The ancient Greeks may have been the first to spot Halley's comet, researchers say. Ancient Greek writers wrote about a large object crashing into northern Greece between 466 and 467 BC. The writer also described the comet's shape in the sky and its descent to the Earth, but these details did not attract much attention.
