The Great Comet of 1066

The Great Comet of 1066 was a spectacular celestial event visible across Europe and Asia, notable for its bright, long tail and prominence in the night sky. It appeared shortly before the Norman Conquest of England, and its striking appearance was seen as an omen or significant sign by contemporaries. Comets like this are composed of ice, dust, and gas, producing glowing tails as they approach the Sun. Its visibility lasting several weeks made it remarkable and historically memorable, symbolizing change and upheaval during a pivotal period in medieval history.
