In the constellation, the brightest recorded supernova in human history erupted in the past. It was noticed by the inhabitants of China and Japan, as well as the Middle East and Europe. When it first appeared in the sky in the spring of 1006, it was about as bright as Mars in opposition. However, within a few weeks, it easily surpassed Venus and brightened to -7.5 magnitude, equivalent to the brightness of the Moon in the first quarter. The supernova remained visible for the next two years, and even briefly during the day. Today, we only observe a cloud of debris from the ancient stellar explosion at this location.
