Explanation:
Taken on July 29 and July 30,
a registered and stacked series of exposures creates
this dreamlike view of a
northern summer night.
Multiple firefly flashes streak across the foreground as
the luminous Milky Way arcs above the horizon in
the Sierra de crganos national park of central Mexico,
The collection of bright streaks aligned across the
sky toward the upper left in the timelapse image
are Delta Aquariid meteors.
Currently active, the annual
Delta Aquarid meteor shower
shares August
nights though, overlapping with the better-known
Perseid meteor shower.
This year that makes post-midnight, mostly moonless skies in
early August very popular with late night skygazers.
How can you tell a Delta Aquariid
from a Perseid meteor?
The streaks of Perseid meteors can be traced back to
an apparent radiant in the constellation Perseus.
Delta Aquariids appear to emerge from the more southerly
constellation Aquarius, beyond the top left of this frame.
Of course, the bioluminescent flashes of fireflies are common
too on these northern summer nights.
But how can you tell a firefly from a meteor?
Just try to catch one.
