NASA'S James Webb Space Telescope has found the oldest galaxy ever seen in the universe.
According to scientists, the galaxy is called GLASS-z13 and it dates back to 300 million years after the Big Bang.
In comparison, the Earth is thought to be around 4.5 billion years old.
The Milky Way is the galaxy the Earth calls home and it's said to be around 13.6 billion years old.
Nasa's James Webb Space Telescope is on an unprecedented mission to let us explore the universe more than ever before.
It's aiming to find even older galaxies than GLASS-z13 and essentially look back in time to help us learn more about how the universe formed.

The previous record-holding ancient galaxy is called GN-Z11 but the newly observed galaxy beats this by around 100 million years.
The ancient GLASS-z13galaxy is said to have a mass bigger than one billion suns.
Despite this large mass, it's actually smaller in size than the Milky Way we call home.
The Milky Way is about 100,000 light-years wide, whereas the GLASS-z13 galaxy is only a few thousand light-years wide.
