Cosmigraphics: Picturing Space Through Time in 4,000 Years of Mapping the Universe

By:

A visual catalog of our quintessential quest to understand the cosmos and our place in it.

Long before Galileo invented the telescope, antagonizing the church and unleashing a “hummingbird effect” of innovation, humanity had been busy cataloging the heavens through millennia of imaginative speculative maps of the cosmos. We have always sought to make visible the invisible forces we long to understand, the mercy and miracle of existence, and nothing beckons to us with more intense allure than the majesty and mystery of the universe.

Four millennia of that mesmerism-made-visible is what journalist, photographer, and astrovisualization scholar Michael Benson explores with great dedication and discernment in Cosmigraphics: Picturing Space Through Time (public library) — a pictorial catalog of our quest to order the cosmos and grasp our place in it, a sensemaking process defined by what Benson aptly calls our “gradually dawning, forever incomplete situational awareness.” From glorious paintings of the creation myth predating William Blake’s work by centuries to the pioneering galaxy drawing that inspired Van Gogh’s Starry Night to NASA’s maps of the Apollo 11 landing site, the images remind us that the cosmos — like Whitman, like ourselves — is vast and contains multitudes. This masterwork of scholarship also attests, ever so gently, ever so powerfully, to the value of the “ungoogleable” — a considerable portion of Benson’s bewitching images comes from the vaults of the world’s great science libraries and archives, bringing to light a wealth of previously unseen treasures.

The book’s title is an allusion to Italo Calvino’s beloved Cosmicomics, a passage from which Benson deploys as the epigraph:

In the universe now there was no longer a container and a thing contained, but only a general thickness of signs, superimposed and coagulated, occupying the whole volume of space; it was constantly being dotted, minutely, a network of lines and scratches and reliefs and engravings; the universe was scrawled over on all sides, along all its dimensions. There was no longer any way to establish a point of reference; the Galaxy went on turning but I could no longer count the revolutions, any point could be the point of departure, any sign heaped up with the others could be mine, but discovering it would have served no purpose, because it was clear that, independent of signs, space didn’t exist and perhaps had never existed.

Long before the notion of vacuum existed in cosmology, English physician and cosmologist Robert Fludd captured the concept of non-space in his 1617 creation series, which depicts multiple chaotic fires subsiding until a central starlike structure becomes visible amid concentric rings of smoke and debris. Even though Fludd believed in a geocentric cosmology, this image comes strikingly close to current theories of solar system formation.

Paintings of Saturn by German astronomer-artist Maria Clara Eimmart, a pioneering woman in science, from 1693–1698. Eimmart's depictions are based on a 1659 engraving by Dutch astronomer Christiaan Huygens, the first to confirm that Saturn’s mysterious appendages, which had confounded astronomers since Galileo, were in fact 'a thin flat ring, nowhere touching.' What makes Eimmart's painting unique is that it combines the observations of more than ten astronomers into a depiction of superior accuracy.

In 1845, Anglo-Irish astronomer William Parsons, the 3rd Earl of Rosse, equipped his castle with a giant six-ton telescope, soon nicknamed the 'Leviathan,' which remained the largest telescope in the world until 1918. Despite the cloudy Irish skies, Lord Rosse managed to glimpse and draw the spellbinding spiral structures of what were thought to be nebulae within the Milky Way. This print, based on Lord Rosse’s drawing of one such nebula — M51, known today as the Whirlpool Galaxy — became a sensation throughout Europe and inspired Van Gogh's iconic 'The Starry Night.'

The project, which does for space what Cartographies of Time did for the invisible dimension, also celebrates the natural marriage of art and science. These early astronomers were often spectacular draughtsmen as well — take, for instance, Johannes Hevelius and his groundbreaking catalog of stars. As Benson points out, art and science were “essentially fused” until about the 17th century and many of the creators of the images in the book were also well-versed in optics, anatomy, and the natural sciences.

De Holanda was fascinated by the geometry of the cosmos, particularly the triangular form and its interplay with the circle.

This cryptic and unsettling 'Fool’s Cap Map of the World' (1580–1590), made by an unknown artist, appropriates French mathematician and cartographer Oronce Finé’s cordiform, or heart-shaped, projection of the Earth; the world in this iconic image is dressed in a jester’s belled cap, beneath which a Latin inscription from Ecclesiastes reads: 'The number of fools is infinite.'

