Nature is full of surprises; when we think we’ve seen and know it all, she injects strange things that even science, though indeed powerful, can’t fully explain. These are actual natural phenomena, but they seem straight out of science fiction or a horror film, and many have mistaken them for UFOs or angry gods in action. From sparkling water bodies to bloody waterfalls, discover the top 10 natural phenomena that seem supernatural.
Bioluminescent Bays
Imagine taking a stroll by the beach, stepping into the surf, and suddenly the sea bursts into a sparkling neon blue. This is bioluminescence, one of the rarest natural wonders in the world. You can only experience it in a few locations, known as Bioluminescent Bays.
So, what makes the water glow? These magnificent bays boast numerous microscopic planktons called dinoflagellates, which produce the glow when the sea is disturbed.
The sight is surreal; the waves sparkle, footprints glimmer, and boats leave a trail of glistering display. This often creates a romantic atmosphere, making swimming in these bays one of the best things to do for couples.
- Where to see them: Mosquito Bay (Vieques, Puerto Rico), Laguna Grande (Fajardo, Puerto Rico), La Parguera (Lajas, Puerto Rico)
- When to see them: They are best witnessed a week before or after the new moon.
Ball Lightning
You’re cozying in a room, and a sparkling orb shows up, floats, lasts a few seconds, and mysteriously disappears with a pop! You might think you’re hallucinating. Well, you may have just experienced ball lightning, one of the most interesting natural phenomena.
For centuries, this bizarre phenomenon has puzzled scientists and travellers. And so far, no one really understands how it forms. Still, a few theories suggest shimmering spheres of varying sizes and colours, with many eyewitness accounts attesting to their existence.
Some of these spheres have been spotted rolling along the ground, while others pass straight through walls. Is it plasma? An electrical trick? It remains unexplained and highly unpredictable. But if ghosts held parties, this would absolutely be their mirror ball.
- Where to see them: On the ground during thunderstorms, sometimes breaking through windows.
Fire Rainbows
Also known as “mother-of-pearl clouds,” fire rainbows are magnificent but one natural phenomena that seem supernatural. It’s caused by sunlight refracting through ice in high-altitude cirrus clouds. The circumhorizontal arcs are coloured like a rainbow, but are not from actual rainbows or fire, despite their appearance or name. The spectacle is extremely unlikely, and witnessing it will make you feel like a celestial lottery winner!
They occur under two conditions: The cirrus clouds must be present, and the sun must be at a high angle (at least 58° above the horizon).
- Where to see them: They primarily occur in the US, particularly over the Rockies in South Carolina, West Virginia, Idaho, and Texas. They’ve also been spotted in various places in Northern Europe.
- When to see them: Summer, when the sun is at its highest
Blood Falls in Antarctica
@aiwowai Blood Falls — The Creepiest Natural Wonder on Earth 🌍 You’re looking at one of the most bizarre places on Earth — Blood Falls in Antarctica. This red waterfall isn’t fake, and it’s not blood… but the truth behind it is even crazier. Nature is hiding something deep beneath the ice — and it’s leaking out. Would you dare to get this close?

Nothing screams “horror movies” like Antarctica’s Blood Falls. This phenomenon is rarer than the Northern Lights. The unique waterfall isn’t located along the usual cruise routes, and those lucky enough to witness it do so by flying over it.
Why is it called Blood Falls, and what actually happens there? It’s a crimson-coloured cascade flowing out of the Taylor Glacier. As it spills out, it stains the picturesque white ice, giving a ‘stabbed Earth’ scene.
The water comes from a subglacial lake, sealed off for more than 1.5 million years, over 1,300 feet beneath the ice, and is loaded with iron. When iron-rich water comes into contact with air, it rusts, creating the dramatic bloody colour.
According to scientists, the lake supports unusual microbial life, which has survived extreme environmental conditions.
Catatumbo Lightning
Experience a never-ending lightning storm over Lake Maracaibo in Venezuela. The lake witnesses an astonishing 250 lightning flashes per square kilometre annually, which is the world’s highest frequency of lightning strikes.
Referred to as Catatumbo Lightning, it flashes for an average of 9 hours daily, 140-160 nights per year, and up to 40 times per minute. That’s a whopping over a million lightning flashes annually in just one place!
The continuous lightning flashes begin about an hour after dusk and sometimes last up to 10 hours straight.
According to modern scientists, a combination of topography and meteorological factors causes the rare occurrence.
While some indigenous groups believed it originated from spiritual forces, it served as a navigational guide for early explorers, acting as a natural lighthouse. Forget GPS. Just go along with the astonishing, endless lightning display. What a strange, yet incredibly remarkable gift from Mother Nature?
- When to see them: The wet season, between July and November, but the lightning strikes peak in October.
Morning Glory Clouds
No, we aren’t referring to a breakfast menu. Morning Glory Clouds are among the most unique natural phenomena. They are an unusual form of clouds, usually horizontal and cylindrical in shape, possess wave-like motions, and can extend for hundreds of miles.
They are the longest rolling clouds on Earth and are visible at dawn in Australia’s Gulf of Carpentaria, Queensland. Pilots who’ve flown alongside these clouds report it’s like ‘riding a massive, invisible wave’.
Scientists claim the phenomenon is a result of converging weather patterns. If you witnessed the Morning Glory Clouds without this scientific knowledge, you’d think it’s the aliens invading our precious planet.
St. Elmo’s Fire

