Most metal-poor star hints at universe's first supernovae

A team of researchers, led by Miho N. Ishigaki, at the Kavli IPMU, The University of Tokyo, pointed out that the elemental abundance of the most iron-poor star can be explained by elements ejected from supernova explosions of the universe's first stars.

The presence of these massive stars has great implications on the theory of star formation in the absence of heavy elements.
