These
holes look like big trilobites in the sky, or maybe they could be
called “skylobites.” This picture of failstreak holes over Florida was
posted by redditor deadhalo. They are sometimes attributed to UFOs, but there’s a perfectly logical explanation from meteorology.
Failstreak holes
are the beginning of ice formations in clouds. The temperature can be
very cold before water vapor turns to ice. When ice crystals begin to
form, the crystallization spreads outward in a domino effect. Meanwhile,
water surrounding the ice crystals evaporates, leaving a big hole.
