Despite three decades of effort and tens of millions of dollars spent on accelerators and their like, it looks as if Particle Physics is coming to a sad end. No new particles beyond those such as the Higgs Boson proposed 50 years ago, and in particular none of those Supersymmetric particles which theorists had hoped would explain that greatest of all scientific mysteries — Dark Matter. Of course there will now be cries for more money and even larger machines, after all the Large Hadron Collider at CERN in Geneva is a mere 27 kilometres in circumference. But wait! Perhaps there is something far more interesting and fundamental at work: Perhaps Particle theorists have misled themselves, and everybody else , through neglecting a philosophical principle at least a thousand years old called ‘Ockham’s Razor’ (OR), named after a mediaeval monk called Friar Ockham.

At the heart of the Scientific Method is the business of Hypothesis Testing, which is where OR comes in. It states “Always prefer the simplest hypothesis first” and that, I suggest, is where Particle Theorists went so horribly wrong. Their “Standard Model” — as they call it, is fiendishly complex — what with its Quarks, Gluons, ‘Asymptotic Freedom’ and so on and so on. How do we measure complexity in Science? By the number of ‘Free Parameters’ (FPs) needed to describe a theory. One way you can think of them is to say they are arbitrary numbers brought into a theory to force it to fit the experimental data. A ‘good theory’ doesn’t need many FPs because it fits the experimental world naturally(for instance Newton’s very successful Theory of Gravitation has only 2 FP s) The so called Standard Model of Particle Physics needs no less than 18 FP s which has always suggested that it is an ugly and unnatural construct. It should be no surprise then to find now that it actually looks to be wrong.

So why did theorists construct such an ugly model in the first place, mostly back in the 1960’s and 70’s? Probably because they didn’t understand just how fundamental OR is. And there’s some excuse for them — because the Philosophers of Science, the self-appointed arbiters of the Scientific Method, didn’t understand OR themselves. Even Einstein, who relied on it extensively, waffled about some plastic ‘God’.

As I see it Hypothesis Testing works like this. You have some data-points, with error bars of course, and you have your hypothesis which generates a smooth curve which you must try to fit through those points. If there are lot of points the Odds on your hypothetical curve fitting them all by chance must be small. So if it does so fit then the Odds are that the hypothesis is probably right. If it doesn’t fit then you can always complexify your hypothesis ,so twisting your hypothetical curve until it does fit. But you can see that’s not a very convincing way to proceed, because eventually you are always going to force a fit. In that case the Odds in favour of it being actually right vanish. And that, I would suggest is what happened to Particle Theory, starting half a century a century ago.

There’s nothing fundamentally wrong with modifying a theory to fit the facts, after all that’s how science progresses. But you have to be very frugal in doing so. Only introduce a new concept (FP) into your theory if it fits at the very least two more data points than its simpler predecessor. And that’s hard to do, but it won’t degrade the Odds on it being right. But if it only fits one more data point the Odds will generally degrade dramatically. And that’s what Particle Physicists were tempted to do; making names for themselves at the expense of undermining the Odds on their so called ‘Standard Model’ theory. And that’s why almost nobody believes in their theory anymore. It’s as if they’d undermined their currency by printing too many notes. It works for a while — then collapses!

I am not a Particle Physicist, thank God, I am an Astrophysicist. And what worries me is that those same Particle theorists have dragged their own dodgy practices into our subject, with predictably unhealthy consequences. Take “Dark Energy”, an entirely artificial concept dragged into Cosmology by a particle theorist called Ed Turner from the Fermi Lab (and the University of Chicago). Now astronomers are raising hundreds of millions of dollars to chase this fantasy around the cosmos when there’s no justification for doing so, none at all. It was a thoughtless quick-fix extra Free Parameter to fit the apparent acceleration of Cosmic Expansion inferred from Supernova measurements in 1998. Had its introduction explained TWO or more discrepancies between theory and observation we might have welcomed it in. But it didn’t. So it should never have been introduced in the first place. Never!

PS Actually the situation is far worse than I am implying because the bloody particle theorists who have undermined their own subject actually introduced two more unnecessary FPs into Cosmology before Dark Energy: ‘Inflation’ to cure Isotropy and nothing else, and ‘Dark Matter’ to fix the Cosmic chemical abundances. We need to throw them out too.

