The James Webb Space Telescope has shown that supermassive stars may lurk at the heart of globular clusters born shortly after the Big Bang.

Geneva, Switzerland (SPX) May 12, 2023 - Globular clusters are the most massive and oldest star clusters in the Universe. They can contain up to 1 million of them. The chemical composition of these stars, born at the same time, shows anoma

The farthest galaxy in the universe A team of astronomers used the Keck I telescope to measure the distance to an ancient galaxy. They deduced the target galaxy GN-z11 is not only the oldest galaxy but also the most distant. Its so distant it defines the very boundary of the observable universe itself. The team hopes this study can shed light on a period of cosmological history when the universe was only a few hundred million years old. Weve all asked ourselves the big questions at times: "How ...

The farthest galaxy in the universe: Chemical signatures give away the distance A team of astronomers used the Keck I telescope to measure the distance to an ancient galaxy. They deduced the target galaxy GN-z11 is not only the oldest galaxy but also the most distant. It’s so distant it defines the very boundary of the observable universe itself. The team hopes this study can shed light on a period of cosmological history when the universe was only a few hundred million years old. We’ve all...
