1 Dec., 2008 -- Earthshine

Earthshine. Twice-reflected sunlight. Sunlight is responsible for the slender crescent,
yet the remainder of the moon appears to shine with a dim blush-gray tone. Earthshine is
really sunlight which is reflected off Earth to the moon and then reflected back to Earth.

Venus and Jupiter will next get together again in the morning sky on May 11, 2011. And
ten months later, in March of 2012 they will again pair off in the evening sky right after
sundown. (Information from Space.com)

TV weatherman says it will be 44 years until they converge again with the moon, 2052.

Venus is the bright evening "star" this winter. It's the lower planet in the photo, and
it's rising into the sky.
Jupiter is on the right, it's slowly sinking into the evening sky.
Planets don't twinkle, but maintain steady reflected sunlight, as does the moon.

There will be a test.
