A team of researchers, including scientists from MIT and the Carnegie Institution of Science, has analyzed the chemical composition of stars in the fossil galaxy known as Segue 1. The dwarf galaxy, containing roughly 1,000 stars, sits 75,000 light years away from Earth, and is host to a set of unusual features that are allowing astronomers to observe the composition of stars from the early universe.
