UC researchers find evidence of cosmic cataclysm 1,500 years ago at 11 ancient sites.
The rapid decline of the Hopewell culture about 1,500 years ago might be explained by falling debris from a near-Earth comet that created a devastating explosion over North America, laying waste to forests and Native American villages alike.
Researchers with the University of Cincinnati found evidence of a cosmic airburst at 11 Hopewell archaeological sites in three states stretching across the Ohio River Valley. This was home to the Ohio Hopewell, part of a notable Native American culture found across what is now the eastern United States.
The comet's glancing pass rained debris down into the Earth's atmosphere, creating a fiery explosion. UC archaeologists used radiocarbon and typological dating to determine the age of the event.
The airburst affected an area bigger than New Jersey, setting fires across 9,200 square miles between the years A.D. 252 and 383. This coincides with a period when 69 near-Earth comets were observed and documented by Chinese astronomers and witnessed by Native Americans as told through their oral histories.
The study was published in the Nature journal Scientific Reports.

Many citizens living in the Marmara and Aegean regions shared the images of a meteor shining green light on social media.
The green light beam seen in the sky of Istanbul at night surprised those who saw it.
Images shared by citizens on social media sat on Turkey's agenda. It was a matter of curiosity what the object seen from many cities was. Some users claimed that a meteor fell in Istanbul.
A green light rapidly descending from the sky caught the eye in the images.