So where do we go from here? Cosmology should chuck out Dark Energy, Inflation and Dark Matter and start again without them. As for Particle Physics I suspect that they may have to go back 50 years and try to reconstruct a more parsimonious theory of particle interactions than the ‘Standard Model based on quarks and gluons. In his wonderful book ‘Constructing Quarks’ Andrew Pickering (Univ. Chicago Press 1981) suggested that that theory was a social construct anyway, the product of trendy acclamation, rather than sober assessment.

More generally all of us need to understand the process of Hypothesis Testing on which the modern world of ideas is entirely built. Because if that isn’t sound ,God help us all.

Archaeologists use tree-rings to date events several thousand years ago, climate scientists use ice-cores to decipher the state of the atmosphere as it was several hundred thousand years ago and astronomers bore holes in the Cosmos that potentially tell us of the Universe as it was billions of years in the past. But all these signals need some ingenious deciphering to get at the truth.

Look at the spectrum below, taken with the VLT, the world’s. most powerful optical telescope, sited high in the Chilean Andes. What is so remarkable about the spectrum, which stretches from the violet to the deep red, are all the dark lines imprinted upon it as the light from a very distant quasar has traversed Space on its immense journey to reach us. They probably have a fascinating tale to tell, far more momentous than the Rosetta Stone. But what is that tale? Why not have a go at cracking it?

This image, originally entitled “Fingerprints of the early Universe” can be dowloaded from The European Southern Observatory’s spectacular website under /images/ ‘Quasars and Black Holes’. It is an extremely deep spectrum of the Quasar (or ‘QSO’ standing for ‘Quasi-Stellar Object’) HE 0945-1050 (at redshift 3) taken with the UVES instrument on their Very Large Telescope (VLT) . What is remarkable about it is the presence of so many dark lines imposed on the spectrum, each the result of an absorbing cloud of gas lying along the line of sight to the quasar, which is several billion light years away from us. ( Acknowledge V. D’Odoricco, Osservatorio Astronomico di Trieste, Italy)

Experts have been staring at such QSO Absorption Line Systems (QSOALS for short, or ‘Spectral Ghosts’ as I prefer to call them) for over 50 years years now, and have come up with some intriguing clues. The lines, which have nothing to do with the quasar itself, are caused by atoms in distant clouds of gas lying at different redshifts ( or distances, because of the expansion of the Universe) along the line of sight. They know that from measuring the ratios of the wavelengths of those lines, ratios which in many cases are identical to to the ratios of spectral lines from ordinary atoms in the laboratory such as Hydrogen, Magnesium, Carbon, Oxygen, and so on. Since most of those atoms can only be made inside stars we infer that the mysterious clouds must also contain stars. But the only gas-clouds we know of containing stars are Galaxies, huge whirlpools of gas and stars , structures like the Andromeda Nebula and our own home The Milky Way ( See our post “Galaxy Gallery” for images). So what we must be seeing are the atoms in galaxies at different redshifts (distances away) intercepting and scattering out discreet wavelengths as the light-beam passes through them. Hence the spectrum is the log of an immense journey, and of all the encounters with galaxies which the light beam has made on its way from the Quasar to the Earth. Right? Well no.

Why not? Because there are about a hundred times too many black absorption lines to be accounted for by ordinary galaxies. A hundred times! That’s going to take some explaining. The experts of course have such an explanation: they say galaxies must simply be a hundred times bigger than we thought; they must have a vast invisible halo of gas around them which intercepts quasar light and etches all those lines we can see.

But don’t you think that explanation sounds just too glib, too ad hoc, rather too much like a child’s lie or the fairy tale about The Emperor’s New Clothes? I do. I think it’s a blatant attempt to brush a fascinating mystery under the carpet. Experts, especially those who make their living out of their expertise, don’t like to admit to mysteries, because they might undermine their claims to expertise. How often have you heard your doctor admit; “To be honest Mr. Jones I have no bloody idea what’s wrong with you.”

