Explanation:
Did you ever get caught in a meteor shower?
If yes, then every minute or so the sky sparked with fleeting flashes of light.
This was the fate of the pictured astrophotographer during last year's Perseids
meteor shower.
During the featured three-hour image composite,
about 90 Perseids rained down above Lake Duolun of
Inner Mongolia,
China.
If you trace back the meteor streaks, you will find that most of them
appear to radiate from a single constellation -- in this
case
Perseus.
In fact, you can even tell which meteors are not
Perseids because they track differently.
Tonight promises to be another good night to get caught in a meteor shower because
it is the peak for the Geminids.
Gemini, the shower radiant,
should rise shortly after sunset and
be
visible most of the night.