The book is, above all, a kind of conceptual fossil record of how our understanding of the universe evolved, visualizing through breathtaking art the “fits and starts of ignorance” by which science progresses — many of the astronomers behind these enchanting images weren’t “scientists” in the modern sense but instead dabbled in alchemy, astrology, and various rites driven by religion and superstition. (For instance, Isaac Newton, often celebrated as the greatest scientist of all time, spent a considerable amount of his youth self-flagellating over his sins, and trying to discover “The Philosopher’s Stone,” a mythic substance believed to transmute ordinary metals into gold. And one of the gorgeous images in Benson’s catalog comes from a 1907 children’s astronomy book I happen to own, titled The Book of Stars for Young People, the final pages of which have always struck me with their counterblast: “Far out in space lies this island of a system, and beyond the gulfs of space are other suns, with other systems: some may be akin to ours and some quite different… The whole implies design, creation, and the working of a mighty intelligence; and yet there are small, weak creatures here on this little globe who refuse to believe in God.”)

Beginning in 1870, French-born artist and astronomer Étienne Trouvelot spent a decade producing a series of spectacular illustrations of celestial bodies and cosmic phenomena. In 1872, he joined the Harvard College Observatory and began using its powerful telescopes in perfecting his drawings. His pastel illustrations, including this chromolithograph of Mare Humorum, a vast impact basin on the southwest side of the Earth-facing hemisphere of the moon, were among the first serious attempts to enlist art in popularizing the results of observations using technology developed for scientific research.

Étienne Trouvelot's 1873 engravings of solar phenomena, produced during his first year at the Harvard College Observatory for the institution's journal. The legend at the bottom reveals that the distance between the two prominences in the lower part of the engraving is one hundred thousand miles, more than 12 times the diameter of Earth. Despite the journal's modest circulation, such engravings were soon co-opted by more mainstream publications and became trailblazing tools of science communication that greatly influenced public understanding of the universe's scale.

What makes Benson’s project especially enchanting is the strange duality it straddles: On the one hand, the longing to make tangible and visible the complex forces that rule our existence is a deeply human one; on the other, the notion of simplifying such expansive complexities into static images seems paradoxical to a dangerous degree — something best captured by pioneering astronomer Maria Mitchell when she marveled: “The world of learning is so broad, and the human soul is so limited in power! We reach forth and strain every nerve, but we seize only a bit of the curtain that hides the infinite from us.”

Unable to seize the infinite, are we fooling ourselves by trying to reduce it into a seizable visual representation? At what point do we, like Calvino’s protagonist, begin to mistake the presence or absence of “signs” for the presence or absence of space itself? It calls to mind Susan Sontag’s concern about how photography’s “aesthetic consumerism” endangers the real experience of life, which the great physicist Werner Heisenberg channeled decades earlier in a remark that exposes the dark side of visualizing the universe:

Contemporary thought is endangered by the picture of nature drawn by science. This danger lies in the fact that the picture is now regarded as an exhaustive account of nature itself so that science forgets that in its study of nature it is studying its own picture.

And yet awe, the only appropriate response to the cosmos, is a visceral feeling by nature and thus has no choice but to engage our “aesthetic consumerism” — which is why the yearning at the heart of Benson’s project is a profoundly human one. He turns to the words of the pioneering English astronomer and mathematician Thomas Wright, whose 1750 book An Original Theory or New Hypothesis of the Universe Benson considers “one of the best-case studies of scientific reasoning through image.” Wright marvels:

What inconceivable vastness and magnificence of power does such a frame unfold! Suns crowding upon Suns, to our weak sense, indefinitely distant from each other; and myriads of myriads of mansions, like our own, peopling infinity, all subject to the same Creator’s will; a universe of worlds, all decked with mountains, lakes, and seas, herbs, animals, and rivers, rocks, caves, and trees… Now, thanks to the sciences, the scene begins to open to us on all sides, and truths scarce to have been dreamt of before persons of observation had proved them possible, invade our senses with a subject too deep for the human understanding, and where our very reason is lost in infinite wonders.

Cosmigraphics is a treasure trove in its entirety. Complement it with a tour of parallel facets of humanity’s visual imagination, Umberto Eco’s atlas of legendary lands and Manuel Lima’s visual history of tree-like diagrams, then revisit the little-known story of how Galileo influenced Shakespeare and this lovely children’s book about space exploration.

