

They say rust never sleeps, but it just might be hitting the snooze button for stainless steel: Iron, when alloyed with at least 11% chromium, creates a passive film of chromium oxide that prevents the iron content from corroding, keeping it non-corrosive and robust for a lengthy lifespan.

12. Star Spectra Iron Fashion

In a galaxy far, far away, stars just couldn't resist accessorizing with a touch of fancy iron: Iron actually helps to determine the chemical properties of a star's atmosphere! By examining the gap-toothed smiles in a star's spectrum, astronomers can find out how much iron is present, and other crowd favorites like helium, magnesium, and silicon. These elemental proportions spill the tea on the star's age and the nitty-gritty of any planets orbiting it.
