Faintest early-universe galaxy found

                Scientists have detected the faintest early-universe galaxy yet, located about 13 billion light years away from earth. This new object could help astronomers understand the “reionisation epoch” when the first stars became visible. Gravitational lensing and a special instrument on the 10-metre telescope at the W M Keck Observatory in Hawaii, enabled the team to see the incredibly faint object. It would not have been visible if the light from the galaxy was not magnified by the gravitational lens, said Kuang-Han Huang, a researcher at University of California, Davis.
