World UFO Day: 6 scientific reasons UFO sightings may fool your eyes

Many viral UFO videos create the impression of incredible speed. A zoomed-in camera following a distant object can exaggerate its movement because the background appears to race past. This optical effect, called parallax, often makes aircraft, drones, or balloons look far faster and more erratic than they really are.

Infrared cameras record heat instead of visible light. Strong heat sources can overwhelm the sensor, turning ordinary objects into bright, featureless circles. This is why military or night-vision footage sometimes shows glowing UFO-like objects with no visible wings, edges, or other details.

Hot and cold layers of air bend light in different ways. This can make distant aircraft, buildings, or lights appear to float, stretch, split, or change shape. Pilots and people on the ground have reported unusual sightings that were later linked to these atmospheric effects.

Bright lights at night sometimes bounce around inside a camera lens, producing extra lights that seem to move with the original object. These reflections, known as lens ghosts, can look convincing in videos. Investigators always check for this possibility before treating footage as evidence of an unidentified object.

A single photo or video rarely tells the full story. Researchers compare footage with radar records, other cameras, flight data, and electronic signals before drawing conclusions. Matching evidence from several independent sources gives investigators a much clearer picture of what actually appeared in the sky.

Before deciding a video shows a genuine UFO, ask a few simple questions. Is the camera zoomed in? Could the weather distort the view? Does the object appear on radar or in footage from another source? These checks help separate unusual aerial events from common optical and camera effects.
