Explanation:
Dusty debris from
periodic Comet Swift-Tuttle
was swept up by planet Earth this week.
Vaporized by their passage through the dense atmosphere
at 59 kilometers per second,
the tiny grains produced a stream of
Perseid
meteors.
A bright, colorful Perseid meteor flash was captured during
this 20 second exposure.
It made its ephemeral appearance after midnight on August 12,
in the moonless skies over the
broad
granite dome of
Enchanted Rock State Natural Area, central Texas, USA.
Below the Perseid meteor, trees stand in silhouette against
scattered lights along the horizon and the faint Milky Way, itself
cut by dark clouds of interstellar dust.
