A star cluster in the Milky Way appears to be as old as the universe

Star cluster M92, located 27,000 light-years from Earth, has been determined to be approximately 13.8 billion years old. The refined age estimate aligns closely with the age of the universe itself and helps establish the lower bound of the universe's age. By studying the ages of clusters like M92, astronomers can address discrepancies in measurements of the universe's expansion rate.