Of course the QSOALS experts claim to have at least some evidence in support of their Giant Halo Hypothesis. But if you look at that evidence very carefully, it’s not convincing at all; at least that’s what I think. I’ve got an alternative explanation for the dark lines, even more dramatic than Halos, but I won’t go into that here, because it too has its detractors.

Instead, the purpose of this post, is simply to point out that there is a great mystery out there and to encourage curious outsiders to have a go at solving it. After all The Rosetta Stone itself was solved by a young self-taught outsider, Jean-Francois Champollion who had taught himself Coptic Greek, which turned out to be the key … but that’s another fascinating story.

If it seems ridiculous to suggest that any but a professional astrophysicist (as I am myself) could make a serious contribution to this problem, that ignores how profoundly the Internet has changed Science. Here the germane facts are few. The relevant data is available for all to download from public archives, as are the existing scientific papers on the subject. And just remember that modern academics have become far too busy to really think any more. So you won’t have much serious competition from them.

So why not have a go? Deciphering the Cosmic Rosetta Stone will be far more exciting, and momentous, than cracking Egyptian history. But don’t expect it to come without effort. A couple of thousand hours of focussed reading should get one up to speed however. And here’s a useful tip to start: find out what the ‘ADS’ is ( it’s got something to do with NASA) and start using it.

Good luck. If nothing else you could have a hell of a lot of fun.

My trade as an astronomer , involves travelling to the very darkest spots on Earth, peering up to see what is there, and returning to report to you, my fellow humans. You poor devils can’t see much of the splendour because you have blinded yourselves with artificial lighting.

These expeditions into the dark started in the Arizona desert, then on to the Warumbungles in the Australian bush, to the island peaks of Hawaii and La Palma, and finally to La Silla up in the Chilean Andes where I measured the darkness in between the stars at 22.5 Blue magnitudes per square arc second. In my ignorance I was impressed though I was disappointed to see little more from up up there with the naked eye than I could espy from a moonless beach in Wales. ‘Why not?’ I wondered.

It turns out that the rod cells in the eye, which enable us to see in the dark — if we treat them properly, are critically dependent on Oxygen. Climb a mountain, where of course all our telescopes are constructed, and you’ve lost it. I discovered that by accident when I woke up in the bottom of my little sailing boat up a remote creek in West Wales to find a colossal glow several moon-widths across, peering down at me from on high. Yes I’d had a few pints but….surely…. It took minutes to realize that I was being watched by the Andromeda Nebula, our fellow Spiral galaxy, which I’d never seen before, even from those remote mountain peaks. [Try it for yourself on a moonless night in summer. Get as far away as you can from city lights, and go to sleep in the open (that ‘dark-adapts’ ones eyes), then wake and look up — and with any luck you might see a marvel you will never forget.]

This is a composite image showing just how big The Andromeda galaxy is compared to the Moon. It’s really worth looking for. Copyright Adam Block and Steve Puckett.

Why hadn’t the big telescopes I’d been using make much difference? First because their fields of view are far too small. Second because the light you want to see is accompanied by much more background sky-light that you don’t. The big mirror amplifies both, only weakly improving the contrast. And that is what one needs to discern the dimmest structures in the universe — more contrast!

When I joined the Hubble Space Telescope Team it was natural to suppose that seen from up there in Space the sky would be really dark. But no. In between the planets drift tiny motes of dust which reflect sunlight back down into our dark — the so called Zodiacal Light — which you can actually see , if you know where to look. So disappointment once again.

Perhaps, if we could escape from the Solar System? But no again; there will still be faint starlight out there from the Milky Way and scattered starlight too. What a disappointment. Is there nowhere in the cosmos from where we could see the Universe as it really is? What about out there between the galaxies out in Intergalactic Space? You and I will never be able to go out there, but perhaps our distant descendants?

If I couldn’t go at least I could calculate how dark it ought to be out in that farthest, remotest, darkest immensity, an unimaginable distance away from any luminous star. It wouldn’t be absolutely black of course because some light would still be leaking from the nearest galaxies several million light years away.

