If you have access to a very dark observing site during the middle two weeks of March, you have a chance this month to observe the Zodiacal Light, a ghostly cone of illumination centered on the ecliptic caused by the reflection of the Sun’s light from millions of tiny particles in the plane of the planets’ orbits. It is visible just after the end of astronomical twilight, a vast faint triangular glow rising from Venus upward into the constellation of Aries. Be sure your eyes are fully dark adapted in order to see this rare sight.
