Still Waters Posted July 23, 2019 #1 Share Posted July 23, 2019 Some of the twinkling stars that spangle Earth’s skies are relics from the earliest beginnings of the Milky Way galaxy, astronomers have discovered. Formed within a few billion years of the big bang, these stars populated the burgeoning stellar conglomerate that, over eons, would grow and sculpt itself into the spiral galaxy we live in today. “They are as old as the oldest stars in the universe,” says Carme Gallart of the Institute of Astrophysics of the Canary Islands, who reports the findings today in the journal Nature Astronomy. The work marks the first time astronomers have pinned precise ages onto these ancient stars, which are a whopping 10 to 13 billion years old. https://www.nationalgeographic.com/science/2019/07/oldest-known-stars-in-milky-way-galaxy-found-gaia/ 1 Link to comment Share on other sites More sharing options...
