NASA's James Webb Space Telescope broke the record for the oldest galaxy ever observed.

Report: Nasa JWST

The James Webb Space Telescope spotted GLASS-z13, a galaxy that dates back to 300 million years after the Big Bang.

The James Webb Space Telescope, NASA's new infrared heavyweight, peered into the vast expanse and found a 13.5 billion-year-old galaxy, which researchers believe is the oldest galaxy ever detected.

When GN-Z1 was spotted by the Hubble Space Telescope in 2016, the galaxy's light had taken 13.4 billion years to reach Hubble.

Researchers told the two galaxies are also relatively small compared to our own Milky Way galaxy, which is 100,000 light-years in diameter.

GLASS-z13 is approximately 1,600 light-years wide, and The GLASS z-11 is approximately 2,300 light-years wide.

"With the advent of JWST, we now have an unprecedented view of the universe thanks to the extremely sensitive NIRCam instrument," researchers explained.

NASA says Webb is able to peer further and discover galaxies as far back as the first few hundred million years after the Big Bang.
