Scientists find leftovers from the universe’s very first stars

Astronomers have found the “fingerprints” of the explosions of the universe’s first stars.

The findings could give researchers a better view of what happened when the first stars formed after the Big Bang.

“For the first time ever, we were able to identify the chemical traces of the explosions of the first stars in very distant gas clouds,” said Andrea Saccardi, who led the study.

The findings are described in a new study, ‘Evidence of first stars-enriched gas in high-redshift absorbers’, published in the Astrophysical Journal.
