STRANGE CLOUDS: Sky watchers around the Arctic Circle
are reporting an outbreak of rare Polar Stratospheric
Clouds--super-colorful clouds that sometimes form in the ozone layer

The simultaneous apparition of these strange clouds, poles apart, may be

GEMINIDS PHOTOGRAPHED FROM THE STRATOSPHERE:
When the Geminid meteor shower peaked earlier this week, a snowstorm
was in progress over the mountains of central California. Using a

low-light camera to photograph the shower high above the obscuring
clouds. To see what Geminids look like from the stratosphere, please
