The gegenschein appears in this image as a bright spot on the diagonal band (running top left to lower right) above the Very Large Telescope. (The Andromeda Galaxy and Pleiades are prominent in the lower half of the image.)
Gegenschein (/ˈɡeɪɡənˌʃaɪn/; German:[ˈɡeːɡn̩ˌʃaɪn]; lit.'counter-shine') or counterglow is a faintly bright spot in the night sky centered at the antisolar point. The backscatter of sunlight by interplanetary dust causes this optical phenomenon, being a zodiacal light and part of its zodiacal light band.
