Moon Observer's Guide by Peter GregoPhilip’s Moon Observer’s Guide, Peter Grego (Philip’s 2015)

If you ask someone to name the most important inventions in history, two will often be overlooked: the microscope and the telescope. You could say that one lowered the floor of the universe and the other raised the ceiling: we suddenly became aware of wonders that had previously been too small or too far away for us to see.

Practically speaking, the microscope might seem by far the more important, because it’s taught us so much about life on earth, not least our own. But the continued existence of humanity may actually depend on the telescope. Geologists have discovered that the earth has repeatedly been struck by asteroids; astronomers may be able to spot the next one before it hits. Otherwise we may follow the dinosaurs, trilobites, eurypterids and countless other once-flourishing groups into extinction.

If you want to see what asteroids and other large rocks can do to a celestial body, Mother Nature has kindly provided us with a giant memento mori: the Moon. The biggest scars there are visible with the naked eye, but it took the telescope to reveal quite what they looked like and quite how pock-marked the lunar surface is. As Peter Grego writes:

All the Moon’s ringed basins, ‘walled plains’ and the overwhelming majority of craters visible through the telescope were formed by asteroidal impact. […] Copernicus was blasted out of the lunar crust about 800 million years ago by an asteroid measuring up to 10 km across. The 29 km diameter crater Kepler, 500 km to the west of Copernicus, was formed at around the same time. (“Lunar geology and the Moon’s features”, pp. 13-4)

Grego knows a lot about the Moon and this book is the fruit of more than thirty years of selenoscopy, dating back to his first “systematic observations” in 1982:

Since that time, through patient observing and recording, the lunar landscape has become to me a broadly familiar place, yet always full of wonder. Today only a sliver of moon is visible, and the eastern lunar seas and their surrounding craters provide a visual delight until the Moon sinks into the haze above the city and its image dims, shimmers and degrades. (pg. 5)

The city was Birmingham back in 2002. Cities aren’t just noisy, dirty and harmful to wildlife. They also deprive us of one of the greatest sights in nature: the night sky. Light pollution is silent, tasteless and physically harmless, but it deserves much more attention from conservationists. The Moon can be big enough and bright enough not to be wholly drowned by it, but it’s lèse-majesté against the Queen of the Night all the same.

It also makes life much harder for amateur astronomers. Then again, perhaps that increases the rewards. And the Moon isn’t confined to the night sky, of course: you can observe it in full daylight using nothing more than binoculars. Serious observation demands a telescope, however, and Grego devotes a full section to what’s available. Inter alia, he himself has a “150mm f/8 achromatic refractor with digital camcorder setup with a zoom eyepiece for afocal video photography” (ch. 5, “Recording Your Observations”, pg. 144). Digital imaging and enhancement are now routine: modern technology can get “startling results from a seemingly mediocre video sequence” (pg. 146), sharpening and focusing blurred images.

But Grego and his fellow selenographers are still doing what Galileo, Thomas Harriot and other early astronomers did centuries ago: drawing and sketching the Moon. There’s a good practical reason to do this, as recent science-news has confirmed: “drawing pictures of information that needs to be remembered is a strong and reliable strategy to enhance memory”. There is a lot of detail to learn on the Moon. It’s a fractal place: there are craters at every scale, from the microscopic to hundreds-of-kilometres wide and “it is estimated that the Moon’s surface is studded with more than 3 trillion (3,000,000,000,000) craters larger than a metre in diameter” (pg. 9).

So learning your way around the Moon is a fractal process: first you learn to recognize the giant features, like Copernicus, Kepler and the maria (seas), montes (mountains) and valles (valleys), then you begin to fill in the gaps, then the gaps between the gaps, then the gaps between those. Grego supplies maps and commentary to help you on your way:

The polygonal crater Timaeus (33 km) perches on W. Bond’s south-western wall and surveys across the plains of Mare Frigoris across to the Montes Alpes, 175 km to the south. Archytas (32 km) and Protagoras (21) are two sharp-rimmed but somewhat misshapen craters whose dark shadow-filled eyes keep watch over the northern approaches of Mare Frigoris. (ch. 4, “Moonwatching”, Day seven, pg. 87)

He’s never finished learning about the Moon, however, and neither will anyone else. It’s a life-long adventure and although the Moon might seem cold and unchanging, at least over a human life-span, there are rare events called TLP, or “Transient Lunar Phenomena”, to look out for. These are “apparent obscurations, glows or flashes on the Moon’s surface” that don’t have definitive explanations. Are rocks collapsing? Is sublunar gas leaking out? Might there even be life there after all?

