Sprites, elves, trolls, gnomes, and pixies!
From the NYT Science Times yesterday (9/30), “On the Hunt for a Sprite on a Midsummer’s Night” [oh, the rhyme; science writing has tons of language play] by Sandra Blakeslee, beginning:
Armed with sensitive cameras and radio telescopes, [Thomas] Ashcraft hunts for sprites — majestic emanations of light that flash for an instant high above the thunderheads, appearing in the shapes of red glowing jellyfish, carrots, angels, broccoli, or mandrake roots with blue dangly tendrils. (Weather buffs call the tall, skinny ones “diet sprites.”) No two are alike.
And they are huge — tens of miles wide and 30 miles from top to bottom. But because they appear and vanish in a split-second, the naked eye tends to perceive them only as momentary flashes of light. It takes a high-speed camera to capture them in detail.
