Throughout the years, reports of alien abductions have emerged from all corners of the globe.
An alien abduction is generally described as an event in which individuals report being taken against their will by extraterrestrial beings, often undergoing various forms of physical and psychological experimentation.
Some argue that these experiences could simply reflect the subconscious mind at work or suggest that the abductees may have unknowingly been subjects of classified military experiments. Nonetheless, many abductees share accounts with such remarkable detail and consistency that some researchers feel the phenomenon deserves serious consideration.
Over time, I’ve shared numerous articles on cases of alleged alien abductions, which you can explore under the "alien abduction" tag below the article.
Here are two more intriguing cases in which abductees recount their experiences in vivid detail, prompting us to seriously consider the possibility that people may actually be taken by aliens.
The Betty Andreasson Alien Abduction: A Strange Encounter in 1967
One of the most detailed and haunting accounts of alien abduction began on January 25, 1967, in South Ashburnham, Massachusetts. That evening, Betty Andreasson’s family experienced a power outage, followed by an eerie red light outside. Peering out, Betty’s father saw five strange beings approaching who soon entered the house, seemingly passing through solid walls. They communicated telepathically and temporarily froze the family in place.
These beings had distinctive appearances, with pear-shaped heads, wide eyes, and a calm, almost friendly aura. Betty was led to a spacecraft in her backyard and taken aboard, where she underwent strange tests and experienced an otherworldly vision. Hours later, she was returned home, and the aliens left her family unharmed. Initially, Betty viewed her experience through a religious lens, but over time, she came to see it as an alien encounter.
Years later, her story caught the attention of Dr. J. Allen Hynek, a leading UFO researcher. Under hypnosis, Betty’s fragmented memories resurfaced, revealing consistent details corroborated by her daughter, who had also been briefly unfrozen by the beings. After extensive testing and interviews, investigators concluded that Betty was credible and sincerely believed in what she described. The Betty Andreasson abduction remains one of the most compelling cases in UFO lore.
The 1974 Medicine Bow National Forest Abduction: Carl Higdon's Astonishing Encounter
Carl Higdon's hunting trip to Wyoming’s Medicine Bow National Forest in October 1974 took a surreal turn when he experienced one of the most bizarre UFO abduction cases on record. Aiming at an elk, Higdon was stunned to see his bullet slow mid-air and drop, seemingly defying physics. Moments later, he noticed an unusual figure—a tall being in a black jumpsuit with rod-like appendages instead of hands—who offered him pills, claiming that one would sustain him for days.
Higdon, inexplicably compliant, swallowed a pill and suddenly found himself in a transparent structure with two more beings and five frozen elk. He was told they were traveling 163,000 light-years away to the aliens' home planet, which he described as filled with towering structures and an intensely bright sun.
Two and a half hours later, Higdon was back in Medicine Bow, disoriented and missing his elk. Later medical tests revealed inexplicably high vitamin levels and the disappearance of old lung scars. Adding credibility to his story, other witnesses reported seeing strange lights in the area. Higdon’s experience remains a mysterious case.

NASA’s Voyager 2 captured this image of Uranus while flying by the ice giant in 1986. New research using data from the mission shows a solar wind event took place during the flyby, leading to a mystery about the planet’s magnetosphere that now may be solved.NASA/JPL-Caltech NASA’s Voyager 2 flyby of Uranus decades ago shaped scientists’ understanding of the planet but also introduced unexplained oddities. A recent data dive has offered answers.
When NASA’s Voyager 2 spacecraft flew by Uranus in 1986, it provided scientists’ first — and, so far, only — close glimpse of this strange, sideways-rotating outer planet. Alongside the discovery of new moons and rings, baffling new mysteries confronted scientists. The energized particles around the planet defied their understanding of how magnetic fields work to trap particle radiation, and Uranus earned a reputation as an outlier in our solar system.
Now, new research analyzing the data collected during that flyby 38 years ago has found that the source of that particular mystery is a cosmic coincidence: It turns out that in the days just before Voyager 2’s flyby, the planet had been affected by an unusual kind of space weather that squashed the planet’s magnetic field, dramatically compressing Uranus’ magnetosphere.
“If Voyager 2 had arrived just a few days earlier, it would have observed a completely different magnetosphere at Uranus,” said Jamie Jasinski of NASA’s Jet Propulsion Laboratory in Southern California and lead author of the new work published in Nature Astronomy. “The spacecraft saw Uranus in conditions that only occur about 4% of the time.”
The first panel of this artist’s concept depicts how Uranus’s magnetosphere — its protective bubble — was behaving before the flyby of NASA’s Voyager 2. The second panel shows an unusual kind of solar weather was happening during the 1986 flyby, giving scientists a skewed view of the magnetosphere.NASA/JPL-Caltech Magnetospheres serve as protective bubbles around planets (including Earth) with magnetic cores and magnetic fields, shielding them from jets of ionized gas — or plasma — that stream out from the Sun in the solar wind. Learning more about how magnetospheres work is important for understanding our own planet, as well as those in seldom-visited corners of our solar system and beyond.