Life is highly doubtful, but Grego notes that “lunar topography is virtually neglected by professional astronomers” (pg. 6), so amateurs still have the chance to make important discoveries. This book might help someone to do that, but the rewards of selenoscopy don’t depend on advancing science or using clever technology. Grego opens the book by asking “Why Observe the Moon?”, then quotes an excellent answer to that question from the French astronomer Camille Flammarion and his book Astronomy for Amateurs (1903). What Flammarion said more than a century ago is still true today:

From all time the Moon has had the privilege of charming the gaze, and attracting the particular attention of mortals. What thoughts have not risen to her pale, yet luminous disk? Orb of mystery and of solitude, brooding over our silent nights, this celestial luminary is at once sad and splendid in her glacial purity, and her limpid rays provoke a reverie full of charm and melancholy. (“Why Observe the Moon?”, pg. 4)

In fact, you could say that the Moon is a touchstone of human nature. Chimpanzees and gorillas may be almost identical to us in their genes, but they don’t talk, make art or gaze at the Moon in wonder. We still do and although we don’t usually worship the Moon any more, we may owe it our very existence. How important have the tides been in the evolution of life on earth? They provided a zone of transition for the emergence of plants and animals from the sea, and perhaps a Moon-less Earth would also be a Man-less Earth.

But the Earth could have Moon without Man if it’s struck by an asteroid of sufficient size. The scars on the Moon’s surface should be constant reminders of the vigilance that’s necessary and the technology that we still need to develop. But the Moon is memento mori in more ways than one. Asteroid strikes are pinpricks by comparison with what may have happened to the Earth in the remote past:

Now widely accepted to be the most likely origin of the Moon is the giant impact or ‘big splash’ theory. This theory suggests that a Mars-sized planet (around half the size of the Earth) smashed into the young Earth, disintegrating the impactor and the Earth’s mantle at the site of impact. A cloud of debris was splashed into near-Earth orbit, and the outer rings of this temporary ring of material coalesced to form the Moon. (ch. 1, pg. 21)

As Sir Arthur Conan Doyle’s great character Professor Challenger pointed out in 1913: there are “many reasons why we should watch with a very close and interested attention every indication of change in those cosmic surroundings upon which our own ultimate fate may depend”. The Moon should frighten as well as awe and enchant us, or we might not survive to be awed and enchanted. This book will help you understand all these aspects of the Queen of the Night.

I also hope that Grego will write a sequel to it one day: Moon Tourist’s Guide. We’re still on schedule for at least some of the future envisaged by Arthur C. Clarke in his novel A Fall of Moondust (1961), which was set in the mid-twenty-first century. A moon-cruiser called Selene may not be sailing in a basin of dust as “fine as talcum-powder” by then, but there may still be lunar tourism. If so, selenographers like Peter Grego will be able to see close-up what they’ve long surveyed from afar.

Front cover of The Lost World by Arthur Conan DoyleThe Lost World and Other Stories, Arthur Conan Doyle (various dates)

Professor Challenger, the “ape-man in a lounge-suit”, is someone else in Sherlock’s shadow, but in some ways he’s much more interesting than Doyle’s detective. Holmes may have set “the whole world talking” but “to set the whole world screaming was the privilege of Challenger alone.” He does that in the last story of the collection, “When the World Screamed” (1928), in which the earth is found to be even more alive than the modern Gaia theory suggests. And it kicks against Challenger’s prick. That foreshadowing of later science is also found in “The Poison Belt” (1913):

A third-rate sun, with its rag tag and bobtail of insignificant satellites, we float towards some unknown end, some squalid catastrophe which will overwhelm us at the ultimate confines of space, where we are swept over an etheric Niagara or dashed upon some unthinkable Labrador. I see… many reasons why we should watch with a very close and interested attention every indication of change in those cosmic surroundings upon which our own ultimate fate may depend.

