Common chemical elements are created in stars like our sun. But heavy elements, like iron, are thought to form in massive stars that explode and spew material — though it might be more complicated.

Traces of rare forms of iron and plutonium have been found at the bottom of the Pacific Ocean, after some kind of cataclysm in outer space created this radioactive stuff and sent it raining down on ...

Something went boom in outer space and sent radioactive stardust our way, and it's just been found at the bottom of the ocean. Traces of rare forms of iron and plutonium have been found at the bottom ...
