Explanation: Now

the brilliant “star”
in planet Earth’s evening skies,

Venus is captured in this

creative astrophotograph. Taken with a close-focusing lens on January 18 from

Milton Keynes, UK, it shows multiple images of the sky above the western

horizon shortly after sunset. The images were created by water drops on a glass pane fixed to a tree. Surface

tension
has drawn the water drops into

simple lens-like shapes. Refracting

light, the drops create images that are upside-down,

so the scene has been rotated to allow comfortable right-side up

viewing of a

macro-multiple-skyscape.
