Important days in history of universe
July 4th was a significant day long before America started celebrating it. It also marks the first time on record that a new object appeared in the constellation Taurus -- an object so bright it could be seen in the daytime sky.
Not surprisingly, people around the world couldn't help but take notice. Chinese astronomers labeled it a "guest star" and noted that, at night, it shone almost four times brighter than Venus. They soon began speculating that its appearance heralded the Emperor at the time, Jen Tsung.
Meanwhile, on the other side of the globe, the Anasazi Indians of western North America may also have noticed the star. Archeologists believe images carved into Arizona rocks from that era depict the same mysterious phenomenon.
