John N. Bahcall on Why we Should Do Astronomy
We should do astronomy because it is beautiful and because it is fun. We should do it because people want to know. We want to know our place in the universe and how things happen.

We should do astronomy because it is beautiful and because it is fun. We should do it because people want to know. We want to know our place in the universe and how things happen.
The way we discovered how species arise resembles the way astronomers discovered how stars “evolve” over time. Both processes occur too slowly for us to see them happening over our lifetime. But we can still understand how they work by finding snapshots of the process at different evolutionary stages and putting these…
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to…
The formation of planets is like a gigantic snowball fight. The balls bounce off, break apart, or stick together, but in the end they are rolled up into one enormous ball, a planet-ball that has gathered up all the snowflakes in the surrounding area.
Metaphysically speaking, no one paradigm is innately any better than any other. A universe that began at 9 a.m. on October 10, 4004 B.C. (which was official back in the seventeenth century) is intrinsically no less valuable for those who live by a belief in it than is our present uncertain universe, perhaps built like…
We lay and looked up at the sky and the millions of stars that blazed in darkness. The night was so still that we could hear the buoy on the ledges out beyond the mouth of the bay. Once or twice a word spoken by someone on the far shore was carried across the clear air. A few lights burned in the cottages. Otherwise…
We have become too wise in our own conceits if ever we let a winter solstice go by without a glance upward to rejoice that the sun will sink no lower in the darkening sky . .. We walk too hurriedly if ever we pass the season’s first pasqueflower by, too busy to let its meeting stay us for a quiet moment before this…
After an evening of talk, perhaps about the fringes of knowledge, or some new possibility of climbing inside the minds and senses of animals, we would go out on the lawn, where we took turns at an amusing little astronomical rite. We searched until we found, with or without glasses, the faint, heavenly spot of…
If the Stars should appear one night in a thousand years, how would men believe and adore; and preserve for many generations the remembrance of the city of God which had been shown! But every night come out these envoys of beauty, and light the universe with their admonishing smile.
A more sophisticated consequence of omphalogical reasoning would be that stars whose distance from us is more than a few thousand light years must have been created with ready-made light beams stretching almost all the way to us - otherwise we wouldn't be able to see them until the distant future!
Explosions are seldom one hundred per cent efficient. When a star ends as a supernova, the nuclear explosive material, which includes uranium and plutonium together with large amounts of iron and other burnt-out elements, is distributed around and scattered in space just as is the dust cloud from a hydrogen bomb test…
Once upon a time, we soared into the solar system, for a few years. Then we hurried back. why? What happened? What was Apollo really about? The scope and audacity of John Kennedy's May 25th 1961 message to a joint session of Congress on "Urgent National Needs" -- the speech that launched the Apollo program--dazzled…
First, I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none…
