Zodiacal Light before Dawn
You might not guess it, but sunrise was still hours away when
this nightscape was taken,
a view along the eastern horizon from a remote location in Chile's
Atacama
desert.
Stretching high into the otherwise dark, starry sky
the unusually bright conical glow is sunlight though,
scattered by dust along the solar system's
ecliptic
plane .
Known as
Zodiacal
light, the apparition is also nicknamed the "false dawn".
Near center, bright star Aldebaran and the Pleiades star cluster seem
immersed in the Zodiacal light, with Orion toward the right
edge of the frame.
Reddish emission from NGC 1499, the California Nebula,
can also be seen through the tinge of airglow along the horizon.
