A Signature of the Universe's First Stars? (1 of 2)

Caption

Massive and luminous first-generation stars in the universe would form a cluster. Among them, the most massive ones, which could be more than 100 times more massive than the sun, explode and eject material including heavy elements, in particular iron. This material relates to a paper that appeared in the Aug. 22, 2014, issue of Science, published by AAAS. The paper, by Wako Aoki at the National Astronomical Observatory of Japan (NAOJ) in Tokyo, Japan, and colleagues was titled, 'A chemical signature of first-generation very-massive stars.'
