This
spectacular composite photo of the May 9 annular solar eclipse above
Western Australia brilliantly shows the progress of the moon's shadow as
it crosses the disk of the sun. The passage produces the famous "ring
of fire" effect seen in such events, where the width of the moon as seen
from Earth doesn't completely cover the sun during an otherwise total
eclipse.
