The Wedderburn meteorite contains edscottite, which occurs in iron smelting. But it has never occurred in nature until now, when researchers sliced the meteorite open and found it hidden there.
Edscottite is one of the phrases iron goes through when it's cooling down from a high temperature, as it's smelted into steel. But the edscottite discovered in a tiny meteorite and officially named this year is the first to occur in nature. The Wedderburn meteorite's been sitting in Museums Victoria in Australia since it was found nearby in 1951, and researchers have sliced it open to search its contents just as long.

Just how it formed is still unclear. Geoffrey Bonning, a planetary scientist at the Australian National University who was not involved with the study, speculated to The Age that it was blasted out of the core of another planet.
