Astronomers from the Australian National University think they've found one of the earliest stars to have formed in the Universe. It's called HE 1327-2326, and it has the lowest levels of iron ever found in any star. Heavier elements like iron only form inside stars, so HE 1327-2326 could have formed before successive generations of stars had seeded the Universe. This star was observed using the Japanese Subaru 8-m telescope, and found to be twice as iron poor as the previous record holder.
