In the ancient light of a distant galaxy, Canadian astronomers have found what may be the universe's oldest known stars—stellar fires that ignited a mere 500 million years after the Big Bang, preserved within dense globular clusters orbiting a galaxy they have named the Sparkler. Using the James Webb Space Telescope and the magnifying grace of an intervening galaxy cluster, a team from Toronto and the National Research Council peered further back into cosmic time than any instrument before them could manage. The discovery does not merely add a date to a catalog; it suggests that globular clust
