The Maisie Galaxy was discovered last summer by a team led by astronomer Stephen Finkelstein.
Astronomers using modern instruments have learned a more accurate age for the Maisie Galaxy discovered by the James Webb Space Telescope (JWST) in June 2022. This is reported by Engadget.
Although not as old as originally thought, the star system is still one of the oldest on record, having formed 390 million years after the Big Bang, making it about 13.4 billion years old. It is only 70 million years younger than JADES-GS-z13-0, the oldest system known to date.
Initially, the team estimated that it did not appear until 290 million years after the Big Bang, but analysis of the galaxy with more advanced equipment showed that it is about 100 million years older than this figure.
Astronomers also examined the CEERS-93316 galaxy, which was originally estimated to be 235 million years old. However, after studying this system, it was discovered that it appeared a billion years after the Big Bang.
It was previously reported that the James Webb Space Telescope spotted a space object in the shape of a question mark.
