Astronomers Determine Maisie’s Galaxy is Among the Most Ancient Ever Observed
Using sophisticated tools, astronomers have determined a more precise age for Maisie’s galaxy, which was first spotted by the James Webb Space Telescope (JWST) in June 2022. While the galaxy is not as ancient as initially thought, it remains one of the earliest observed, originating approximately 390 million years after the Big Bang, making it roughly 13.4 billion years old. This makes it only slightly younger, by a mere 70 million years, than JADES-GS-z13-0, the currently recognized oldest-known star system. The system was discovered last summer by Steven Finkelstein, an…
