Explanation:
To see the feathered serpent
descend
the Mayan pyramid requires exquisite timing.
You must visit
El Castillo -- in
Mexico's
YucatAn Peninsula -- near an
equinox.
Then, during the late afternoon if the sky is clear,
the pyramid's own
shadows create triangles
that merge into the famous illusion of the
slithering viper.
Also known as the
Temple of Kukulkan, the impressive step-pyramid stands 30 meters tall and 55
meters wide at the base.
Built up as a series of square terraces by the
pre-Columbian civilization between the 9th and 12th century,
the structure can be used
as a calendar and is noted for
astronomical alignments.
To see the central band of our
Milky Way Galaxy descend overhead the
Mayan pyramid,
however, requires less exquisite timing.
Even the
ancient Mayans
might have been impressed, though, to know that the exact positions of the Milky
Way, Saturn (left) and Jupiter (right) in the featured image give it a time stamp
more specific than
equinox -- in fact 2019 April 7 at 5 am.