Werner Herzog on America and His Lifelong NASA Dream

By:

“The country has always had a capacity to rejuvenate itself, pull itself out of defeat and look to the future. There has always been space there to create real change.”

“America,” young Italo Calvino wrote upon his first visit to the United States, “is the land of the richness of life, of the fullness of every hour in the day, the country which gives you the sense of carrying out a huge amount of activity, even though in fact you achieve very little, the country where solitude is impossible.” But for a land this vast, full of this many people of such enormous diversity, what is “America,” really, if not an abstraction onto which each person projects his or her narrow slice of experience? The landmarks, icons, and stereotypes that have come to signify “America” as a kind of shorthand certainly don’t even begin to capture the full dimension of that abstraction, for the measure of any country — as that of any person — lives between the lines of such shorthand, in the richness of the ordinary and the of the aliveness of the mundane.

From Werner Herzog: A Guide for the Perplexed (public library) — the same wide-ranging interview by Paul Cronin, three decades in the making, that gave us the legendary filmmaker’s no-bullshit advice to aspiring creators and his thoughts on creativity, self-reliance, and how to make a living doing what you love — comes Herzog’s meditation on America. Remarking that contrary to some critical interpretations, his film Stroszek was not intended as a critique of capitalism — “The film doesn’t criticize the country; it’s almost a eulogy to the place,” he adds — Herzog tells Cronin:

What I love is the heartland of the country, the so-called “flyover” zone, like Wisconsin, where we filmed Stroszek and where Orson Welles was from. Marlon Brando came from Nebraska, Bob Dylan from Minnesota, Hemingway from Illinois, these middle-of-nowhere places, to say nothing of the South, the home of Faulkner and Flannery O’Connor. I like this kind of terrain, where you can still encounter great self-reliance and camaraderie, the warm, open hearts, the down-to-earth people. So much of the rest of the country has abandoned these basic virtues. I like America for its spirit of advancement and exploration; there is something exceptionally bold about the place. The idea of everyone having an equal chance to succeed, no matter who they are, is impressive. If a barefoot Indian from the Andes had invented the wheel, the patent office in Washington would have assisted him in securing his rights.

As an immigrant myself, having brushed with the less generous sides of American law during my decade-long tussle with the immigration system, I found Herzog’s optimistic take on the attitudes embedded in other aspects of the law particularly heartening:

When I made The Wild Blue Yonder I discovered an extraordinary cache of footage shot by NASA astronauts in outer space, and was told that because it was filmed by federal employees, the material was “property of the people.” I asked, “Can I, a Bavarian, be considered one of the people?” Such images, it turns out, according to American law belong to everyone on the planet. This is a unique and astounding attitude to the world. Naturally there are things in the United States I’m ambivalent about, just as there are when it comes to Germany. I could never be a flag-waving patriot. But there are many reasons why I have been in America for so many years. The country has always had a capacity to rejuvenate itself, pull itself out of defeat and look to the future. There has always been space there to create real change. I could never live in a country I didn’t love.

Recontextualized NASA footage used in Herzog's The Wild Blue Yonder

Herzog, indeed, holds a soft spot for NASA. “We thank NASA for its sense of poetry,” he says at the end of The Wild Blue Yonder, a line that reads like a eulogy itself as we bear witness to NASA’s tragic downward slide in government priorities today. In contemplating the necessary risks of the creative life, Herzog shares with Cronin his dream of joining NASA — a notion that seems so naturally resonant with his penchant for the lyricism of wanderlust:

I would never complain about how difficult it is to get images that belong to the recesses of the human heart, that show unexpected things we have never seen or experienced before, that are clear, pure and transparent. I would go absolutely anywhere; that’s my nature. Down here on Earth it’s hardly possible any more. I wouldn’t hesitate for a second if given the chance to venture out with a camera to another planet in our solar system, even if it were a one-way ticket. It’s frustrating to me that astronauts never take advantage of the photographic possibilities available to them. On one of the Apollo missions they left a camera on the moon, slowly panning from left to right, then right to left, for days. I yearned to grab the damned thing. There are so many possibilities up there for fresh images, and I always thought it would be better to send up a poet instead of an astronaut; I would be the first to volunteer. I did actually once seriously consider applying to NASA to be on one of their missions. Space travel is unfinished business for me, though these days I wouldn’t be allowed. You need a complete set of teeth to get inside a spaceship.

