A different astronomy and space science related image is featured each day, along with a brief explanation.
A scenic and hilly landscape is shown just before sunrise. On the left is Comet Nishimura near the horizon with a long tail fading off toward the top of the frame. On the right is a bright spot that is Venus. The sunrise sky is dark blue at the top but morphs into tan at the horizon, while the foreground hills are green.
