An object that appeared in Earth's orbit, sparking curiosity about its origins since the 1950s. Initially thought to be a Soviet spy satellite, the Black Knight remains a mystery, and some believe it points to extraterrestrial life. Science has yet to explain its origins or characteristics.

Nikola Tesla detected unusual radio signals from it in 1899, but it did not receive significant attention until the launch of Sputnik 1 in 1957. The Black Knight is believed to orbit the Earth in the opposite direction of its rotation, raising suspicions about its nature. Media speculation grew in the 1960s as theories about its purpose spread.

Authorities dismissed it as space junk, while others suggested it may have military significance. The Black Knight's polar orbit has defied contemporary technology, leading to theories that it is an alien spy satellite.

Some believe it may be an ancient creation or an attempt at extraterrestrial communication, supported by mysterious signals decoded by researchers. Additionally, there are suggestions that ancient civilizations developed astronomical knowledge, which may be related to the Black Knight's existence.

Theories about lost civilizations such as Atlantis and evidence of underwater ruins add to the ongoing mysteries surrounding humanity's understanding of space and potential alien influence. The government's ongoing interest in unidentified aerial phenomena suggests a continuing search for the truth regarding extraterrestrial life and advanced technology.
