Explanation:
What is the band of light connecting the ground to the Milky Way?
Zodiacal light --
a stream of dust that orbits the
Sun in the
inner
Solar System.
It is most easily seen just before sunrise, where it has been called a
false dawn, or just after sunset.
The origin of zodiacal dust remains a
topic of research, but is hypothesized to result from
asteroid collisions and
comet
tails.
The featured wide-angle image shows the central band of our
Milky Way Galaxy
arching across the top, while the
Large Magellanic Cloud
(LMC), a
satellite galaxy to our Milky Way, is visible on the far left.
The image is a combination of
over 30 exposures taken last July near
La Serena
among the mountains of
Chile.
During the next two months,
zodiacal light can appear quite prominent in northern skies just after sunset.
