Short Astronomy Quotes

It seems impossible that you could get something from nothing, but the fact that once there was nothing and now there is a universe is evident proof that you can.

...and his analysis proved him to be the first of theoretical astronomers no less than the greatest of 'arithmeticians.

Each star had cost an effort. For each there had been planning, watching and anticipation. Each one recalled to me a place, a time, a season. Each one now has a personality. The stars, in short, had become my stars.

I had travelled from Spain into Morocco and from there south to the Atlas Mountains, at the edge of the Sahara Desert…one night, in a youth hostel that was more like a stable, I woke and walked out into a snowstorm. But it wasn’t the snow I was used to in Minnesota, or anywhere else I had been. Standing bare chest to cool night, wearing flip-flops and shorts, I let a storm of stars swirl around me. I remember no light pollution, heck, I remember no lights. But I remember the light around me-the sense of being lit by starlight- and that I could see the ground to which the stars seemed to be floating down. I saw the sky that night in three dimensions- the sky had depth, some stars seemingly close and some much farther away, the Milky Way so well defined it had what astronomers call “structure”, that sense of its twisting depths. I remember stars from one horizon to another, making a night sky so plush it still seems like a dream. It was a time in my life when I was every day experiencing something new. I felt open to everything, as though I was made of clay, and the world was imprinting on me its breathtaking beauty (and terrible reality.) Standing nearly naked under that Moroccan sky, skin against the air, the dark, the stars, the night pressed its impression, and my lifelong connection was sealed.

the groundbreakers in many sciences were devout believers. Witness the accomplishments of Nicolaus Copernicus (a priest) in astronomy, Blaise Pascal (a lay apologist) in mathematics, Gregor Mendel (a monk) in genetics, Louis Pasteur in biology, Antoine Lavoisier in chemistry, John von Neumann in computer science, and Enrico Fermi and Erwin Schrodinger in physics. That’s a short list, and it includes only Roman Catholics; a long list could continue for pages. A roster that included other believers—Protestants, Jews, and unconventional theists like Albert Einstein, Fred Hoyle, and Paul Davies—could fill a book.

Magnetism is, of course, not the same as gravity, but Kepler’s fundamental innovation here is nothing short of breathtaking: he proposed that quantitative physical laws that apply to the Earth are also the underpinnings of quantitative physical laws that govern the heavens. It was the first nonmystical explanation of motion in the heavens; it made the Earth a province of the Cosmos. “Astronomy,” he said, “is part of physics.” Kepler stood at a cusp in history; the last scientific astrologer was the first astrophysicist. Not given to quiet understatement, Kepler assessed his discoveries in these words: With this symphony of voices man can play through the eternity of time in less than an hour, and can taste in small measure the delight of God, the Supreme Artist … I yield freely to the sacred frenzy … the die is cast, and I am writing the book—to be read either now or by posterity, it matters not. It can wait a century for a reader, as God Himself has waited 6,000 years for a witness.

Mesoamerica would deserve its place in the human pantheon if its inhabitants had only created maize, in terms of harvest weight the world’s most important crop. But the inhabitants of Mexico and northern Central America also developed tomatoes, now basic to Italian cuisine; peppers, essential to Thai and Indian food; all the world’s squashes (except for a few domesticated in the United States); and many of the beans on dinner plates around the world. One writer has estimated that Indians developed three-fifths of the crops now in cultivation, most of them in Mesoamerica. Having secured their food supply, Mesoamerican societies turned to intellectual pursuits. In a millennium or less, a comparatively short time, they invented their own writing, astronomy, and mathematics, including the zero.

We have been spoiled by artists’ renderings into imagining a clarity of resolution that doesn’t exist in actual astronomy. Pluto in Christy’s photograph is faint and fuzzy—a piece of cosmic lint—and its moon is not the romantically backlit, crisply delineated companion orb you would get in a National Geographic painting, but rather just a tiny and extremely indistinct hint of additional fuzziness. Such was the fuzziness, in fact, that it took seven years for anyone to spot the moon again and thus independently confirm its existence.

As William Bernstein describes in ‘A Splendid Exchange’, ‘The Arabs, invigorated by their conquests, experienced a cultural renaissance that extended to many fields; the era’s greatest literature, art, mathematics, and astronomy was not found in Rome, Constantinople, or Paris, but in Damascus, Baghdad and Cordova.

