At one glance, one may think that this image is
photoshopped or it’s a composite because it’s simply impossible to see Milky
Way galaxy at dusk. But what you’re really seeing here is a single exposure
shot of a rare phenomenon, known as zodiacal light (a.k.a. “false dusk”), that
I have 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 [the Southern Hemisphere's autumnal equinox]
as I hoped to capture the zodiacal light along with the 3 planets, 3 volcanoes
and a Milky Way galaxy.
This image was captured when the sun was around 15
degrees below the horizon and the sky was reaching its astronomical darkness
state.
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.
A Hubble Space Telescope image shows
unprecedented detail of the Antennae galaxies, an intense star-forming region
created when two galaxies began to collide some 200 million to 300 million
years ago. The bright, blue-white areas show newly formed stars surrounded by
clouds of hydrogen, which are colored pink. A similar collision is expected
between our galaxy, the Milky Way, and the nearby Andromeda galaxy in several
billion years.
Light pollution in urban skies makes it
almost impossible for any aspiring astrophotographers to pursue their craft
here in Singapore. Since I started deep sky astrophotography in August 2013, I
have been asking myself if it’s really impossible to capture the Milky Way galaxy
in Singapore and so, I’ve decided to make my first attempt in February 2014,
with the help of my web-based astronomy tool,
after the monsoon season was over and voila! I could see it! All hope
was not lost after all.
And if a single-exposure image is not
convincing enough, I have also filmed a time-lapse video (before I took the
lonely tree shot,) showing both the Milky Way and planet Venus rising over the
light-polluted skies of Singapore, using just a normal DSLR camera and lens.