That’s why scientists were eager to study Uranus’ magnetosphere, and what they saw in the Voyager 2 data in 1986 flummoxed them. Inside the planet’s magnetosphere were electron radiation belts with an intensity second only to Jupiter’s notoriously brutal radiation belts. But there was apparently no source of energized particles to feed those active belts; in fact, the rest of Uranus’ magnetosphere was almost devoid of plasma.
The missing plasma also puzzled scientists because they knew that the five major Uranian moons in the magnetic bubble should have produced water ions, as icy moons around other outer planets do. They concluded that the moons must be inert with no ongoing activity.
Solving the Mystery
So why was no plasma observed, and what was happening to beef up the radiation belts? The new data analysis points to the solar wind. When plasma from the Sun pounded and compressed the magnetosphere, it likely drove plasma out of the system. The solar wind event also would have briefly intensified the dynamics of the magnetosphere, which would have fed the belts by injecting electrons into them.
The findings could be good news for those five major moons of Uranus: Some of them might be geologically active after all. With an explanation for the temporarily missing plasma, researchers say it’s plausible that the moons actually may have been spewing ions into the surrounding bubble all along.
Planetary scientists are focusing on bolstering their knowledge about the mysterious Uranus system, which the National Academies’ 2023 Planetary Science and Astrobiology Decadal Survey prioritized as a target for a future NASA mission.
JPL’s Linda Spilker was among the Voyager 2 mission scientists glued to the images and other data that flowed in during the Uranus flyby in 1986. She remembers the anticipation and excitement of the event, which changed how scientists thought about the Uranian system.
“The flyby was packed with surprises, and we were searching for an explanation of its unusual behavior. The magnetosphere Voyager 2 measured was only a snapshot in time,” said Spilker, who has returned to the iconic mission to lead its science team as project scientist. “This new work explains some of the apparent contradictions, and it will change our view of Uranus once again.”
Voyager 2, now in interstellar space, is almost 13 billion miles (21 billion kilometers) from Earth.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Perseverance rover captured the silhouette of the Martian moon Phobos as it passed in front of the Sun on Sept. 30, 2024. The video shows the transit speeded up by four times, followed by the eclipse in real time. NASA/JPL-Caltech/ASU/MSSS/SSI The tiny, potato-shaped moon Phobos, one of two Martian moons, cast a silhouette as it passed in front of the Sun, creating an eye in Mars’ sky.
From its perch on the western wall of Mars’ Jezero Crater, NASA’s Perseverance rover recently spied a “googly eye” peering down from space. The pupil in this celestial gaze is the Martian moon Phobos, and the iris is our Sun.
Captured by the rover’s Mastcam-Z on Sept. 30, the 1,285th Martian day of Perseverance’s mission, the event took place when the potato-shaped moon passed directly between the Sun and a point on the surface of Mars, obscuring a large part of the Sun’s disc. At the same time that Phobos appeared as a large black disc rapidly moving across the face of the Sun, its shadow, or antumbra, moved across the planet’s surface.
Astronomer Asaph Hall named the potato-shaped moon in 1877, after the god of fear and panic in Greek mythology; the word “phobia” comes from Phobos. (And the word for fear of potatoes, and perhaps potato-shaped moons, is potnonomicaphobia.) He named Mars’ other moon Deimos, after Phobos’ mythological twin brother.
Roughly 157 times smaller in diameter than Earth’s Moon, Phobos is only about 17 miles (27 kilometers) at its widest point. Deimos is even smaller.
Rapid Transit
Because Phobos’ orbit is almost perfectly in line with the Martian equator and relatively close to the planet’s surface, transits of the moon occur on most days of the Martian year. Due to its quick orbit (about 7.6 hours to do a full loop around Mars), a transit of Phobos usually lasts only 30 seconds or so.
This is not the first time that a NASA rover has witnessed Phobos blocking the Sun’s rays. Perseverance has captured several Phobos transits since landing at Mars’ Jezero Crater in February 2021. Curiosity captured a video in 2019. And Opportunity captured an image in 2004.
By comparing the various images, scientists can refine their understanding of the moon’s orbit to learn how it’s changing. Phobos is getting closer to Mars and is predicted to collide with it in about 50 million years.
More About Perseverance
Arizona State University leads the operations of the Mastcam-Z instrument, working in collaboration with Malin Space Science Systems in San Diego, on the design, fabrication, testing, and operation of the cameras, and in collaboration with the Niels Bohr Institute of the University of Copenhagen on the design, fabrication, and testing of the calibration targets.
A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust).
Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.
NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.
