On July 4, 1054, Chinese astronomers recorded a “guest star” in the Taurus constellation.
Later research uncovered contemporaneous sightings in Japan and the Middle East.
Temporarily outshining Venus, it faded after about two years: a common supernova.
Hundreds of years later, its remnant was astronomically discovered.
Halley’s comet was due to return that year, also in Taurus.
