According to historical accounts, the sky appeared filled with movement. Witnesses reported seeing hundreds of spherical objects, along with cylindrical craft from which smaller spheres seemed to emerge and dart rapidly through the air. 

A massive black triangular shape was also said to hover overhead, moving erratically. Some claimed that dark, spear-like ufos streaked across the sky, while smoke trailed behind falling spheres that appeared to descend toward the earth. 

So what really happened in the skies above Nuremberg more than four centuries ago? 

Modern ufologists have speculated that the objects described that morning may have been extraterrestrial craft engaged in combat. But the true nature of the 1561 Nuremberg event remains one of history’s most puzzling sky mysteries.
