Explanation:
Part of the Sun disappeared behind the Moon earlier this week.
Previously, the
waning Moon was best visible from all places on
Earth during the early
morning hours because it trailed the Sun.
As the Moon orbited the Earth, however,
it caught up to the Sun and passed it on the sky.
Now the
waxing Moon leads the Sun and is
therefore best visible just after sunset.
Each month, as viewed from the Earth, the Moon laps the Sun and the
cycle repeats.
Sometimes when the
Moon passes the Sun,
it goes directly in front of part of it, causing a
partial eclipse.
Pictured above, a time lapse sequence shows the
Moon passing the Sun on June 10 behind the
Golden Gate Bridge in San Francisco,
California,
USA.
