In the early 20th century, British Colonel Percy Harrison Fawcett found a mysterious document in the National Library of Brazil that spoke of an ancient city lost in the jungles of the Amazon. Then, during an expedition with his son and a companion in 1925, the three explorers vanished. However, it is believed that they might have been close to the place they were looking for.
When Fawcett found Manuscript 512, he was taken aback. The document was written by Portuguese bandeirante João da Silva Guimarães and stated that as early as 1753, explorers had discovered ruins that included arches, a statue, and a temple engraved with enigmatic hieroglyphs. And although the narration was detailed, the city's exact location was not mentioned.
Fawcett then began preparing an expedition to find the ruins, but World War 1 broke out, and the British government withdrew its support.
After serving in the Western front during the war, Fawcett undertook a personal journey to find “Z” in 1920, but was forced to stop due to an illness and the fact that he had to shoot his own pack animal.
The adventurer tried again five years later, this time accompanied by his son Jack and a friend of his, Raleigh Rimell. However, the three soon disappeared in the Mato Grosso jungle.
Several researchers argue that the explorer might have been influenced by indigenous tales, and locals could have told Fawcett of the archaeological site of Kuhikugu, near the Xingu River.
After Fawcett’s presumed death, the actual site of Kuhikugu was discovered, and it contained the ruins of about 20 towns and villages. Moreover, it is estimated that about 50,000 people might have lived in the extensive township.
In addition, vast geometrical earthworks were discovered in interfluvial settings along the southern Amazonia, and this fact has been recognized as supporting Fawcett’s theory.
While some relate the Lost City of Z with the infamous El Dorado, the mythical place has inspired its own set of stories, including a book by David Grann and a film adaptation by director James Gray.

![Sky Trumpets: 5 Frightening Unexplained Sounds from the Sky
Presenting the latest unexplained sky sound phenomena... On the evening of October 11, 2023, residents of New Hampshire, in the New England region of the United States, were alarmed by a deafening, booming explosive sound that rattled their windows and shook entire homes for a full 12 seconds. No initial cause could be identified.
Harvard Universitys astronomical equipment managed to record the sound, but analyses determined that the source of the sound could not have been birds, aircraft, or wind.
Speculation ran rampant on social media, fueled by firsthand accounts of the unsettling event. Residents theorized that the cause might be a sonic boom from an aircraft or, more fancifully, aliens testing technology in our atmosphere.
Avi Loeb, a former Harvard astronomer and physicist who has since turned his attention to the search for extraterrestrial intelligence, initiated a further investigation. Loeb had founded the Galileo Project at Harvard, installing an ultra-sensitive microphone on the roof of a campus building.
The Galileo Project is an international initiative dedicated to the search for extraterrestrial intelligence and technology, focusing on UFO and aerial phenomena. It employs optical and auditory equipment to systematically scan the skies.
As the community pondered the phenomenon, Loeb concluded that the source must have been an unidentified flying object, detonating with the force of 2,400 pounds of TNT. One of Loeb’s posts on the matter queried, Is this an Unidentified Anomalous Phenomenon? [...] Are aliens using advanced technologies near Earth?
The same roaring noise was detected in Massachusetts, where it was discovered to have been moving at 1,115 feet per second, based on the burst of pressure that swept across the Earths surface in the wake of the boom.
Combining the evidence, Loeb deduced that the UFO was likely a meteor, noting, The inferred energy and distance are reminiscent of meteors, which are known to make their own music at high altitudes.
Supporting Loeb’s meteor hypothesis, this phenomenon occurred during the Orionid Meteor Shower, an annual event each autumn that can produce up to 25 shooting stars per hour at its peak. The meteor is likely to have been a fragment from this shower.
Although the investigation concluded that alien technology was not involved, the size of the meteor—and the force of its explosion—remains a significant cause for concern, especially given that it was not detected approaching Earth.
Loeb remains a controversial figure within the scientific community. In 2023, he also claimed to have recovered material from an interstellar meteor containing evidence of alien technology. The potential for retrieving material from the meteor that alarmed New England remains uncertain.
It may be that other similar phenomena will support theories of alien intelligence, such as the mysterious flash and boom witnessed in Minnesota in the same month as the New England event. Despite being captured on camera, the plummeting object behind the Minnesota boom remains unexplained...
