Quick Reference

A phenomenon in which the unlit portion of Venus's globe glows faintly when the phase is a thin crescent. It may be caused by refraction of sunlight in Venus's very dense atmosphere or by atmospheric electrical phenomena. The ashen light is fainter than earthshine on the Moon, and can be seen only when Venus is very close to inferior conjunction, but even then it is rare.
