Have you ever looked up on a frigid night and witnessed beams of light stretching towards the heavens? these aren’t searchlights or celestial phenomena, but rather a captivating atmospheric display known as light pillars. Once considered a rare sight confined to the Arctic, Siberia, or Canada, these ethereal columns of light are now increasingly observed in more temperate regions, including Lithuania, as of January 11, 2026.
Understanding Light Pillars: A Visual Spectacle
Light pillars are an optical phenomenon created when light reflects off tiny ice crystals suspended in the atmosphere. These crystals, typically flat, hexagonal plates, gently drift downwards, aligning themselves horizontally as they fall. This alignment is crucial, as it allows them to act as miniature mirrors, reflecting light sources back towards your eye.
| Feature | Description |
|---|---|
| Cause | Reflection of light off ice crystals |
| Crystal Shape | Flat, hexagonal plates |
| Temperature | Typically below -10°C (14°F) |
| Visibility | Best viewed in dark locations away from bright lights |
I’ve found that the most striking displays occur when the air is exceptionally still, allowing the crystals to maintain their horizontal orientation. The color of the pillar directly corresponds to the light source illuminating it – whether it’s the warm glow of streetlights, the headlights of a car, or even the sun or moon.
the Science Behind the Shine
The formation of light pillars requires specific atmospheric conditions. A temperature of -10°C (14°F) or colder is generally needed to allow these ice crystals to form and remain stable. According to recent studies by atmospheric scientists at the University of Colorado Boulder (published November 2025), the size and concentration of these crystals significantly impact the brightness and clarity of the pillars. Larger concentrations create more vivid displays.
Did you know? Light pillars are part of the halo family, a broader category of optical phenomena caused by ice crystals in the atmosphere.
These pillars aren’t actually “above” the light source; they appear to extend upwards because of the way light is reflected. It’s a perspective trick, a gorgeous illusion created by the physics of light and ice. Think of it like looking at a reflection in a still pond – the image appears to be in the water, but it’s simply a reflection of what’s above.
Observing Light Pillars: Tips for Optimal Viewing
Currently, reports indicate that light pillars are visible in locations like Alytus and other areas across Lithuania, particularly around
