As the curtain falls on 2025, several enigmatic events continue to baffle the world, leaving many unanswered questions.

This year has felt like a chapter straight out of a science fiction saga, with thousands of UFO sightings along the US East Coast, an unexpected celestial visitor entering our solar system, and the intriguing possibility of colossal structures being discovered beneath the Egyptian pyramids.

In addition, both scientists and officials are still grappling with wild theories surrounding these astonishing occurrences. Among these is a noteworthy scientist’s assertion that the massive space object known as 3I/ATLAS might actually be a spacecraft from another world.

The year’s whirlwind of astonishing events began with the sudden appearance of mysterious drone swarms over the US in late 2024, even hovering above the New Jersey golf course of presidential hopeful Donald Trump.

The New Jersey drone sightings 

The strange drone activity on the East Coast kicked off in November 2024, prompting hundreds of reports to flood the Unidentified Aerial Phenomena (UAP) tracking platform, Enigma Labs, before 2025 got underway.

As the new year dawned, these perplexing sightings persisted, ultimately leading the Federal Aviation Administration (FAA) to impose a temporary restriction on drone flights across 22 towns in New Jersey by January.

The ban did little to stop the sightings, with many Americans spotting ‘car-sized drones’ making no noise as they invaded the airspace of local military bases and Trump’s property.

On his first day back in the Oval Office, Trump said he would start investigating the mysterious drone activity and put his chief of staff, Susie Wiles, on the case.

The eventual reveal by the White House raised more questions than answers, as the president declared that the drones were ‘not the enemy’ and had been authorized by the US government to conduct ‘research.’

In fact, the FAA failed to mention that drones had been cleared to conduct this alleged research and claimed the objects were ‘lawful commercial drones and helicopters.’

To this day, the origin of the drone swarms, their targets over New Jersey and the rest of the East Coast, and their research remain a mystery.

However, an unnamed private firm contracted by the US military eventually took responsibility for the mysterious drone swarms, claiming they were conducting tests of their advanced aerial craft, according to off-the-record comments at an Army summit in August 2025.

The Buga sphere

Just weeks after the US drone swarm crisis, an alleged alien probe in South America was not only caught on video, but was recovered from a crash site in Colombia.

Named the Buga sphere, after the city it flew over in March, the strange hovering object was seen striking a power line and landing in a field, where local David Velez el Potro found it and refused to hand it over to the Colombian government.

Scientists who examined the alleged space probe found that it contained a maze of fiber-optic wires and emitted some form of energy that killed the soil and grass it touched and made people sick.

It was also covered in symbols that researchers compared to ancient scripts, including runes, Ogham, and Mesopotamian writing systems – although some skeptical scientists have dismissed the object as an elaborate art project.

Eventually, the Buga sphere was taken to Mexico City for further study by ufologists and other scientists. 

In June, Dr Steven Greer, an American ufologist and retired physician, claimed on X that ‘fake policemen’ attempted to enter the vault where the suspected UFO was being kept.

Since then, little information has been released about the Buga sphere, which researchers have called the first UFO recovered by private citizens and solely controlled by non-government scientists.

Interstellar object 3I/ATLAS

In the summer of 2025, another alleged alien visitor quickly moved into our solar system, marking only the third recorded object to enter our system from elsewhere in the cosmos.

The interstellar object 3I/ATLAS was discovered in early July, with most astronomers quickly moving to declare the visitor a comet, a fast-moving ice ball from a distant solar system.

NASA and the European Space Agency have both declared 3I/ATLAS a comet, but have been criticized for their lack of high-quality images of the space rock compared to photos taken by amateurs using backyard telescopes. 

Moreover, esteemed Harvard physicist Avi Loeb pointed out that the object was no ordinary comet, revealing at least 12 different abnormalities that suggested that the three-mile-long object may have been artificially created by an alien intelligence.

Those clues included having a comet’s tail which is facing in the wrong direction of the sun, known as an anti-tail, suggesting the stream is actually exhaust from an engine that’s guiding the object through space.

‘There are still many unresolved anomalies of 3I/ATLAS. Each of these anomalies has less than a percent random chance and no explanation so far,’ Loeb told the Daily Mail on Wednesday.

Loeb added that there’s still more time to find out the true origins of 3I/ATLAS, which will pass Jupiter on March 16, 2026.

It has strangely shifted its course to perfectly align with the Lagrange points of Jupiter, a ‘parking spot’ in space where the gravity of the sun and Jupiter cancel each other out, so the object is not pulled apart.

‘It would be interesting to check whether 3I/ATLAS releases any devices as satellites at the Lagrange points,’ Loeb added.

‘Vast city’ under Egypt’s Giza pyramids

A discovery that has been unfolding all year may rewrite the origins of the ancient Egyptians forever. 

In March, Italian researchers claimed to have uncovered ‘a vast underground city’ which stretches more than 4,000 feet directly underneath the Pyramids of Giza, making them 10 times larger than the pyramids themselves.

The bombshell claim, which many experts claim to have already debunked, came from a study that used radar pulses to create high-resolution images deep into the ground beneath the structures, the same way sonar radar is used to map the depths of the ocean.

In July, the same team identified a colossal vertical shaft leading to two chambers below the Sphinx.

While mainstream archaeologists have slammed the work as unscientific and speculative, the team insists their latest scans point to something extraordinary.

However, the physical proof that these structures really exist has not been presented yet, and answers to what their mysterious purpose may have been did not come in 2025.

Heading into 2026, the research team is hoping to receive permission to dig under both major structures to find traces of the hidden city. They’ve also submitted a formal proposal for non-invasive access, such as clearing existing shafts at the site.

US government weighs UFO and alien disclosure

This year also brought multiple bombshells when it comes to the discussion over UFOs and extraterrestrial life, with the US government reportedly moving closer than ever before to full disclosure of classified reports on aliens.

In September, a panel of US military veterans testified before Congress as whistleblowers into the activities of secret government programs that allegedly had proof that UFOs and extraterrestrials were real.

In one shocking video, the public was shown a US military drone actually firing a Hellfire missile at a UFO, only to see the weapon harmlessly bounce off the extremely advanced craft. 

Congressman Eric Burlison of Missouri revealed video of a US military drone striking an orb-shaped UFO with a missile, which bounced off and did not stop the craft

Since the hearing, Vice President JD Vance doubled down on a promise to ‘get to the bottom of’ the existence of alien life.

In November, a bombshell documentary called ‘The Age of Disclosure’ was released, which interviewed a plethora of high-ranking government officials, detailing the alleged 80-year global cover-up of alien life and the technology humans have created using pieces of crashed UFOs.

While the US military has maintained that America has no evidence aliens or UFOs exist, the odds of President Trump revealing what he knows about the topic suddenly skyrocketed in December, leading experts to believe full public disclosure is just days away.
