Astronomers say they have found a cluster of galaxies 12.72 billion light-years away from Earth, which they claim is the most distant ever discovered.

Using a powerful telescope based in Hawaii, the Japanese team peered back through time to a point just one billion years after the Big Bang, the birth of the universe.

"This shows a galaxy cluster already existed in the early stages of the universe when it was still less than one billion years into its history of 13.7 billion years," the team of astronomers said.

The discovery was jointly made by researchers from the state-run Graduate University of Advanced Studies and the National Astronomical Observatory of Japan using the Subaru Telescope in Hawaii.
