Anomaly in Saturn's Rings

In the latest batch of images from the Cassini probe investigating Saturn, one

of them shows, quite distinctly, a small object piercing the F ring of debris that surrounds Saturn. There's a picture of the bifurcated ring to the left there; click it for a larger image. It looks very much as if something small has cut a path through the dust in Saturn's F ring, moving through the ring from below, and leaving a trail of dust particles in its wake.

Perseids Meteor Shower: Tonight's the Night

Tonight is the "best" night, in terms of sheer numbers of visible meteors per hour,

to see the Perseids. The Perseids are the dust and debris from the Comet Swift-Tuttle, and an annual August event. The moon will be fairly bright; it's a 55% Gibbous moon, so you'll want to avoid looking directly at the moon, since it's just as much a distracting source of light pollution as city and traffic lights are.
