For a moment, residents and tourists thought they were witnessing something supernatural.
A glowing shape hovered above the horizon near the island of Ikaria, shining brighter than the surrounding sky and slowly changing colors. Phones came out instantly. Social media filled with theories — UFOs, portals, even “signs from the heavens.”
But events like this happen more often than people realize.
The Sky Plays Tricks On Our Eyes
At sunrise and sunset, sunlight passes through thicker layers of atmosphere. Ice crystals, dust, and moisture bend the light in unusual ways. This can create halos, pillars, or glowing discs that appear to float in mid-air.
To the human brain, anything bright and moving without sound feels unnatural — so we interpret it as an object rather than light.
Temperature Layers Create Mirages
Over the sea, warm and cold air stack on top of each other. This bends light dramatically, sometimes lifting distant objects into the sky. Ships, mountains, or even the sun itself can appear stretched, duplicated, or hovering.
This effect is called a superior mirage.
It can look exactly like a glowing craft.
Why It Looks Alive
Small changes in air density cause the light to shimmer and pulse. Your brain reads motion as intention — making the light seem controlled or intelligent.
So What Did People Actually See?
Most likely: sunlight refracted through high-altitude ice crystals combined with a sea mirage.
Rare, beautiful, and a little unsettling — but completely natural.
Sometimes the sky doesn’t show us visitors…
it just reminds us how strange physics can look to human eyes.
