zodiac c<strong>on</strong>stellati<strong>on</strong>s, hence its name. Its subtle radiance is most noticeable around the<br />

spring <strong>and</strong> fall equinoxes.<br />

Known <strong>and</strong> sometimes feared since ancient times, zodiacal light was recorded <strong>by</strong> many<br />

cultures. The Greek philosopher Aristotle c<strong>on</strong>cluded that these misty patches of lights in the<br />

heavens were caused <strong>by</strong> far-off volcanic erupti<strong>on</strong>s. First-century Romans likened them to the<br />

glows of distant unseen fires.<br />

In the 16th century, they were a more ominous associati<strong>on</strong> for the Aztec Empire <strong>and</strong> its ruler,<br />

M<strong>on</strong>tezuma. The king gave up his empire to Cortes <strong>and</strong> his army of Spanish c<strong>on</strong>quistadors in<br />

1519, in part because of the strange appearance of the ghostly pyramid-shaped light that<br />

M<strong>on</strong>tezuma described as a threatening "vast flood of sparkling fire."<br />

The night skies aren't totally dark. At times, sunlight or mo<strong>on</strong>light reflects off high-altitude<br />

clouds, causing a degree of brightness in the starry skies. And dark locati<strong>on</strong>s still offer<br />

glorious views of a b<strong>and</strong> of light running across the overhead sky. This is actually the light<br />

from billi<strong>on</strong>s of stars that make up our own Milky Way galaxy.<br />

But in fact, about 40 per cent of the overall light in the night sky can be attributed to this<br />

zodiacal dust cloud. Sometimes known as the "afterglow of the day," it is often c<strong>on</strong>fused<br />

with twilight, which uniformly encompasses most of the western sky.<br />

Few people today have c<strong>on</strong>sciously observed this astr<strong>on</strong>omical phenomen<strong>on</strong>, mainly because<br />

it is necessary to be well away from city lights to have a chance to see it. At best, zodiacal<br />

light can equal the brightness of the Milky Way, so even the slightest hint of haze in the<br />

atmosphere or light polluti<strong>on</strong> can hide it from view. Despite its faintness, it can take up a<br />

surprisingly big piece of the sky, equivalent to about two fists stacked <strong>on</strong> top of each other,<br />

held at arm's length.<br />

March is the best time of the year to look for the evening zodiacal light. Choose a really<br />

dark site about an hour after sunset <strong>by</strong> escaping the c<strong>on</strong>fines of the city <strong>and</strong> suburbs <strong>and</strong><br />

heading out to the country, particularly <strong>on</strong> a mo<strong>on</strong>less night. Bearing in mind that the display<br />

is named for the zodiac, at this time of the year it will be highlighting the part of the sky<br />

occupied <strong>by</strong> the c<strong>on</strong>stellati<strong>on</strong>s Pisces, Aries <strong>and</strong> Taurus.<br />

Next time you are out <strong>on</strong> a mo<strong>on</strong>less March night, try to glimpse the elusive glow of the<br />

zodiacal light. For those who are less adventurous, just think of the zodiacal light the next<br />

time you dust around the home, <strong>and</strong> thank your lucky stars you d<strong>on</strong>'t have to clean the solar<br />

system - it's full of dust!<br />

GRAPHIC: Color Photo: DOMINIC CANTIN, FREELANCE; A faint c<strong>on</strong>e-shaped glow of<br />

zodiacal light lights the western evening sky in March. Dominic Cantin, an amateur<br />

astr<strong>on</strong>omer from Quebec City, took the photo above with a 35-mm camera <strong>and</strong> wide-angle<br />

lens. For a three-minute exposure, Cantin used a motor (hence the angled horiz<strong>on</strong>) to<br />

compensate for the Earth's rotati<strong>on</strong>.<br />
