Astronomers are Hunting Down the Elusive Population III Stars

It’s hard hunting down the oldest stars in the universe. These behemoths, known as Population (or Pop) III stars, are a missing link in cosmology between the primordial soup that was the early universe and the complex, “metal”-rich cosmos we’re familiar with today. But we’re slowly getting a better idea of where to look for them, and a new paper available in pre-print on arXiv from Alessandra Venditti of the University of Texas at Austin and her co-authors, highlights some of the recent advances and potential new surveying techniques that could eventually help us definitively find these massive, bright, early sparks in the universe.
