The only place without shadow
The sun itself shows you
where its rays at this moment
are vertically touching the earth.
The location of the luminous point on
the globe shows us where the sun is at
its zenith (sub-solar point). At this very
moment, this is the only place on earth
where no shadow falls. You can follow the
sun's path across our planet every day,
all year round, in real time.