What a shock I was to get from my calculation when I finally made it in my eighties. Out there the sky would have a brightnesss, or rather a dimness of 31.5 Blue magnitudes per square arc second, 9 magnitudes darker than the darkest site on Earth (Remember? 22.5 of the same magnitudes in the Andes). Now 5 magnitudes is one hundred by definition, so 9 magnitudes is one hundred times forty, or four thousand. Turn the calculation around and you can see why I was stunned. We live on a planet where the darkest night sky we will ever see is four thousand times brighter than it has to be if we are ever to see the Universe properly . We’re dazzled, blinded, blind. It is far more likely than not that we are blinded to most of the structures out there, and that all we will ever see, for all our technology, is a tiny fraction of the true Universe. Think on that. Knowing what we cannot know is sometimes more informative than knowing what we can.

If you want to see how the calculation was done go to:

Morgan, the protagonist in the Written in the Stars quartet, and I, have spent our working lives studying Galaxies. This is the first one he saw when he was looking through the 36-inch telescope at Steward Observatory atop Kitt Peak in Arizona, back in 1969.

Spiral Galaxy NGC 7331 in the constellation of Pegasus, at top. Courtesy, Vicent Peris, University of Valencia.

This particular image was taken much later with a huge telescope 3.5 meters in diameter fitted with an ultra-sensitive electronic camera integrating the light for two whole hours. So imagine how little if anything Morgan would see with the naked eye which integrates for all of a tenth of a second, through his much smaller telescope: virtually nothing at all. That’s why he struggled for half an hour to even convince himself that it must be there, and why he felt that studying galaxies could become the lifetime challenge he was looking for. And so it came to be.

NGC 7331 just happened to be the nearest Spiral overhead his telescope at the time. All the spiky stars are stars in our own galaxy the Milky Way, just hundreds of light-years away, while the spiral lies 45 Million light years beyond them, yet is one of the closest such giant spirals to us.It is about a hundred thousand light-years across! The smaller galaxies lower down are even farther off. Morgan was to spend most of his astronomical life studying galaxies whose light had set out towards him when dinosaurs still ruled the Earth, and some so far away that the Sun and Earth didn’t even exist when their light was emitted.

Even now we know little about these beasts; they are full of mysteries. For instance they spin so fast that they ought to fly to bits. So what holds them together; certainly not the stars we can see in them — their gravitational force would be far too weak. Some astronomers mutter about “Dark Matter”, but what is that, and why have we detected no sign of it after 50 years of searching with every ingenious means we can think of? Then we have no idea how galaxies formed, not if the Universe is really expanding, for their infant stages would have been far too fragile to survive the Big Bang. Galaxies remain a challenge for any young person who would like to spend their lives trying to understand what is out there.

Hard as it was to see, it turns out that NGC 7331 is one of the most visible galaxies there are. Over the course of 50 years Morgan and his colleagues were to find much much dimmer specimens using radio waves instead of light. The next montage shows some typical specimens first located with the Parkes Radio Telescope, then imaged in visible colours with the Sloan optical Telescope in New Mexico, both absolutely state of the art instruments. Its worth studying this montage:

Galaxies first found independently of their light signal in the radio, then imaged optically in several colours (Courtesy Julianne Dalcanton, University if Washington, Seattle).

Believe it or not every postage-stamp contains a galaxy, some so dim one can barely spot them. This illustrates the “Visibility of Galaxies” problem which Morgan discovered in that caravan on the Teifi estuary back in 1975 [See my book Against The Fall of Night]. The problem is that, dark as it appears, the night sky is not absolutely dark so that any galaxy dimmer than our sky would be invisible. And why not? Could most of the structure of the Universe be hidden from sight? Morgan, Cotteridge, Cockle and other astronomers spent their careers wrangling over that question. There’s a great deal to think about here.

Broadly speaking there are two types of giant galaxy, Spirals as above, and Ellipticals. As we can see next, Ellipticals look like giant swarms of bees ( actually very old stars).

The Coma Cluster of Galaxies centred on the supergiant Elliptical NGC 4889 taken with the Hubble Space Telescope, courtesy ESA/NASA.

