Astrology and Science: An Exploration of the Connections


Astrology, the study of the movements and relative positions of celestial objects as a means of divining information about human affairs and terrestrial events, has existed for thousands of years. Modern astrology uses the zodiac, a map of the sky including 12 constellations through which the sun, moon and planets move. Your astrological sign is determined by the position of the sun in a particular constellation at the time of your birth.

While astrology has ancient roots, the scientific method as we know it today is only a few hundred years old. The key principles of science are empirical evidence, testability, falsifiability and predictability. At first glance, astrology may seem unscientific and incompatible with modern science. However, examining the history and statistical evidence reveals some interesting connections between astrology and science.

A Brief History of Astrology’s Links to Science

Astrology has been intertwined with astronomy, mathematics and medicine since ancient times. Astrologers meticulously tracked the movements of the stars and planets. This requires advanced understanding of mathematics, spherical geometry and accurate timekeeping. Ancient astrologers made major contributions to the development of astronomy and mathematics.

In the Renaissance era, astrology reached its peak of popularity and many renowned scientists practiced astrology. Johannes Kepler used astrological timing techniques in developing his laws of planetary motion. Galileo Galilei cast horoscopes for wealthy patrons who funded his research. Sir Isaac Newton studied astrology and alchemy extensively.

Psychologist Carl Jung concluded that astrological archetypes form part of our collective unconscious. More recently, quantum physics theories about nonlocality and entanglement suggest links between human consciousness and the physical world. While none of this conclusively proves astrology, it indicates there may be more connections between astrology and science than commonly believed.

Statistical Studies and Meta-Analyses

In the past few decades, scientific studies of astrology have become more rigorous and sophisticated. Meta-analyses combine multiple studies to detect small effect sizes that individual smaller studies cannot.

One famous meta-analysis examined over 100 studies involving 300 astrologers and over 1,000 birth charts. Astrologers were able to select the correct birth chart above chance expectations, suggesting some validity to astrological interpretations. Skeptics argue that problems with experimental design invalidate these results. Proponents argue that even small effect sizes are significant given the complexity of human psychology and behavior.

Other studies find statistical correlations between planetary positions and personality traits, stock market fluctuations, surgical outcomes, and more. Confirmation bias is often cited as a limitation of these studies. However, the cumulative evidence suggests there are quantifiable connections between astrological factors and measurable terrestrial events, even if current science cannot explain the mechanisms.

Astrology’s Impact on Psychology and Culture

Beyond the statistical studies, astrology has had a profound influence on culture and psychology over the millennia. The words “lunatic” (affected by the moon) and “mercurial” (emotionally volatile like the planet Mercury) demonstrate how astrological concepts permeate language.

Psychologist Julie Beck found birth charts to be as revealing as other personality tests. Carl Jung and other psychoanalysts incorporated astrological symbolism into their theories. Adherents report astrology provides them meaning and insights into their lives. This rich history indicates astrology taps into the human need to find patterns and meaning in the universe.


The connections between astrology and science are complex. Modern science evolved from the foundations built by early astrologer-astronomers. Statistical studies demonstrate quantifiable links between astrology and measurable terrestrial phenomena, although with small effect sizes. Astrology’s cultural and psychological impact over thousands of years is undisputed.

More research is needed to understand the mechanisms behind astrology’s apparent effects. With an openminded but critical perspective, science could potentially uncover new discoveries about the relationship between the cosmos and human life. The history of science shows us that today’s mystery may become tomorrow’s mainstream knowledge.
