Astronomers believe that our own Milky Way galaxy is approximately 13.6 billion years old. The newest galaxy we know of formed only about 500 million years ago.
How old is the oldest galaxy in the universe?
The oldest known galaxy in existence remains GN-z11, which formed around 400 million years after the Big Bang, as previously reported by Live Sciences sister site Space.com.
How old is our galaxy compared to others?
Our universe is about 13.8 billion years old, so most galaxies formed when the universe was quite young! Astronomers believe that our own Milky Way galaxy is approximately 13.6 billion years old. The newest galaxy we know of formed only about 500 million years ago.
Are we the oldest galaxy?
GN-z11 is currently the oldest and most distant known galaxy in the observable universe, having a spectroscopic redshift of z = 11.09, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs) .GN-z11Apparent magnitude (V)25.8HCharacteristicsTypeIrregularMass~1×109 M ☉12 more rows
Is there a star older than the universe?
Since HD 140283 is a Population II star, it is older. In fact, it is the oldest star with a well-determined age. Because of this, astronomers colloquially call the star “the Methuselah star.” Initial estimates of its age were in excess of 14 billion years.
What is the youngest thing in the universe?
GN-z11 is the youngest and most distant galaxy scientists have observed. This video zooms to its location, some 32 billion light-years away. GN-z11 is 13.4 billion years old and formed 400 million years after the Big Bang. Its irregular shape is typical for galaxies of that time period.

What is the oldest universe?
Bond has led studies of the oldest-known Population II star – dubbed HD 140283, or the “Methuselah Star,” after an extremely long-lived patriarch in the Bible – which is about 200 light years from Earth and estimated to be more than 13.5 billion years old.
Which is the most beautiful galaxy?
The Andromeda galaxy is 2.537 million light-years away from Earth in the constellation Andromeda. Its closeness to our planet makes it the most distant object visible to the naked eye on Earth. It is the nearest giant galaxy and contains approximately the same number of stars as the Milky Way.
