|Lunar Eclipse through elusive Gegenschein light from Namibia [Petr Horálek/NASA/APOD].|
: Is there anything interesting to see in the direction opposite
the Sun? One night last month, there were quite a few things. First, the red-glowing orb on the lower right of the original image
is the full moon, darkened and reddened because it has entered Earth's shadow. Beyond Earth's cone of darkness
are backscattering dust particles orbiting the Sun that standout with a diffuse glow called the gegenschein
, visible as a faint band
rising from the central horizon and passing behind the Moon. A nearly horizontal stripe of green airglow
is also discernable
just above the horizon, partly blocked by blowing orange sand.
Visible in the distant sky as the blue dot near the top of the image is the star Sirius
, while the central band of our Milky Way
galaxy arches up on the image left and down again on the right.
