How old is the oldest galaxy we’ve discovered?
EGSzs81. The galaxy EGSzs81 was discovered several months before the (now more distant and older) galaxy EGSY8p7, making it the oldest observable galaxy in the universe at the time. The galaxy is 13.13 billion years old and was formed 670 million years after the Big Bang.
How old is the youngest galaxy?
GNz11 is the youngest and most distant galaxy that scientists have observed. This video zoomed in on their location to a distance of approximately 32 billion light-years. GNz11 is 13.4 billion years old and formed 400 million years after the Big Bang. Its irregular shape is typical of galaxies of the time. 17

Is our galaxy the oldest of galaxies?
Our universe is about 13.8 billion years old, so most galaxies formed when the universe was still very young. Astronomers believe that our galaxy, the Milky Way, is about 13.6 billion years old. The youngest galaxy we know of formed only about 500 million years ago.
Are there galaxies older than the Milky Way?
Image by Federico Lelli et al./UBC. Astronomers have discovered a very surprising galaxy in the early universe that appears more mature than it should be for its age. They announced this result on February 11, 2021, noting that the ALESS 073.1 galaxy is about 12 billion light-years away.
Is the Milky Way the youngest of the galaxies?
Scientists used NASA’s Hubble Space Telescope to measure the age of possibly the youngest galaxy ever observed in the universe. Our galaxy, the Milky Way, on the other hand, is more than 20 times older, which is about 12 billion years old, which is the typical age of galaxies in the universe. …