Before the advent of Islam, the Arab peoples constituted a cultural backwater. With the exception of poetry, they contributed virtually nothing to world civilization, unlike their neighbors—the Egyptians, the Sumerians, the Babylonians, the Persians. Islam changed all that. Shortly after its advent, the Arabs excelled in fields from astronomy to medicine to philosophy. The Muslim golden age stretched from Morocco to Persia and spanned many centuries. Likewise,

If you didn’t find some way of stopping it, people would go on asking questions. The teachers were useful there. Bands of them wandered through the mountains, along with the tinkers, portable blacksmiths, miracle medicine men, cloth peddlers, fortune-tellers, and all the other travelers who sold things the people didn’t need every day but occasionally found useful. They went from village to village delivering short lessons on many subjects. They kept apart from the other travelers and were quite mysterious in their ragged robes and strange square hats. They used long words, like corrugated iron. They lived rough lives, surviving on what food they could earn from giving lessons to anyone who would listen. When no one would listen, they lived on baked hedgehog. They went to sleep under the stars, which the math teachers would count, the astronomy teachers would measure, and the literature teachers would name. The geography teachers got lost in the woodsand fell into bear traps. People were usually quite pleased to see them. They taught children enough to shut them up, which was the main thing, after all. But they always had to be driven out of the villages by nightfall in case they stole chickens.

What we can imagine as plausible is a narrow band in the middle of a much broader spectrum of what is actually possible. [O]ur eyes are built to cope with a narrow band of electromagnetic frequencies. [W]e can't see the rays outside the narrow light band, but we can do calculations about them, and we can build instruments to detect them. In the same way, we know that the scales of size and time extend in both directions far outside the realm of what we can visualize. Our minds can't cope with the large distances that astronomy deals in or with the small distances that atomic physics deals in, but we can represent those distances in mathematical symbols. Our minds can't imagine a time span as short as a picosecond, but we can do calculations about picoseconds, and we can build computers that can complete calculations within picoseconds. Our minds can't imagine a timespan as long as a million years, let alone the thousands of millions of years that geologists routinely compute. Just as our eyes can see only that narrow band of electromagnetic frequencies that natural selection equipped our ancestors to see, so our brains are built to cope with narrow bands of sizes and times. Presumably there was no need for our ancestors to cope with sizes and times outside the narrow range of everyday practicality, so our brains never evolved the capacity to imagine them. It is probably significant that our own body size of a few feet is roughly in the middle of the range of sizes we can imagine. And our own lifetime of a few decades is roughly in the middle of the range of times we can imagine.

His ignorance was as remarkable as his knowledge. Of contemporary literature, philosophy and politics he appeared to know next to nothing. Upon my quoting Thomas Carlyle, he inquired in the naivest way who he might be and what he had done. My surprise reached a climax, however, when I found incidentally that he was ignorant of the Copernican Theory and of the composition of the Solar System. That any civilized human being in this nineteenth century should not be aware that the earth travelled round the sun appeared to be to me such an extraordinary fact that I could hardly realize it. “You appear to be astonished,” he said, smiling at my expression of surprise. “Now that I do know it I shall do my best to forget it.” “To forget it!” “You see,” he explained, “I consider that a man’s brain originally is like a little empty attic, and you have to stock it with such furniture as you choose. A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best is jumbled up with a lot of other things so that he has a difficulty in laying his hands upon it. Now the skilful workman is very careful indeed as to what he takes into his brain-attic. He will have nothing but the tools which may help him in doing his work, but of these he has a large assortment, and all in the most perfect order. It is a mistake to think that that little room has elastic walls and can distend to any extent. Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.” “But the Solar System!” I protested. “What the deuce is it to me?” he interrupted impatiently; “you say that we go round the sun. If we went round the moon it would not make a pennyworth of difference to me or to my work.” I was on the point of asking him what that work might be, but something in his manner showed me that the question would be an unwelcome one. I pondered over our short conversation, however, and endeavoured to draw my deductions from it. He said that he would acquire no knowledge which did not bear upon his object. Therefore all the knowledge which he possessed was such as would be useful to him. I enumerated in my own mind all the various points upon which he had shown me that he was exceptionally well-informed. I even took a pencil and jotted them down. I could not help smiling at the document when I had completed it. It ran in this way— SHERLOCK HOLMES—his limits. 1. Knowledge of Literature.—Nil. 2. Philosophy.—Nil. 3. Astronomy.—Nil. 4. Politics.—Feeble. 5. Botany.—Variable. Well up in belladonna, opium, and poisons generally. Knows nothing of practical gardening. 6. Geology.—Practical, but limited. Tells at a glance different soils from each other. After walks has shown me splashes upon his trousers, and told me by their colour and consistence in what part of London he had received them. 7.

