There is also a very faint, but still slightly increased, oval glow directly opposite the Sun which is known as the gegenschein. |
But the gegenschein is very faint, a few magnitudes fainter than the Milky Way. |
There have been reports that under very favorable viewing conditions the zodiacal light extends to the gegenschein. |
The gegenschein is an extremely elusive phenomenon, suitable only for eyes that have been specially trained to see it. |
Barnard finds that the gegenschein is not so faint as is generally supposed. |
These are known respectively as the Zodiacal Light and the gegenschein. |
