Star Light, Star Bright, First Star I See Tonight…

Make that, “first star” ever.

Talk about glimmers from the past. Some of the universe’s first stars may still be shining in the Milky Way 13.4 billion years after they formed, new simulations suggest.

The study, reported online February 3 in Science and posted at arXiv.org on January 28, contradicts the prevailing view that the first stars were all behemoths that burned brightly and died out in a few million years.

In their simulations, Paul Clark of the University of Heidelberg in Germany and his colleagues showed that gas clouds in the early universe could have forged several stellar embryos rather than just one. …

The infant stars in each cloud were closely spaced, and the team suggests that their mutual gravity could kick the lowest-mass embryo from the tightly packed group — before that infant had a chance to grow into a massive, short-lived star.