Born in 1821, Croll grew up poor, and his formal education lasted only to the age of thirteen. He worked at a variety of jobs—as a carpenter, insurance salesman, keeper of a temperance hotel—before taking a position as a janitor at Anderson’s (now the University of Strathclyde) in Glasgow. By somehow inducing his brother to do much of his work, he was able to pass many quiet evenings in the university library teaching himself physics, mechanics, astronomy, hydrostatics, and the other fashionable sciences of the day, and gradually began to produce a string of papers, with a particular emphasis on the motions of Earth and their effect on climate. Croll was the first to suggest that cyclical changes in the shape of Earth’s orbit, from elliptical (which is to say slightly oval) to nearly circular to elliptical again, might explain the onset and retreat of ice ages. No one had ever thought before to consider an astronomical explanation for variations in Earth’s weather. Thanks almost entirely to Croll’s persuasive theory, people in Britain began to become more responsive to the notion that at some former time parts of the Earth had been in the grip of ice. When his ingenuity and aptitude were recognized, Croll was given a job at the Geological Survey of Scotland and widely honored: he was made a fellow of the Royal Society in London and of the New York Academy of Science and given an honorary degree from the University of St. Andrews, among much else. Unfortunately,

This is an empirical claim: Look closely enough at your own mind in the present moment, and you will discover that the self is an illusion. The problem with a claim of this kind, however, is that one can’t borrow another person’s contemplative tools to test it. To see how the feeling of “I” is a product of thought—indeed, to even appreciate how distracted by thought you tend to be in the first place—you have to build your own contemplative tools. Unfortunately, this leads many people to dismiss the project out of hand: They look inside, notice nothing of interest, and conclude that introspection is a dead end. But just imagine where astronomy would be if, centuries after Galileo, a person were still obliged to build his own telescope before he could even judge whether astronomy was a legitimate field of inquiry. It wouldn’t make the sky any less worthy of investigation, but astronomy’s development as a science would become immensely more difficult. A few pharmacological shortcuts exist—and I discuss some of them in a later chapter—but generally speaking, we must build our own telescopes to judge the empirical claims of contemplatives. Judging their metaphysical claims is another matter; many of them can be dismissed as bad science or bad philosophy after merely thinking about them. But to determine whether certain experiences are possible—and if possible, desirable—and to see how these states of mind relate to the conventional sense of self, we have to be able to use our attention in the requisite ways. Primarily, that means learning to recognize thoughts as thoughts—as transient appearances in consciousness—and to no longer be distracted by them, if only for short periods of time. This may sound simple enough, but actually accomplishing it can take a lot of work. Unfortunately, it is not work that the Western intellectual tradition knows much about. LOST

[W]e can calculate our way into regions of miraculous improbability far greater than we can imagine as plausible. Let's look at this matter of what we think is plausible. What we can imagine as plausible is a narrow band in the middle of a much broader spectrum of what is actually possible. Sometimes it is narrower than what is actually there. There is a good analogy with light. Our eyes are built to cope with a narrow band of electromagnetic frequencies (the ones we call light), somewhere in the middle of the spectrum from long radio waves at one end to short X-rays at the other. We can't see the rays outside the narrow light band, but we can do calculations about them, and we can build instruments to detect them. In the same way, we know that the scales of size and time extend in both directions far outside the realm of what we can visualize. Our minds can't cope with the large distances that astronomy deals in or with the small distances that atomic physics deals in, but we can represent those distances in mathematical symbols. Our minds can't imagine a time span as short as a picosecond, but we can do calculations about picoseconds, and we can build computers that can complete calculations within picoseconds. Our minds can't imagine a timespan as long as a million years, let alone the thousands of millions of years that geologists routinely compute. Just as our eyes can see only that narrow band of electromagnetic frequencies that natural selection equipped our ancestors to see, so our brains are built to cope with narrow bands of sizes and times. Presumably there was no need for our ancestors to cope with sizes and times outside the narrow range of everyday practicality, so our brains never evolved the capacity to imagine them. It is probably significant that our own body size of a few feet is roughly in the middle of the range of sizes we can imagine. And our own lifetime of a few decades is roughly in the middle of the range of times we can imagine.

My biggest fear is not getting done that which must be done before my short life ends.

I have existed only a short time and I can even tell you to live purely for oneself is never enough and never shall be.

