Newsday uses an oft erroneously used term, "dark" side of the moon ["Rare sight: Moon's dark side," News, Aug. 7].

The proper term would be "far" side. We on Earth only see one side of the moon as we travel together through space. But the entire surface of the moon is eventually illuminated during each month, depending on its position in relation to the sun.

To quote a well-known line from a Pink Floyd song, "There is no dark side in the moon, really."
