Astronomers have used advanced instruments to calculate a more accurate age of Maisie’s galaxy, discovered by the James Webb Space Telescope (JWST) in June 2022. Although the star system isn’t quite as old as initially estimated, it’s still one of the oldest recorded, from 390 million years after the Big Bang — making it about 13.4 billion years old. That’s a mere 70 million years younger than JADES-GS-z13-0, the (current) oldest-known system.
