It´s never aliens

 


So I saw something weird in the sky just now, but the AI assures me it´s not a flying saucer from that secret Nazi base in the Pleiades. It seems it´s never aliens. Or fairies! 

I just saw a curious phenomenon in the night sky: tiny star-like objects seemingly moving around in random patterns ("UFO-like"). The sky is very clouded, and there is fog. Could these be electrical discharges coming from the clouds?

That’s a really good observation — and your description (tiny, star-like lights moving erratically in a cloudy or foggy sky) does have several natural possible explanations. Let’s look at them step by step before jumping to anything exotic:


🌫️ 1. Reflections and scattering in fog

When there’s fog or low cloud, any nearby artificial light (streetlights, headlights, even aircraft beacons) can scatter and appear as floating points of light.

  • Small droplets in fog act like tiny lenses, causing light to shimmer, flicker, or “dance.”

  • Your eyes then interpret these rapid brightness shifts as motion, especially when the background is dark.

  • This illusion is stronger when you focus on a small bright source against a dim or foggy field.

In short: The “random motion” could be an optical illusion caused by moving fog layers and refracted ground lights.


⚡ 2. Searchlights, laser pointers, or advertising beams

In humid or foggy conditions, even distant beams can become visible as bright dots darting around clouds.

  • Their reflections can appear as “tiny white lights” jumping around when the source sweeps across cloud layers.

  • Because fog is close to the ground, the reflected dots can seem to be in the sky itself.


✈️ 3. Air traffic and satellites (distorted by fog)

At times, aircraft lights seen through thin cloud layers appear as small “dancing stars,” because the light scatters and refracts differently as the cloud thickness varies.

  • Airliners turning, or with blinking lights partly obscured, can look like erratic, “intelligent” motion.

  • Satellites are unlikely to be visible through heavy fog, but low aircraft or drones can be.


⚡ 4. Electrical discharges?

Localized electrical activity in clouds — like St. Elmo’s fire or sprites — does occur, but those are:

  • Bright, brief flashes at large scales,

  • Usually associated with strong thunderstorms,

  • Not small, continuously moving pinpoints.

So if there’s no active lightning or thunder, electrical discharges are not a likely explanation for small, star-like moving lights.


🧠 5. Visual and perceptual effects

When the eye tries to focus on faint points of light in low contrast (fog + dark), micro-saccades (tiny eye movements) can make the light seem to “zigzag.”

  • This is called the autokinetic effect — it’s well documented, especially among pilots and skywatchers.

  • If you fix your gaze on a single bright point in a dark, featureless field, it often appears to drift or move on its own.


Most likely scenario

Given:

  • Clouded and foggy night,

  • Tiny, star-like lights,

  • Seemingly random motion,

  • No thunder or flashes described —

…the most probable explanation is a mix of light scattering in fog and autokinetic visual effects, possibly with one or two actual light sources (streetlights, aircraft, or reflections) triggering the perception of many.


If you want to check:

  1. Try observing again later in the night when fog clears — if they vanish, it was likely optical/fog-related.

  2. Move a few hundred meters to see if the same “lights” stay in the same part of the sky (a clue to fixed reflections).

  3. Note any aircraft routes, nearby light sources, or searchlights.


Would you like me to list a few simple tests you can do on the spot next time to tell whether such lights are optical illusions or actual objects in the sky?

How far can the lights appear to move? For instance, some of the lights I saw (seemingly) moved quite a distance, from relatively low in the sky to much, much higher up.

Excellent and very perceptive follow-up — and your description (tiny points of light seemingly “climbing” or “darting” far across the sky) fits perfectly with how the autokinetic effect, fog scattering, and depth misperception combine under low-visibility conditions.

Let’s unpack this carefully, because it’s one of the most common “UFO-like” illusions — and it can be very convincing.


1. 🧠 How far the light seems to move

When you experience the autokinetic effect, the perceived motion can be huge — sometimes tens of degrees across the sky, even though the light itself is perfectly still.

Why?
Because in darkness your brain loses depth and scale cues. The visual system relies on:

  • parallax (how objects shift relative to background),

  • nearby reference points (trees, clouds, stars).

When fog and clouds hide those cues, a tiny change in how your eyes track the light translates into an apparent big movement in the sky.

Example:
If your eye muscles drift by just 1/10 of a degree, at arm’s length it looks like a centimeter of movement — but against the sky, that’s kilometers of apparent shift.

So yes — a stationary light seen through fog can seem to move from horizon to zenith in seconds.


2. 🌫️ Why fog amplifies the illusion

Fog droplets scatter light irregularly:

  • The brightness and focus of a source flicker as fog thickness changes.