Supernovas- a supernova can be caused due to nuclear fusion in degenerate stars or by the ‘gravitational collapse of the core of a massive star’. Supernovas occur for a short amount of time and then fade over a time span of weeks or months.

Within people there is a longing and a desire such that, even if a hundred thousand worlds were theirs to own, still they would find no rest or comfort. They try every trade and craft, studying astronomy, medicine and every other subject, but they reach no completion, for they have not found their true desire. Poets call the Beloved “heart’s ease,” because there the heart finds ease. How can we find peace and rest in anything but the Beloved? All these pleasures and pursuits are like a ladder. The rungs of a ladder are not a place to make one’s home; they are for passing by. Fortunate are those who learn this. The long road becomes short for them, and they do not waste their lives upon the steps.

happiness doesn’t depend on Ron’s goalkeeping ability.” And though Harry would rather have jumped off the Astronomy Tower than admit it to her, by the time he had watched the game the following Saturday he would have given any number of Galleons not to care about Quidditch either. The very best thing you could say about the match was that it was short; the Gryffindor spectators had to endure only twenty-two minutes of agony. It was hard to say what the worst thing was: Harry thought it was a close-run contest between Ron’s fourteenth failed save, Sloper missing the Bludger but hitting Angelina in the mouth with his bat, and Kirke shrieking and falling backward off his broom as Zacharias Smith zoomed at him carrying the Quaffle. The miracle was that Gryffindor only lost by ten points: Ginny managed to snatch the Snitch from right under

DELTA GEMINORUM and PLUTO. The new planet (arrow) is shown here shortly after discovery at Lowell Observatory, in February 1930. Date of Photograph is March 4, 1930.

One nice touch about Christy’s discovery was that it happened in Flagstaff, for it was there in 1930 that Pluto had been found in the first place. That seminal event in astronomy was largely to the credit of the astronomer Perdval Lowell. Lowell, who came from one of the oldest and wealthiest Boston families (the one in the famous ditty about Boston being the home of the bean and the cod, where Lowells spoke only to Cabots, while Cabots spoke only to God), endowed the famous observatory that bears his name, but is most indelibly remembered for his belief that Mars was covered with canals built by industrious Martians for purposes of conveying water from polar regions to the dry but productive lands nearer the equator. Lowell’s other abiding conviction was that there existed, somewhere out beyond Neptune, an undiscovered ninth planet dubbed, Planet X. Lowell based this belief on irregularities he detected in the orbits of Uranus and Neptune, and devoted the last years of his life to trying to find the gassy giant he was certain was out there. Unfortunately, he died suddenly in 1916, at least partly exhausted by his quest and the search fell into abeyance while Lowell’s heirs squabbled over his estate. However, in 1929, partly as a way of deflecting attention away from the Mars canal saga (which by now had become a serious embarrassment), the Lowell Observatory directors decided to resume the search and to that end hired a young man from Kansas named Clyde Tombaugh. Tombaugh had no formal training as an astronomer, but he was diligent and he was astute, and after a year’s patient searching he somehow spotted Pluto, a faint point of light in a glittery firmament. It was a miraculous find, and what made it all the more striking was that the observations on which Lowell had predicted the existence of a planet beyond Neptune proved to be comprehensively erroneous. Tombaugh could see at once that the new planet was nothing like the massive gasball Lowell had postulated, but any reservations he or anyone else had about the character of the new planet were soon swept aside in the delirium that attended almost any big news story in that easily excited age. This was the first American-discovered planet and no one was going to be distracted by the thought that it was really just a distant icy dot. It was named Pluto at least partly because the first two letters made a monogram from Lowell’s initials. Lowell was posthumously hailed everywhere as a genius of the first order, and Tombaugh was largely forgotten, except among planetary astronomers, who tend to revere him.

I don't think she can see her husband very often, for he teaches the university students during the day, and works at the telescope at night. I wonder if she hopes for cloudy nights and then feels guilty.

