I remember my father had a sermon he used to preach when we were in Florida, in which he gave a reference to the Southern Cross-about the stars, the colors, in the Southern Cross, which thrilled me very much. I must have been around 5 years old. ... Now, it turns out that the Southern Cross itself does have one red star, together with three blue ones.

In a certain sense I made a living for five or six years out of that one star [? Sagittarii] and it is still a fascinating, not understood, star. It's the first star in which you could clearly demonstrate an enormous difference in chemical composition from the sun. It had almost no hydrogen. It was made largely of helium, and had much too much nitrogen and neon. It's still a mystery in many ways ... But it was the first star ever analysed that had a different composition, and I started that area of spectroscopy in the late thirties.

Human beings of all societies in all periods of history believe that their ideas on the nature of the real world are the most secure, and that their ideas on religion, ethics and justice are the most enlightened. Like us, they think that final knowledge is at last within reach. Like us, they pity the people in earlier ages for not knowing the true facts. Unfailingly, human beings pity their ancestors for being so ignorant and forget that their descendants will pity them for the same reason.

At the age of three I began to look around my grandfather's library. My first knowledge of astronomy came from reading and looking at pictures at that time. By the time I was six I remember him buying books for me. ... I think I was eight, he bought me a three-inch telescope on a brass mounting. ... So, as far back as I can remember, I had an early interest in science in general, astronomy in particular.

Sometimes, I think people just want a distraction. It's something you can get excited about that doesn't have to do with politics. It makes you think there's something larger than ourselves - and that can be very powerful.

I still hear some people say that science takes the wonder out of life. Those people are utterly wrong. Science takes us to the wonder

The rules of scientific investigation always require us, when we enter the domains of conjecture, to adopt that hypothesis by which the greatest number of known facts and phenomena may be reconciled.

The best idea ever thought of in the history of humanity is useless unless someone communicates it. It will die in the test tube. And in our case, what we're communicating here to people is not necessarily something they want to hear. And so, our demeanor - how we deliver this message - takes on crucial, crucial importance.

It is a custom often practiced by seafaring people to throw a bottle overboard, with a paper, stating the time and place at which it is done. In the absence of other information as to currents, that afforded by these mute little navigators is of great value.

In the old days, people thought that wouldn't be amenable to life. Modern studies with computers have shown that it's okay to be tidally locked. If a planet heats up on one side and not the other, the atmosphere can still circulate, because heat wants to move around.

What has been done is little-scarcely a beginning; yet it is much in comparison with the total blank of a century past. And our knowledge will, we are easily persuaded, appear in turn the merest ignorance to those who come after us. Yet it is not to be despised, since by it we reach up groping to touch the hem of the garment of the Most High.

The fine tuning of the universe provides prima facie evidence of deistic design.

Lightning seems a thought, which instead of being attached to a brain, is attached to an electric current.

Man is a creature adapted for life under circumstances which are very narrowly limited. A few degrees of temperature more or less, a slight variation in the composition of air, the precise suitability of food, makes all the difference between health and sickness; between life and death.

Such pretensions to nicety in experiments of this nature, are truly laughable! They will be telling us some day of the WEIGHT of the MOON, even to drams, scruples and grains-nay, to the very fraction of a grain!-I wish there were infallible experiments to ascertain the quantum of brains each man possesses, and every man's integrity and candour:-This is a desideratum in science which is most of all wanted.

I gloomily came to the ironic conclusion that if you take a highly intelligent person and give them the best possible, elite education, then you will most likely wind up with an academic who is completely impervious to reality.

I would not spend one further moment on the subject of UFOs if I didnt seriously feel that the UFO phenomenon is real and that efforts to investigate and understand it, and eventually to solve it, could have a profound effect -- perhaps even be the springboard to mankinds outlook on the universe.

The solar system is off center and consequently man is too.

A scientist works largely by intuition. Given enough experience, a scientist examining a problem can leap to an intuition as to what the solution 'should look like.' ... Science is ultimately based on insight, not logic.

One important object of this original spectroscopic investigation of the light of the stars and other celestial bodies, namely to discover whether the same chemical elements as those of our earth are present throughout the universe, was most satisfactorily settled in the affirmative. (1909)

The more progress physical sciences make, the more they tend to enter the domain of mathematics, which is a kind of centre to which they all converge. We may even judge the degree of perfection to which a science has arrived by the facility with which it may be submitted to calculation.

Whether statistics be an art or a science... or a scientific art, we concern ourselves little. It is the basis of social and political dynamics, and affords the only secure ground on which the truth or falsehood of the theories and hypotheses of that complicated science can be brought to the test.

How do you convince someone they're not thinking clearly, when they're not thinking clearly? What we're actually saying is no magic, no afterlife, no higher moral authoritative father-figure, no security, and no happy ever after. This is a tough sell.

You can experience the thrill of discovery, the incredible, visceral feeling of doing something no one has ever done before, see things no one has ever seen before, know something no one has ever known before. ... Welcome to science, you're gonna like it here.

However, science isn't just about showing when you're right; it's also about showing when you're wrong.

Why are the heavens not filled with light? Why is the universe plunged into darkness?

It is well to fetter the wings of our fancy and restrain its flights.

I don't think discovery of a new planet has a huge meaning for children now, but what it means is the world they're growing up in is very different from children of previous generations. We had Star Trek, Star Wars and Futurama - and we still do - but for children today, they will grow up in a world where other stars were known.

In a sense Shapley's telling me that space was transparent, which I shouldn't have believed, illustrates a fundamental problem in science, believing what people tell you. Go and find it out for yourself. That same error has persisted in my life and in many other people's. Authorities are not always authorities on everything; they often cling to their own mistakes.

Science is not always what scientists do.

We can't understand the universe in any clear way without the supernatural.

When you're dealing with the universe, ignorance can be deadly.

Could the waters of the Atlantic be drawn off, so as to expose to view this great sea-gash, which separates continents, and extends from the Arctic to the Antarctic, it would present a scene the most rugged, grand, and imposing. The very ribs of the solid earth, with the foundations of the sea, would be brought to light, and we should have presented to us at one view the empty cradle of the ocean.

When one gets reports from scientists, engineers and technicians whose credibility by all common standards is high and whose moral caliber seems to preclude a hoax, one can do no less than hear them out, in all seriousness.

Welcome to science. You’re gonna like it here.

I have been watching and drawing the surface of Mars. It is wonderfully full of detail. There is certainly no question about there being mountains and large greatly elevated plateaus.

Cloud bounded along the earth like a ball

Astrology ... makes vague predictions that can always be adapted after the fact to fit observations, as we'll see. Astrologers don't seek causes at all, for a good reason: There isn't any cause to astrology. If you look for some underlying reason, some connection between the stars and planets and our lives, you won't find any. For astrology to sell, buyers must not seek out the fundamental principles behind it, because if they do they'll see that there is none.

The more I know of astronomy, the more I believe in God.

Lightning is like an elementary spirit, eccentric or rational, clever or silly, passing from one extreme to the other.

Other job markets may lay claim to the title, but astronomy is actually the world's oldest profession.

If a little kid ever asks you just why the sky is blue, you look him or her right in the eye and say, 'It's because of quantum effects involving Rayleigh scattering combined with a lack of violet photon receptors in our retinae.'