Werner Herzog: A Guide for the Perplexed is a magnificent read in its hefty totality. Sample Herzog’s life-tested wisdom further here and here, then complement this particular bit with Debbie Millman’s illustrated literary geography of America.

The Edge of the Sky: An Unusual and Poetic Primer on the Universe Written in the 1,000 Most Common Words in the English Language

By:

“Perhaps the All-There-Is is not all there is.”

“If one cannot state a matter clearly enough so that even an intelligent twelve-year-old can understand it,” pioneering anthropologist Margaret Mead wrote in the 1979 volume Some Personal Views, “one should remain within the cloistered walls of the university and laboratory until one gets a better grasp of one’s subject matter.” Whether or not theoretical cosmologist Roberto Trotta read Mead, he embodies her unambiguous ethos with heartening elegance in The Edge of the Sky: All You Need to Know About the All-There-Is (public library) — an unusual “short story about what we think the All-There-Is is made of, and how it got to be the way it is,” told in the one thousand most common words in the English language. Under such admirable self-imposed restriction — the idea for which was given to Trotta by Randall Munroe, who knows a thing or two about illuminating complexity through simplicity — Trotta composes a poetic primer on the universe by replacing some of the densest terminology of astrophysics with invariably lyrical synonyms constructed from these common English words. The universe becomes the “All-There-Is,” Earth our “Home World,” the planets “Crazy Stars,” our galaxy a “Star-Crowd” — because, really, whoever needs supersymmetric particles when one could simply say “Mirror Drops”?

What emerges is a narrative that explains some of the most complex science in modern astrophysics, told in language that sounds like a translation of ancient storytelling, like the folkloric fables of African mythology, the kinds of tales written before we had the words for phenomena, before we had the understanding that demanded those words. Language, after all, always evolves as a mashup of our most commonly held ideas.

Trotta’s story, which spans from the Big Bang (“Big Flash”) to the invention of the telescope (“Big-Seer”) to the discoveries and unknowns that play out at the Large Hadron Collider (“Big Ring”), also features a thoughtfully equalizing play of gender pronouns, casting both women and men as “student-people” — the protagonist-scientists in the history of cosmology and astrophysics.

The story is peppered with appropriately lyrical illustrations by French artist Antoine Déprez.

DARK MATTER: 'In the time it takes you to blink, the number of dark matter drops that fly through your hand is two times the number of people living today in the city that never sleeps.'

In a particularly poetic chapter on space-time and the quest to grasp the scale of the universe, Trotta, who works at the astrophysics group of Imperial College London and has held research positions at Oxford and the University of Geneva, chronicles Einstein’s most enduring legacy:

Doctor Einstein was to become one of the most important student-people ever. He had a quick brain and he had been thinking carefully about the building blocks of the All-There-Is. To his surprise, he found that light was the key to understanding how far-away things in the sky — Crazy Stars, our Star-Crowd, and perhaps even the White Shadows — appear to us.

[...]

You could not explain this using the normal idea of space and time. Mr. Einstein then said that space and time had to be married and form a new thing that he called space-time. Thanks to space-time, he found that time slows down if you fly almost as fast as light and that your arm appears shorter in the direction you are going.

He then asked himself what would happen if you put some heavy stuff, as heavy as a star, in the middle of space-time. He was the first to understand that matter pulls in space-time and changes the way it looks. In turn, the form of space-time is what moves matter one way or another.

It followed that light from stars and the White Shadows in the sky would also be dragged around by the form of space-time. Understanding space-time meant understanding where exactly and how far away from us things are in the sky.

[...]

Mr. Einstein then began to wonder what would happen if he used his space-time idea for the entire All-There-Is.

LARGE HADRON COLLIDER: 'Near that city, student-people have built a large ring under the ground. It would take you over five hours to walk around that Big Ring.'

But Trotta’s greatest feat is the grace with which he addresses the greatest question of cosmology, the one at the heart of the ancient tension between science and religion — the idea that the universe we have seems like a miraculous accident since, despite an infinity of other possible combinations, it somehow cultivated the exact conditions that make life viable. Science rejects the idea of a grand “Creator” who orchestrated these conditions, and religious traditions are predicated on the terror of admitting to such purely accidental origin — a bind with which humanity still tussles vigorously to this day, yet one Trotta untangles with extraordinary intellectual elegance:

Imagine for a minute the following situation.

