Astronomy tells us of the wonders of the Solar System—the eternally revolving planets, the ra­pidity and certainty of their motions, the distance from planet to planet, from star to star. It pre­dicts with astonishing and marvellous precision the phenomena of eclipses, the visibility upon our Earth of comets, and proves the immutable law of gravitation, but is entirely silent on the exist­ence of a God.

As ages passed, people learned from their ancestors. The more accurately you knew the position and movements of the Sun and Moon and stars, the more reliably you could predict when to hunt, when to sow and reap, when to gather the tribes. As precision of measurement improved, records had to be kept, so astronomy encouraged observation and mathematics and the development of writing.

Astronomy is perhaps the science whose discoveries owe least to chance, in which human understanding appears in its whole magnitude, and through which man can best learn how small he is.

It is remarkable how much of the utilised information men possess has been derived from the observations of astronomers. The mechanism of the universe was known before Harvey discovered the circulation of the blood, or Watt constructed a steam engine. The astronomers seem to have been the pioneers of every branch of human knowledge. The Old and the New Testament open astronomically: "In the beginning God created the heaven and the earth" (Gen., i., I). "The wise men from the east came to Jerusalem, saying, where is He that is born King of Jews? for we have seen His star in the east" (Matt., ii., 2). It must be remembered that the science of astronomy in one important respect differs from all other sciences. Astronomers are observers only - they ascertain causes by watching effects. They cannot interfere with or alter the causes in operation.

It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another and to preserve and cherish the pale blue dot, the only home we've ever known.

Then science came along and taught us that we are not the measure of all things, that there are wonders unimagined, that the Universe is not obliged to conform to what we consider comfortable or plausible. We have learned something about the idiosyncratic nature of our common sense. Science has carried human self-consciousness to a higher level. This is surely a rite of passage, a step towards maturity.

We have now a science called astronomy. That science has done more to enlarge the horizon of human thought than all things else. We now live in an infinite universe. We know that the sun is a million times larger than our earth, and we know that there are other great luminaries millions of times larger than our sun. We know that there are planets so far away that light, traveling at the rate of one hundred and eighty- five thousand miles a second, requires fifteen thousand years to reach this grain of sand, this tear, we call the earth -- and we now know that all the fields of space are sown thick with constellations. If that statute had been enforced, that science would not now be the property of the human mind. That science is contrary to the Bible, and for asserting the truth you become a criminal. For what sum of money, for what amount of wealth, would the world have the science of astronomy expunged from the brain of man? We learned the story of the stars in spite of that statute.

Even the heavens are open to the mind of Man. Man alone of all the animals has traced the pathways of the rising and the setting of the stars. Man has measured out the days and months and years. Man alone has understood and can predict the eclipses of the sun and moon for all future time, when they will occur, and whether they will be partial or total. When the mind contemplates these phenomena, it learns also knowledge of the gods. So religion is born, and with it goodness and all the virtues which make up the good life, a life which reflects the divine life. We need to be inferior to the gods in nothing except our mortality, which need in no way hinder us from living well. In explaining these things, I think that I have shown clearly enough how much superior is human nature to that of all the other animals. From which we must infer that such a shape and arrangement of our limbs and such a power of intelligence cannot have been the work of chance alone.

THE WISDOM OF THE SPHERES

How instructive
is a star!
It can teach us
from afar
just how small
each other are.

It is not simply that a clear understanding is acquired of the movements of the great bodies which we regard as the system of the world, but it is that we are introduced to a perception of laws governing the motion of all matter, from the finest particle of dust to the largest planet or sun, with a degree of uniformity and constancy, which otherwise we could hardly have conceived. Astronomy is pre-eminently the science of order.

neither we nor our planet enjoys a privileged position in Nature. This insight has since been applied upward to the stars, and sideways to many subsets of the human family, with great success and invariable opposition. It has been responsible for major advances in astronomy, physics, biology, anthropology, economics and politics. I wonder if its social extrapolation is a major reason for attempts at its suppression.

The real thing that physics tell us about the universe is that it's big, rare event happens all the time — including life — and that doesn't mean it's special.

I am often asked why I study astronomy and how useful it is in our daily lives. The reality is that astronomy is a long-term investment, and although its benefits might not always be evident it has significant impact in many ways.

Astrology provides a brilliant proof of the miserable subjectivity of human beings, as a result of which they relate everything to themselves and go from every thought in a straight line immediately back to themselves. It relates the course of the great celestial bodies to the pathetic I, as it also connects the comets in the sky with earthly quarrels and shabby tricks.