I’ll be hanged if I can understand how it concerns Evolution to get us out of a mere scrape.” “Out of all kinds of scrapes, my dear Brumm, Evolution has the power to deliver us. There is no conceivable scrape which is not a link in the great chain—in Chance, which is the empirical name for Evolution, and bears the same relation to it that alchemy bears to chemistry, and astrology to astronomy. And the last little scrape of all, death, is simply the charming means Evolution takes to get us out of the great big scrape, life. You will never be happy, my dear friend, until you submit to the Evolutionary will. If it were not so amusing, nothing would be more insufferable than the unanimity and persistency with which all men and kindreds and nations shout up into space, ‘What a scrape were in!’ It is the first thing the child says in its inarticulate way with the first breath of air it is able to employ. ‘Oh, what a scrape to be sure!’ And it is the last thing the man feels on his death-bed. And you will find that all the books and newspapers and music in the world are only expositions and sermons and fugues and variations on the one theme. ‘Oh, what a scrape!’ Now, it is my mission to change the world’s tune. I mean to teach it that scrape, luck, chance, is law, is Evolution, is the soul of the universe; and having brought man’s will into accord with the Evolutionary will, in a very short time it will come about that children will laugh with their first breath, as much as to say, ‘ What a delightful thing it is to come into the world.’ And on their death-beds men will cry, ‘How refreshing and noble it is to pass away,’ while all the books and newspapers and music of the world will cease to be a mere complaint, will cease—altogether, the books and newspapers, perhaps, and only glad music remain.

Space telescopes have smaller mirrors than ground-based telescopes, but they do not suffer the obscuring effect of the atmosphere. For infrared astronomy, this has been transformative. The launch of the Infrared Astronomical Satellite (IRAS) space telescope in 1983 opened up the full sky to full-spectrum infrared astronomy, but it was the Spitzer space telescope, launched in 2003, that in a voyage of discovery lasting nearly two decades really opened the floodgates. Spitzer surveys have mapped 90% of the star-forming regions within 1,600 light years, yielding infrared spectra of over 2,000 young stellar objects. It is because of Spitzer that we know young stars almost invariably are surrounded by dusty disks when they first become visible a mere half million years into their existence. These disks typically extend out to at least 10 au from the star, and exhibit a hot inner disk without any evidence of a hole cleared out near the star.

All truths are against us. But we go on living, because we accept them in themselves, because we refuse to draw the consequences. Where is the man who has translated – in his behaviour – a single conclusion of the lessons of astronomy, of biology, and who has decided never to leave his bed again out of rebellion or humility in the face of the sidereal distances of the natural phenomena? Has pride ever been conquered by the evidence of our unreality? And who was ever bold enough to do nothing because every action is senseless in infinity? The sciences prove our nothingness. But who has grasped their ultimate teaching? Who has become a hero of total sloth? No one folds his arms: we are busier than the ants and the bees...

Shutting down the biologically toxic Mauna Kea Observatories is the short term goal. The long term goal is shutting down the biologically toxic Space industry.

Steven Magee, Chartered Electrical Engineer, was medically diagnosed with Amnestic Disorder which is characterized by short term memory loss in 2016 at the age of 46. He had worked for five years on the 13,796 feet very high altitude summit of Mauna Kea, Hawaii, USA from 2001 to 2006 and had noticed memory problems developing during the last years that he worked there. The condition has now progressed into a disability.

I started showing depression symptoms shortly after my very high altitude coworker stated that they were experiencing gender issues.

The first and better known is Mesoamerica, where half a dozen societies, the Olmec first among them, rose in the centuries before Christ. The second is the Peruvian littoral, home of a much older civilization that has come to light only in the twenty-first century.* Mesoamerica would deserve its place in the human pantheon if its inhabitants had only created maize, in terms of harvest weight the world’s most important crop. But the inhabitants of Mexico and northern Central America also developed tomatoes, now basic to Italian cuisine; peppers, essential to Thai and Indian food; all the world’s squashes (except for a few domesticated in the United States); and many of the beans on dinner plates around the world. One writer has estimated that Indians developed three-fifths of the crops now in cultivation, most of them in Mesoamerica. Having secured their food supply, Mesoamerican societies turned to intellectual pursuits. In a millennium or less, a comparatively short time, they invented their own writing, astronomy, and mathematics, including the zero.

This is what daily working is like at the very high altitude Mauna Kea Observatories (MKO): Get the workers up the mountain as fast as possible with a short stop for breakfast. Tell the workers to take the company supplied drugs to do their jobs and get the sickened workers off the mountain as fast as possible at the end of the work day. The sickened workers spend their evenings feeling really crappy and repeat the cycle again the next day.

In the Solar System, Enceladus ought to be one of the highest priorities for the world's space agencies. Enceladus has a source of energy (tidal heating), organic material, and liquid water. That's a textbook-like list of those properties needed for life. Moreover, nature has provided astrobiologists with the ultimate free lunch: jets that spurt Enceladus's organic material into space.