Ellipticals are just as mysterious as Spirals but in somewhat different ways. For instance NGC 4889 seen here fades imperceptibly into the sky; so where does it end and therefore how big and how massive is it? And why are Giant Ellipticals only found in Clusters? And where have the cold gas and the young blue stars gone that light up Spirals? And why do some of them, like this one, have colossal Black Holes in their cores? And how do these giant Clusters hold together when the gravitational forces required are hundreds of times too weak , if only visible material is responsible. Once again we run into speculations about “Dark Matter” which sound a bit like The Emperor’s New Clothes to me. In other words we are mired in mysteries which challenge anyone with Curiosity. By the way, this colossus is about 300 Million light years away, its light having set out towards us even before Dinosaurs evolved and 50 million years before the great Permian-Triassic extinction, which wiped out 90 percent of the the species on Earth. Yet in astronomical terms it’s almost next door, only seven times as far away as our Spiral friend NGC 7331.

We said most galaxies dwell in Clusters containing anything between a few and tens of thousands. Here is a very large Cluster Abell 1689, 2 Billion, not Million, light years away:

Galaxy Cluster Abell 1689 imaged with the Hubble Space Telescope (Courtesy ESA/NASA)

The further away we search , the further back in time, the greater cosmic mysteries become. For instance what you can actually see here is about one per cent of the Mass actually present. We know that because the galaxies in the cluster are whizzing about so fast that the cluster would have dispersed unless there are overwhelming amounts of “Dark Matter” holding it together [Or else there’s something even more mysterious going on.] This dramatic tendency of galaxies to cluster made it very difficult indeed for Tom Morgan and his friends to find “Hidden Galaxies” because the hidden ones would tend to get lost amid a crowd of ‘Visibles’, requiring great precision to get at the truth.

This, believe it or not, is the identical galaxy NGC 7331 to the one at the top of this post, though the image is flipped left to right..I have put it in for several reasons. First it is in colour because it was made up from several images taken through different colour filters with camera WFC- 3 ( Morgan & co.) on Hubble . This colour information paints a very different picture of the galaxy, which is evidently choked in smoke, so that much of it is hidden. Using the old photographic plates little of this was evident and astronomers were convinced galaxies were transparent. Morgan was practically the first astronomer to realise they were not, largely because he had early access to one of the first electronic cameras. Then there is the atmosphere which blocks off all the ultraviolet, and most of the infra-red radiation included in this picture taken from Space. The general point is that our understanding of the universe is very much constrained by the instruments we have to study it. Space astronomy has widened our spectrum by more than a billion and it may take generations to understand the implications. It’s all too easy to rush to judgement, and to see only what we want to see. Copyright ESA/NASA

When we professional astronomers talk to the public we tend, for sociological reasons, to emphasise what we do know, as against what we do not. Now that I’m retired I can admit that most of the time, at least in extragalactic astronomy, we have little idea of what is really going on. Yes there are fools only too ready to rush in with half-baked explanations such as “Dark Matter” or “Dark Energy”, but I doubt that many will stand the test of time because they ignore Ockham’s Razor, a very profound and vital principle of Common Sense [See my book Thinking For Ourselves or a post on this site entitled Fuzzy Thinking and Ockham’s Razor]. In the mean time they not only rob us of mystery and wonder but they can hold up the search for deeper truths. For instance the invention of fictional “Land Bridges” held back the discovery of Continental Drift by a century.

I hope this post encourages readers, especially the young at heart, to retain their sense of mystery because, as Einstein put it : ” The most beautiful thing we can experience is the mysterious. It is the source of all true art and science”.

You can look up hundreds of more wondrous images of galaxies by going either to, NASA’s Space Telescope institute, or the European Southern Observatory which runs the world’s largest optical telescope (The ‘VLT’) in the Chilean Andes. But beware of beautiful coloured images which look like pizza advertisements; real galaxies don’t look anything like that, they’re far more subtle and infinitely more difficult to decode.

