A rare phenomenon, known as Zodiacal Light (a.k.a. False Dusk/Dawn), was captured during my recent trip to Mount Bromo in the Southern Hemisphere. Zodiacal light is best seen during Spring and Autumn and I chose to visit Mt Bromo a few days after Autumnal Equinox as I hope to capture the Zodiacal light along with the 3 planets, 3 volcanoes and a milky way galaxy. If I had visited Mount Bromo during Vernal Equinox, I will not be able to capture this rare phenomenon with the cones of the 3 volcanoes because the Zodiacal light would have appear before dawn, in the East.
This timelapse movie shows how the zodiacal light became visible as the sky was approaching towards its astronomical darkness state. That's why we were able to see the milkyway galaxy and the Zodiacal light also created a false dusk impression. During normal day, you will not be able to see the sunset colors at this time because the sky would have been completely dark! Zodiacal light appears as a faint light in this movie coming from Mount Batok pointing towards the Milky Way Galaxy but it's actually pointing towards the pathway traveled by the Sun and Moon as they journey across our sky. Venus, Saturn and Mercury were visible above the cones of 3 volcanoes namely from left to right, Mount Semeru, Mount Bromo and Mount Batok.
Zodiacal light is actually sunlight reflecting off dust grains that circle the sun in the inner solar system. These grains are thought to be left over from the process that created our Earth and the other planets of our solar system 4.5 billion years ago.
