Last week when the Leonid meteor shower was underway, Joel Bavais of Ath, Belgium, grabbed his camera and went outside, looking for shooting stars. This is what he saw: 
"I took the picture by putting my camera on a garden table and pointing it straight up," says Bavais. "The streaks of light were almost directly overhead."
Were they Leonids? Cosmic rays? UFOs?
"None of the above," says atmospheric optics expert Les Cowley. "These are urban light pillars."
He explains: "That night above Ath there was an icy fog full of flat plate crystals. The tiny crystals mirrored the lights of the city beneath into sets of light pillars. The higher the crystals, the closer the reflection glints approached the zenith making the pillars appear to converge overhead: illustration. Why the breaks in the lines of light? There were several layers of ice crystals with gaps between them."
