Sky Oddities • Atmospheric Optics • Fog, Cloud & Shadow Phenomena
Glories are atmospheric optical phenomena that appear as colored rings around an observer’s shadow, an aircraft shadow or the antisolar point. They form when sunlight is backscattered and diffracted by tiny cloud, fog or mist droplets.
TL;DR: What Is a Glory?
A glory is a set of colored concentric rings seen opposite the Sun, usually around the observer’s shadow on fog or cloud. Glories are caused by sunlight interacting with tiny water droplets through backscattering, diffraction and wave interference.
The Rainbow Ring Around Your Shadow
A glory can look like a small circular rainbow wrapped around your shadow’s head, a glowing target on cloud tops or colored rings surrounding an airplane’s shadow. It is one of the most beautiful observer-centered optical effects in the atmosphere.
Unlike a normal rainbow, which forms a large arc from raindrops, a glory is compact, circular and centered near the antisolar point — the point directly opposite the Sun from your perspective.
What Causes a Glory?
Glories form when sunlight hits tiny water droplets in fog or cloud and is scattered back toward the observer. The exact physics involves backscattering, diffraction and interference, which create colored rings around the shadow point.
- Sun behind the observer: glories appear opposite the Sun.
- Tiny droplets ahead or below: fog, cloud or mist provides the scattering particles.
- Backscattering: light is redirected back toward the observer.
- Diffraction: light waves bend around droplets.
- Interference: overlapping waves create colored rings.
Where Glories Are Seen
Aircraft Glories
Aircraft passengers often see glories around the plane’s shadow on cloud tops. These appear as colored rings surrounding the aircraft silhouette when the Sun is behind the plane.
Mountain Glories
Hikers and climbers may see glories around their shadow projected onto fog or cloud below. When combined with a giant shadow, this creates the classic Brocken spectre.
Fog Glories
In dense fog, glories can appear around a person’s shadow when sunlight breaks through from behind. These are often subtle but can be striking in uniform droplet conditions.
Cloud-Top Glories
From high viewpoints or aircraft, cloud-top glories can appear as bright rings on a smooth cloud deck below.
Glory vs Rainbow vs Brocken Spectre
| Phenomenon | Appearance | Main Cause | Key Clue |
|---|---|---|---|
| Glory | Colored rings around shadow or antisolar point | Backscattering and diffraction by tiny droplets | Compact circular rings |
| Rainbow | Large colored arc or circle | Refraction and reflection in raindrops | Large bow opposite the Sun |
| Brocken spectre | Giant shadow on fog or cloud | Observer shadow projected onto mist | Human-like shadow moves with you |
| Fogbow | Pale white bow | Light interacting with tiny fog droplets | Large faint white arc in fog |
Why Glories Form Colored Rings
Glories are not ordinary miniature rainbows. Their rings are produced by wave effects around tiny droplets. Light waves bend, scatter and interfere, producing alternating bright and dark colored bands.
Droplet size matters. More uniform droplet sizes can create clearer rings, while mixed droplet sizes blur the glory and make the colors less distinct.
How to Recognize a Glory
- The Sun is behind you.
- You are looking toward fog, mist or cloud droplets.
- Colored rings appear around your shadow, an aircraft shadow or the antisolar point.
- The rings are usually compact and circular.
- The effect often appears from aircraft, mountains, cliffs or foggy terrain.
- It may appear together with a Brocken spectre.
Why Glories Are Mistaken for Portals, Halos or Paranormal Signs
Glories look strange because they appear centered on the observer’s shadow. That makes them feel personal, as if the sky has selected you for a suspicious atmospheric ceremony.
But a glory is a natural light effect. The colored rings are created by sunlight interacting with tiny droplets, not by portals, energy fields or the universe giving your shadow a personal brand identity.

Glories FAQ
What is a glory?
A glory is a set of colored rings that appears around the observer’s shadow or the antisolar point when sunlight is backscattered by tiny cloud or fog droplets.
What causes a glory?
A glory is caused by sunlight interacting with tiny water droplets through backscattering, diffraction and wave interference.
Where are glories most often seen?
Glories are often seen from aircraft, mountains, cliffs or high viewpoints when the Sun is behind the observer and clouds or fog lie below or ahead.
Is a glory the same as a rainbow?
No. A rainbow is caused mainly by refraction and reflection in larger raindrops, while a glory is caused by backscattering and diffraction in tiny droplets.
Why do glories appear around aircraft shadows?
Aircraft glories appear when the plane’s shadow falls on clouds below and sunlight is scattered back toward the passenger by tiny cloud droplets.
Are glories dangerous?
No. Glories are harmless atmospheric optical phenomena caused by sunlight and droplets.