There are some very interesting and prescient ideas here: Doyle should get much more credit for his pioneering science fiction, but again Holmes is probably to blame. Not that Holmes would have wanted to take the limelight: he’s introverted and not played for comedy. Challenger is the opposite in both ways. Ted Malone, the narrator of “The Lost World” (1912), notes that his “enormously massive genial manner” is “almost as overpowering as his violence”. Later, Malone has an unpleasant encounter with a tick in the South American jungle:

“Filthy vermin!” I cried.

Professor Challenger raised his great eyebrows in protest, and placed a soothing paw upon my shoulder.

“You should cultivate the scientific eye and the detached scientific mind,” said he. “To a man of philosophic temperament like myself the blood-tick, with its lancet-like proboscis and its distending stomach, is as beautiful a work of Nature as the peacock or, for that matter, the aurora borealis. It pains me to hear you speak of it in so unappreciative a fashion. No doubt, with due diligence, we can secure some other specimen.”

“There can be no doubt of that,” said Summerlee, grimly, “for one has just disappeared behind your shirt-collar.”

Challenger sprang into the air bellowing like a bull, and tore frantically at his coat and shirt to get them off.

Each of the four main characters in “The Lost World” has a distinct personality, as though Doyle is trying to embody the Greek humours: there’s the choleric Challenger; the phlegmatic Summerlee, Challenger’s sardonic rival; the sanguine Lord Roxton, a big-game huntsman who accompanies the expedition for sport; and the melancholic Irishman Ted Malone, the journalist who narrates the story. This makes for entertaining reading, as I’ve found every time I’ve come back to the story. And my re-readings must be in double figures now. Doyle’s racial descriptions will provoke disapproval in many modern readers, but they’re something else that may be prescient and they aren’t confined to “villainous half-breeds” and the “huge negro Zambo, who is as faithful as a dog” but not very intelligent. Doyle also describes the Irish as distinct within the white European race, which does seem to be the case.

But Doyle’s prescience has failed so far in the longest story of the collection, which, in its way, is another joke at Professor Challenger’s expense. Having made the character popular before the First World War, Doyle shoe-horned him into “The Land of Mist” in 1927 as part of his propaganda for spiritualism. I’ve never re-read this story, which has more historical and biographical interest than literary merit. Doyle lost a son and brother during the War and the wishful thinking that inspired his support of spiritualism is evident throughout the story. He even makes Challenger turn on his head for the purposes of spiritualist propaganda. This is Challenger in “The Poison Belt” in 1913:

“No, Summerlee, I will have none of your materialism, for I, at least, am too great a thing to end in mere physical constituents, a packet of salts and three bucketfuls of water. Here ― here” ― and he beat his great head with his huge, hairy fist ― “there is something which uses matter, but is not of it ― something which might destroy death, but which death can never destroy.”

But in “The Land of Mist”, fourteen years later, Challenger opposes the supernatural and has to be brought round against his will. He champions materialism as his daughter Enid and his friend Malone, both reporters, are about to attend a spiritualist meeting. Malone reluctantly accepts materialism as an intellectual proposition:

“But my instincts are against!” cried Enid. “No, no, never can I believe it.” She threw her arms round the great bull neck. “Don’t tell me, Daddy, that you with all your complex brain and wonderful self are a thing with no more life hereafter than a broken clock!”

“Four buckets of water and a bagful of salts,” said Challenger as he smilingly detached his daughter’s grip. “That’s your daddy, my lass, and you may as well reconcile your mind to it.”

Enid doesn’t and in the end Challenger admits he was wrong. The effort Doyle put into the story was wasted: it’s only a historical curiosity nowadays and seems likely to remain so. To see why the other stories, some much shorter, are much more valuable, simply pick up a copy of the collection in the excellent Wordsworth series.
