As Earth spins under the sky, stars and planets,and the sun and moon, rise in the east, to begin their sweep across the sky. When an astrophotographer captures their apparent movement, it’s called a star trail, or – in this case of this wonderful shot by Balai Cerap in Malaysia – a planet trail. Balai captured the three morning planets – Jupiter, Mars and Venus – in this composite image created on November 10, 2015.
Thank you, Balai!