You enter a room where you find a table with a large number of small, gray, round pieces on it — of the type that you can use to buy a coffee, or a paper, or to pay for parking. The ones with one head on one side and some other picture on the flip side.

Let’s say that there are four hundred of the gray pieces on the table. And they all show heads.

You would not believe for a second that they were all just thrown on the table and happened to land this way. Although this could happen, it would be a hard thing to accept.

It would be easier to imagine that someone had walked into the room before you and had put them all down like this, heads up, all four hundred of them.

The strange thing about the Dark Push is that it is a bit like the four hundred heads-up gray pieces in the room.

If the Dark Push were only a tiny bit larger than it is, then everything we see around us would be very different.

It is as if changing only one of the heads in the four hundred would make the entire world change.

Change the Dark Push by a little bit, and Star-Crowds could not form; none of the stars we see in the sky would be there; the Sun would not be there; our Home-World would not be there; and life, as we know it, could not be here.

We wouldn’t be here to talk about this in the first place.

So the question is: Who or what put down all four hundred heads exactly this way?

MULTIVERSE THEORY: 'Let’s say that there are four hundred of the gray pieces on the table. And they all show heads.'

Trotta offers an answer through a remarkably succinct explanation of the concept of the multiverse and the notion of parallel universes:

Some student-people came to believe that they could understand this by imagining more rooms. A very large number of rooms.

In each of them, the four hundred gray pieces are all thrown up in the air and flipped. And they land in some way, however they may.

In most of the rooms, some of pieces will land heads, and some won’t.

But if you have enough rooms, in the end you’ll find one room where all of the pieces have landed heads-up. Just like that.

There is no need to imagine anyone setting them up in this way.

It’s only a question of having enough rooms and trying them all.

And so the idea is that perhaps the All-There-Is is not all there is.

Trotta also chronicles the origin of the universe and the mechanics of the Big Bang with elegant simplicity:

The All-There-Is started from a single point, but then grew very, very quickly to become very, very large.

It is almost not possible to picture how fast it grew. Imagine breathing into a colored party ball, so that with every breath the ball becomes ten times bigger than before. If every breath took you an hour, you would have to keep going for over three days to make the ball grow as much as the All-There-Is grew right after the Big Flash. By that time, your party ball would have become much bigger than the White Road, so that one hundred party balls would fill the entire part of the All-There-Is we can see!

We don’t know what made it grow so much, so fast.

THE BIG BANG: 'Nearly every matter drop had a Sister Drop flying around, and when they met, they hugged each other and disappeared in a flash of light.'

He distills what we do know about those first few moments of cosmic import, painting a sensual portrait of the science:

At the beginning, all the matter drops were hot and moved around quickly. Nearly every matter drop had a Sister Drop flying around, and when they met, they hugged each other and disappeared in a flash of light. All the drops would have gone and only light would be left over, if it wasn’t for a strange fact.

Imagine a number of matter drops as large as the number of people who live in the land of Mr. Mao today. Each one of them had a matching Sister Drop, and when they found it, both disappeared.

Except for one.

Everything we see around us today is made of the few matter drops that did not have a Sister Drop and that escaped their death hug. As space continued to grow bigger and bigger, it cooled down. During the next three minutes, when the left-over matter drops met another drop they liked, they kissed each other and stuck together. Most matter drops did not find any other drop to kiss, so they stayed alone. We call them the Single Drops.

Almost all the matter drops that kissed each other ended up as Heavier Drops, made of two pairs of different drops. Very few matter drops stuck together to form even bigger drops than the Heavier Drops.

At the end, there were about ten times as many Single Drops as Heavier Drops. Single Drops and Heavier Drops are the same kind of drops that today make up most of the Sun.

Also, a whole lot of much lighter Very Small Drops were still flying around like crazy.

After three minutes, the All-There-Is had grown too much for matter drops to kiss: they simply could not find each other any more in all that big, empty space! Once matter drops stopped kissing one another, nothing much happened for a long time.

The Edge of the Sky: All You Need to Know About the All-There-Is is one part children’s book for grownups, one part imaginative exercise in economical yet lyrical language, and wholly wonderful. For a counterpoint that might well be written in the one thousand least common words in English but is utterly mind-expanding and at least as delightful, see Alan Lightman’s The Accidental Universe.
