    Although hard to believe at first glance, this picture was taken at night.  The image is illuminated by the rising moon behind the camera.  This picture was taken in Queensland, Australia.  Queensland is in the North East of Australia and its capital is Brisbane.  Specifically, this waterfall is Wallaman Falls and has a 268 meter drop.  It is the highest waterfall in Australia.
    The moonbow visible was produced by light reflecting off of the surface of the moon.  They always appear opposite the moon in the sky and are fairly faint.  Sometimes, because they are so faint, moonbows appear white to the naked eye.  Long exposure photography helps to enhance the appearance of color in moonbows.  
   Also, in the center of this photo there is a line which was created by an airplane.  Above and to the right of that, the long almost vertical streak was created by a meteor.  This image is taken with the camera directed toward the center of the Milky Way Galaxy.  The cloudy region in the sky in this photo is the Milky Way Galaxy.
