Explanation:
On the night
of August 12, this bright Perseid meteor
flashed above volcanic Sunset Crater National Monument, Arizona, USA,
planet Earth.
Streaking along the summer Milky Way, its initial color
is likely due to the shower meteor's
characteristically high speed.
Entering at 60 kilometers per second, Perseid meteors
are capable of exciting green
emission from oxygen atoms while passing through the
tenuous atmosphere at high altitudes.
Also characteristic of bright meteors, this Perseid left
a visibly glowing persistent train.
Its evolution is seen over a three minute sequence (left to right)
spanning the bottom of the frame.
The camera ultimately captured a dramatic
timelapse video of the twisting,
drifting train.
