Astronomers have been bewildered by the theory of an expanding universe, but there is no less expansion in the moral infinite of the universe of man. As far as the frontiers of science are pushed back, over the extended arc of these frontiers one will hear the poet's hounds on the chase.

For it is the duty of an astronomer to compose the history of the celestial motions through careful and expert study.

Astronomers can look back in time. We can look at things as they used to be. We have an idea there was a Big Bang explosion 13.7 billion years ago. We have a story of how galaxies and stars were made. It's an amazing story.

"When I heard the learn'd astronomer;

Students of the heavens are separable into astronomers and astrologers as readily as are the minor domestic ruminants into sheep and goats, but the separation of philosophers into sages and cranks seems to be more sensitive to frames of reference.

I looked about me. Luminous points glowed in the darkness. Cigarettes punctuated the humble meditations of worn old clerks. I heard them talking to one another in murmurs and whispers. They talked about illness, money, shabby domestic cares. And suddenly I had a vision of the face of destiny. Old bureaucrat, my comrade, it is not you who are to blame. No one ever helped you to escape. You, like a termite, built your peace by blocking up with cement every chink and cranny through which the light might pierce. You rolled yourself up into a ball in your genteel security, in routine, in the stifling conventions of provincial life, raising a modest rampart against the winds and the tides and the stars. You have chosen not to be perturbed by great problems, having trouble enough to forget your own fate as a man. You are not the dweller upon an errant planet and do not ask yourself questions to which there are no answers. Nobody grasped you by the shoulder while there was still time. Now the clay of which you were shaped has dried and hardened, and naught in you will ever awaken the sleeping musician, the poet, the astronomer that possibly inhabited you in the beginning.

You know there was a time just before I started to study physical science when astronomers thought that systems such as we have here in the solar system required a rare triple collision of stars.

For it is the duty of an astronomer to compose the history of the celestial motions through careful and expert study.
