Astronomers Find Primordial Stellar Stream in Milky Way’s Halo astronomy space science
— a search for the lowest-metallicity stars in and around the Milky Way using the Canada-France-Hawaii Telescope in Hawai’i — as being interesting enough to merit follow-up observations.
“It was not known if globular clusters with so few heavy elements exist — some theories even hypothesized they couldn’t form at all,” said Dr. Nicolas Martin, an astronomer at the Strasbourg Astronomical Observatory. The observations suggest that the ancient globular cluster must have formed from very early generations of stars, making C-19 a remarkable relic from the time when the very first groups of stars were being formed.
