These scenes aren’t fantasy ... they’re rare alignments of light, moisture, ice crystals, electricity, and perspective. Rainbows form when sunlight refracts and reflects inside raindrops. Halos appear when light bends through hexagonal ice crystals high in the atmosphere. Lightning traces the fastest path through charged air, sometimes carving patterns that look deliberate ... but aren’t. | AstroNature

Vertical columns of light shooting skyward from Toronto's CN Tower—this is ice crystal magic at its coldest. Light pillars form when city lights reflect off millions of flat hexagonal ice crystals suspended in freezing air below -15°C. Each crystal acts as a tiny mirror, creating vertical shafts of reflected light that can extend 100 feet above their source. Unlike halos that require the Sun or Moon, light pillars need only cold temperatures and diamond dust fog. Toronto's skyline produces dozen

As water freezes, its molecules slow down, lose energy, and align into a hexagonal structure, forming ice. This unique arrangement makes ice less dense than liquid water, allowing it to float—a vital feature for life in aquatic ecosystems during winter. ❄️ | The Galactic Void