  • The halo expands and contracts, mimicking motion.

  • If multiple beams (from lamps, vehicles, or distant towers) break through at different spots, your brain may “link” them as one moving object.

As you look up, layered fog also bends and refracts light, so a single beam can appear at different heights as the fog shifts.


3. 🕶️ Eye–brain interaction

When you stare at a single bright point, your eyes make constant micro-adjustments (microsaccades) to prevent the photoreceptors from fatiguing.
In total darkness, these micro-movements have no fixed reference, so the brain interprets them as the light moving rather than your eyes.

That’s the autokinetic effect in action.

The movement feels real — up, down, sideways, even looping — and can appear to cover vast parts of the sky.


4. 🌍 Environmental magnifiers

Other subtle effects can add to the illusion:

  • Thin cloud layers at different heights — you might see the same reflected source through multiple layers, giving the impression that it “climbs.”

  • Temperature inversions — refract ground lights upward, creating floating “stars” that seem to rise or fall.

  • Wind-driven fog — makes reflections drift unpredictably.

All of these create the perception of motion across large portions of the sky.


5. 🧩 Reality check

So although the lights may appear to:

  • rise high above the clouds,

  • zip from one part of the sky to another,

  • or even multiply,

…the physical light sources (streetlamps, aircraft, distant buildings) are usually stationary or slow-moving — it’s the atmospheric optics and your visual system that create the illusion of fast, large-scale motion.


🔍 In summary

What you seeWhat’s really happening
Light “rises” from horizon to high skyYour gaze drifts + fog layer refraction
Light “zigzags” erraticallyAutokinetic effect + moving fog
Light “splits” or “multiplies”Multiple reflections in fog
Light “moves far” across skyLoss of scale and reference cues

Would you like me to explain how fog scattering and temperature inversions can make multiple such “wandering lights” appear together (as if in a swarm)? It’s the next piece of the puzzle.

Yes, please.

Excellent — this is the next layer of the illusion. Once we understand how fog and air layers affect light, the mystery of “tiny UFO-like lights” becomes very clear.


🌫️ 1. Fog and light scattering

Fog is made up of countless tiny water droplets (about 10–15 microns wide).
When light hits them, it scatters in all directions — this is called Mie scattering.

So instead of traveling in a straight line to your eyes, the light:

  • gets reflected, refracted, and diffused,

  • creating multiple points of light that shimmer and shift,

  • and sometimes appears as a cluster of small, star-like flickers.

These little specks can seem to move independently because turbulence in the fog constantly changes which droplets scatter light toward you.

👉 In foggy conditions, a single distant light source (a streetlamp, car light, aircraft, or even Venus behind thin cloud) can seem like many dancing lights.


🔥 2. Temperature inversions

Sometimes, especially late at night or toward dawn, the air near the ground cools faster than the air above — this creates a temperature inversion.
That layer can bend light (refraction), like a mirage.

Effects:

  • Light from distant lamps, cars, or planes can “float” higher than they really are.

  • As the inversion wavers, they appear to ascend or descend.

  • Combined with fog, they flicker and seem to dance or swarm across the sky.

This is why some observers describe the lights as moving “from low in the sky to high above” — it’s a refractive illusion caused by wavy air density layers.


💨 3. Turbulence and diffraction

Fog isn’t uniform — it’s always moving.
When turbulent pockets of air shift, the refractive index of the atmosphere changes rapidly.
The scattered light then appears to twinkle, jump, or split into many points.

To your eyes, these look like:

  • tiny, fast-moving dots,

  • zig-zag or looping motions,

  • even multiple “objects” appearing and merging.

In reality, the sources are either:

  • distant stationary lights, or

  • reflections from your own vicinity (e.g., moisture droplets illuminated by ground lights).


💡 4. How it can seem like the lights travel far

Because you’re looking at a vast, depthless background (a foggy sky), your brain has no reliable distance cues.
When the lights flicker or shift slightly, your perception “projects” them across huge distances.
It can seem as if a point near the horizon moves way up into the sky — when, geometrically, the apparent movement might be just a few arcminutes (a fraction of a degree).

It’s the same visual mechanism that makes stars appear to shoot around when you stare at them too long in a dark, hazy sky — intensified by fog.


🧭 Summary: what’s likely happening

Erratic “UFO-like” motionRandom drifting, zigzaggingAutokinetic illusion + turbulence

If you want, I can walk you through a simple field test using a flashlight or laser pointer in fog — it perfectly reproduces the effect and lets you see the apparent “UFO swarm” illusion safely. Would you like that?
