Explanation:
Sometimes, during a
total eclipse of the Sun, a
strange shadow of darkness
can be seen stretching off into the distance.
Called a shadow cone, they are visible because the
Earth's atmosphere is not completely transparent,
scattering sunlight and hence
appearing blue during the day.
Shadow cones are particularly dramatic for
eclipses near the horizon,
as geometry creates a long corridor of sun-blocked air.
Visible above
is a shadow cone caught during a
total solar eclipse
visible last month from South
Australia.
The eclipsed Sun
itself still appears bright because of light from the
surrounding corona.
The digital camera on the left is zoomed in to show a
better image of the actual eclipse.