Elmo’s Fire is a sparkling plasma (corona discharge) caused by strong electric fields on pointed objects, like spires, windmills, and masts.
Some sailors saw the glowing plasma on their ships’ masts as a blessing from St. Erasmus, safeguarding them against storms. Others firmly believed the ghostly light was a bad omen. The sight is spooky enough to chill your spine. After all, when sailing and your ship suddenly bursts into a neon-like glow, you wouldn’t think it’s anything to do with the weather.
It’s definitely one of the natural phenomena that seem supernatural, sometimes producing a crackling or a hissing sound, and it is extremely rare.
Moonbows
Yes, rainbows at night! Also known as a lunar or moon rainbow, a moonbow is a rainbow formed by moonlight rather than sunlight. Because the moon is faint, this unique natural treasure appears ghostly white, as if it’s straight from a supernatural world. You can live your whole life without ever spotting one! That’s how rare the arcs are.
Early folklore portrays them as signs of hope during difficult times, messengers from the gods, and a ghostly portal. All in all, they are proof that Mother Nature can be wonderful and weird simultaneously, and that’s the beauty of it.
- Where to see them: They are best witnessed in Victoria Falls, one of the most beautiful places in Africa to visit at least once, and Cumberland Falls in Kentucky, United States.
Ice Circles
Imagine standing or walking by a frozen river or lake, and suddenly seeing a large slab of ice rolling on the surface. These are Ice Circles, a rare, unexplained natural phenomenon. They are created by eddy currents when they slowly rotate on the water surface, trapping bits of ice, which they then break off, smoothing them into circles. Their sizes vary, but they can reach up to 50 feet wide.
The largest natural phenomena witnessed are larger, like the one seen on the Presumpscot River in Maine in 2019. They look so geometric that locals have mistaken them for extraterrestrials. Sadly, they are less sci-fi, but no less spooky.
- Where to see them: These unusual phenomena have been seen in many cold places across the globe, but they are more frequent in North America and Scandinavia. They’ve also been seen in the UK, Mongolia, and Russia. Maine’s Presumpscot River in Westbrook, Canada’s Taltson River, and North Dakota’s Sheyenne River are the most notable destinations for spotting them.
Hessdalen Lights

Residents of Hessdalen, a remote valley in Norway, have reported mysterious, free-floating lights for many decades. These are the Hessdalen Lights, whose activity skyrocketed when Aage and Rutt Marry Moe witnessed them in 1981. They described what they saw as a “burning fireball” hovering in the evening sky. But reports of these strange lights started in the 1930s, and they’ve puzzled scientists ever since.
They vary in colour, appearing in red, white, and yellow, and sometimes ‘intelligently’ dart around. Many theories attempt to explain how they form, ranging from plasma to piezoelectricity to supernatural forces.
Despite establishing a permanent research station to study the Hessdalen Lights, scientists have never come to a solid explanation for their existence. Whether your theory is science-backed or you view them as UFOs, they are among the eeriest lights on the planet.
From bioluminescent bays to Hessdalen lights, these natural phenomena that seem supernatural continue to blur the line between science and mystery. Even when explained, they still feel almost mystical.
