NASA Scientist Solves the 2,000-Year-Old Mystery of the Star of Bethlehem

A NASA scientist has proposed a new explanation for the 'Star of Bethlehem'—one that fits both biblical accounts and the laws of physics. Mark Matney’s research suggests a comet passed unusually close to Earth over 2,000 years ago, creating the illusion of a star standing still in the sky. Over 400 academic papers have examined the 'Star of Bethlehem', yet none have fully explained its described behaviour. Historical records from China’s Han Dynasty mention a 'broom star'—an ancient term for a comet—visible for more than 70 days starting in March 5 BCE. Matney’s calculations pinpoint June 8 of that year as the key moment.

A traveller moving from Jerusalem to Bethlehem would have seen the comet directly ahead. By around 10:00 AM, it would have appeared almost motionless overhead for nearly two hours. The comet’s close pass—just 390,000 kilometres from Earth—made this optical effect possible. Matney’s study, published in the *Journal of the British Astronomical Association*, marks the first time a comet has been identified as a plausible astronomical candidate for the phenomenon. Unlike previous theories, this explanation aligns with both scriptural tradition and scientific principles.

The findings offer a fresh perspective on an ancient mystery. The comet’s trajectory and timing match the biblical description of a star that seemed to pause in the sky. This research provides the first scientifically supported answer to a question debated for centuries.
