The Old Moon in the New Moon's Arms

Also known as the Moon's "ashen glow" or
"the old Moon in the new Moon's arms",
Earthshine is
Earthlight reflected from the Moon's night side.
This dramatic image
of Earthshine and a young crescent
Moon was taken by
astrophotographer and
APOD translator
Laurent Laveder from the remote
Pic du
Midi Observatory on planet Earth.
But the
view
from the Moon would have been stunning too.
When the Moon appears in Earth's sky as a slender crescent,
a dazzlingly bright, nearly full Earth would be seen
from the lunar surface.
The Earth's brightness, due to reflected sunlight,
is strongly influenced by cloud cover and
recent studies
of Earthshine indicate that it is more pronounced
during April and May.
A description of Earthshine, in
terms of sunlight reflected by Earth's oceans in turn illuminating
the Moon's dark surface, was written 500 years ago by
Leonardo
da Vinci.
