Today in history: July 4

A supernova appears above the Earth; a person standing in North America points up and says 'Cool!' A person in northern Africa looks towards it and says, 'Fascinating...' A person in eastern Asia looks towards it and writes notes while saying, 'Neat!'

July 4 1054: A supernova bright enough to be seen in daylight is witnessed by Chinese, Arab, and Amerindian observers.