Parkes Radio Telescope New South Wales

The Parkes Radio Telescope in New South Wales Australia after it had been fitted with the new Multi-beam receiver system designed to pick up the Hydrogen signals from galaxies with about a thousand times the speed of any previous instrument. It has 13 separate dual-beams and 26 receivers cooled down close to absolute zero (minus 273 degrees C) up in the receiver cabin which is the size of a small house. Up there the very weak signals are mixed with a maser and the lower frequency output signals are sent down to the tower where they are processed by specially designed and very powerful digital correlators to look for the characteristic 21- centimetre wavelength signal of Cosmic Hydrogen. With it Morgan and his Australian colleagues surveyed two thirds of the sky and found over 5,000 such sources among which they hoped to find Dark Galaxies.[See Written in the Stars quartet of novels under ‘My Books’ Category]

The Dish has a romantic background. It was built by Taffy Bowen who, together with Hanbury-Brown, devised the night-fighter radar system which put an end to the Nazi blitzes in 1942. Starting at Bawdsey Manor in 1936 they devised means to cram radar systems into aircraft — which was fiendishly difficult to do in those days when radar waves were 10 metres long. But somehow, supported by Air Marshall Dowding, the head of RAF Fighter Command, they eventually did so.

In 1941 Bowen was sent to the US with his notorious ‘Suitcase Full of Secrets’ to teach the Americans how to build effective radars [See my book ‘History of the Brits‘ for that story ]. Later Bowen came to Sydney to direct the CSIRO Radiophysics Lab and the grateful Americans gave him half the money to build the Parkes dish which was completed in 1961. In 1962 Cyril Hazard from the University of Sydney used it to locate the first Quasar when the radio source 3C-273 passed behind the Moon. The disappearance and re-appearance of the radio-signal enabled Hazard to get a very precise position for it — which corresponded to that of a moderately bright star. An optical spectrum of that star showed it to have a high redshift and so to be an enormous distance away. The first Quasar Stellar Radio Source, or ‘Quasar’ had been discovered — starting off a whole new branch of Astrophysics — leading eventually to the discovery that they are Super Massive Black Holes.

Hanbury-Brown — after whom the term “Boffin” was coined, also made his name later as an astronomer in Australia. He it was who completed the night-fighter radar system which did for the Blitz and saved Britain [He features extensively in my Second World War scientific novel ‘Strangle‘ described in ‘My Books’ Category] .

The main weakness of radio telescopes is the non-existence of a ‘radio-camera’ which can look in more than one direction at once. The big box you can see at the focus was the first successful attempt at one. It has got 26 receivers looking in 13 adjacent but different directions at once — which allowed us to survey two thirds of the entire sky for Hydrogen gas in deep space — in the hope of locating Hidden Galaxies (see our Post ‘Hidden Galaxies‘). Unfortunately we then totally cocked things up by mis-identifying all the 5000 such sources we found with conspicuous optical galaxies , which is all too easy to do when galaxies are so highly clustered together in Space. Actually many of the Parkes sources are indeed dim or dark galaxies or gas clouds. Astronomy is hard….but very exciting!

A novel about astronomical research

The last of the 4 novels of a saga set amidst Space exploration and astronomical research between 1965 and 2015 when the extragalactic universe truly hove into sight for the first time. Voyaging to a new continent is hard enough, understanding it when you first arrive is harder still. Columbus imagined he was in Japan; in Cochin Vasco da Gama saw little beyond sandalwood and spices; Pissaro couldn’t tear his greedy eyes off Inca gold. What will the first voyagers make of the extragalactic universe as seen from Space? What delusions will comfort them, what preconceptions will blind them to the truth? Morgan and his colleagues, friends and enemies struggle to make sense of a vast new firmament none could have foreseen. Starting at the great radio telescope in Australia Morgan confidently expects to find his own obsession, his Hidden Galaxies. But the results will come as a shock. Or could there be some deep misunderstanding? Meanwhile the race is on to repair and refurbish the Hubble Space Telescope following the Columbia tragedy. Back in Wales Curly and Petrel struggle to make sense of the Sea Empress disaster which chokes their Pembrokeshire coast in oil. Love comes to Morgan from far far away as his university decides to sack him. Old Salt is on his last legs but is not too weak to take on the Establishment, while Frank has persuaded Europe to build the world’s largest telescope. The closest family relationships are poisoned by jealousy; Petrel changes tack; Morgan goes to Venice and ‘hears the horns of elfland faintly blowing’. But has he become unbalanced, as many of his colleagues believe? A great oak falls; Jack Cockle departs. Whose dreams will come true, whose hopes will be dashed`?

