A study reveals that light from these galaxies traveled for 13.4 billion years.
A study by an international team of astronomers has identified a group of the earliest galaxies confirmed to date. The team based its findings on the data processed by NASA’s James Webb Space Telescope (JWST). The galaxies are estimated to be less than 400 million years after the big bang, and light from these sources has taken roughly 13.4 billion years to reach the Earth’s atmosphere.

Astronomer and co-author, Emma Curtis-Lake from the University of Hertfordshire in the United Kingdom said that “it was crucial to prove that these galaxies do, indeed, inhabit the early universe. It’s very possible for closer galaxies to masquerade as very distant galaxies.”
