New research into a galaxy just 440 million years after the Big Bang using the James Webb Space Telescope suggest that supermassive stars cause globular clusters. … [+] in a sphere, with a radius from a dozen to a hundred light years. getty It’s almost globular cluster season.
One of the mysteries of our galaxy and every other, these dense groupings of up to a million stars—the most massive and oldest star clusters in the Universe—are a beautiful sight in a small telescope
As seen from the Orion spiral arm where we are these ancient relics appear clustered around the center of our galaxy, which in summer becomes visible to those of us in the northern hemisphere. But whether you get eyes-on with the Great Globular in Hercules, the Sagittarius Star Cluster, Omega Centauri or any of the other 177 visible around the halo of our Milky Way, known that some elusive questions about globular clusters remain unanswered by astronomers.
