Sunrise over the Parthenon

Today, (June 21st) the sun will stay in the sky longer than any other day of the year, as seen
from the northern hemisphere of Earth. Named the Summer Solstice, today's maximum daylight
is indicative of the high amount of sunlight this time of year that is primarily responsible
for the heat of the summer season. At the north pole and for all places above the arctic circle,
there will be no night -- the entire day today will be lit by sunlight. The situation is reversed
in Earth's southern hemisphere, where today has the least sunlight of any day. Today's solstice
is commemorated above by a well-planned picture of our five billion year old Sun rising behind
the 2,500 year old Parthenon in Greece.
