Examples of gegenschein in a Sentence
From the description given of the zodiacal band and the Gegenschein, it is clear that these objects should be best seen at the highest elevation, especially within the tropics.
Another anomaly is that he never saw the Gegenschein, but describes the band as equally bright in all its parts, except near the horizon.
Barnard reports it as sometimes best seen when the sky is slightly milky, while during the observations already mentioned from the Rothorn the Gegenschein was scarcely, if at all, visible, though the conditions were exceptionally favourable.
The question whether the Gegenschein can be accounted for by the reflection of light from the same matter as the zodiacal band is still unsettled.
