Explanation:
Tonight the
Perseid Meteor Shower reaches its maximum.
Grains of icy rock will streak across the sky as they evaporate during entry into
Earth's atmosphere.
These grains were shed from
Comet
Swift-Tuttle.
The Perseids result from the annual crossing of the Earth
through
Comet Swift-Tuttle's orbit, and are
typically the most active
meteor
shower of the year.
Although it is hard to predict the level of activity in any meteor shower, in a clear
dark sky an observer might see a
meteor a minute.
This year's
Perseids occur just
before a
new Moon
and so the relatively dark sky should make even faint meteors visible.
Meteor showers in general are best be seen from a
relaxing position, away from lights.
