Stars, signs and a path across the Sun

Is there any truth to astrology? For the last time this decade, Mercury has passed in front of the Sun. It has special significance for a growing number of star-gazing, millennial mystics.

The pictures are among the most amazing portraits of space captured by humanity: Mercury, the smallest and fastest-moving planet in our solar system, is a black pin-prick set against a vast, swirling wall of fire.

On Monday, Mercury passed in front of the Sun for the last time this decade, in a rare event called a transit. We will not witness a Mercury transit again until 2032.

It was not just NASA scientists whose eyes were glued to that small, black dot, but also a growing number of millennials who believe that the planets and stars can reveal the future.

Even more excitingly for astrologers, the transit happened while Mercury was in retrograde, when the planet appears to move “backwards” across the sky from west to east. It is one of the most feared times of the astrological calendar, as it is thought to be a time when tensions rise, secrets are buried and disruption reigns.

Is there any truth in astrology?

Signs and stars

To many, astrology is utter nonsense: a hangover from centuries of silly superstition, before the Enlightenment taught us better. Horoscopes are vague enough that anyone can see themselves in them. It doesn’t even make sense on its own terms: the Earth has moved on its axis since the zodiac was first devised, so the signs don’t even correspond to their constellations anymore.

But there’s much more to astrology than simple newspaper horoscopes. True astrology is an art, with the precise location and minute of your birth informing a complex chart of stars, planets and houses. Perhaps those demanding that it be proven to be true are missing the point: astrology provides a rare opportunity for introspection in a noisy world, and puts us in communication with ancestors who used the stars as their calendars, compasses and mirrors.