The deepest image ever taken of the Universe. It was taken with the WFC_3 camera which Morgan helped to design and exploit towards the end of his career. Does it prove that the Universe isn’t expanding? Looks like it. Morgan thought there was something very strange going on here. It can see back 12 billion years, to before the Sun was formed. The study is called “the Ultraviolet Coverage of the Hubble Ultra Deep Field (UVUDF) project.” Courtesy ESA/NASA

A novel about astronomical research

The third novel in the saga of Space exploration is a mix of triumph, disaster and surprise. The Space Shuttle Challenger blows up killing all the astronauts. A colossal Hidden Galaxy turns up crouching beneath the sky. Morgan unexpectedly acquires a daughter and discovers, to general surprise, that spiral galaxies are heavily veiled in smoke. The Hubble Space Telescope gets launched, but with a crippled mirror; ways must be found to put it right. Finally the first very deep images come back from Space; but what do they mean? Rows break out between the teams. Frank builds an observatory on a remote Atlantic isle. Bob Salt intervenes in the Cold War while, deep behind the Iron Curtain Morgan has two encounters which will change his life. But then he almost loses it all. The action shuttles back and forth between Wales, Cape Canaveral, The Caucasus, Castel Gandolfo, the Arabian mountains, Baltimore, the Canary Islands, India, Australia, Paris….. See ‘Against the Fall of Night‘ and ‘The Whispering Sky’ for the two previous novels, with same main characters and ‘Beyond the Western Stars’ its successor and the finale to the saga.

A montage of galaxies found by Morgan and his team solely based on their radio signals, thus it shouldn’t be influenced by their optical characteristics. Indeed such a search could in principle find entirely dark galaxies. As you can see some of the galaxies are almost invisible, but not quite. Perhaps most interesting are the six specimens bottom right, because they are all colossal Giants containing more Hydrogen (which emits the radio signal) than our Milky way. But as you can see some are very dim even so. Image courtesy of Prof. Julianne Dalcanton, University of. Washington Seattle, and the Sloan Digital Sky Survey.

A novel about astronomical research

The Whispering Sky is the second of a quartet of self-contained novels relating the saga of two astronomers, originally boyhood friends, caught up in humankind’s endeavour to explore the Universe from Space. Thanks to his feud with Bellfounder – the machiavellian Astronomer-Royal [See ‘Against the Fall of Night’, first in the quartet], Tom Morgan has been thrown out of British Astronomy. Cheated out of the post he had been promised he struggles precariously in Europe to try and prove that his theory of Hidden Galaxies is right. That takes him to far flung observatories from the peaks of the Andes to the Cape of South Africa. Meanwhile the US is building the Shuttle to launch a large telescope into orbit but demands European participation in the venture. Frank Cotteridge, by now Bellfounder’s protégé, is tasked with lighting the European fuse. At conferences and in laboratories across the Continent the struggle begins to try and build the first electronic camera, to act as the great telescope’s eyes. In the 1970’s that looked impossible. And yet without such eyes the telescope will be blind. The race against the clock, and with rivals in California, begins. Personal and professional tensions drive wedges between the two friends while the race for Space forces them to rely ever more closely upon one another. Morgan rashly plans his revenge on Bellfounder, a battle only one of them can possibly survive.

This illustration shows the NASA/ESA Hubble Space Telescope in its high orbit 600 kilometres above Earth. Morgan and Cotteridge began working on its design back in 1977, 13 years before launch. Courtesy ESA/NASA.

At the same time Morgan is struggling, as a single parent, to bring up his son Curly and hold on to him in a bitter custody battle. When he loses, Curly is whisked away to Australia but then escapes and gets hopelessly lost in the bush.

The author was himself a professional astronomer, and a single parent, throughout this epoch. From 1976 until 2010 he was a key member of the Hubble Space Telescope team. Hubble’s story, our story, which he has been preparing to write for 20 years, is packed with dreams, heroes, shocks, villains, and the odd rare triumph. Like one of Magellan’s crew he saw great wonders and has tall tales to tell; the fight to get born, the Challenger disaster, the crippled mirror, the astronaut repair-missions, cancellation following the Columbia tragedy, renaissance, the race to prevent the space-craft dying, the huge discoveries… he was there; he was there; he was there.

A novel about astronomical research

  Against the Fall of Night is a story about astronomical research, of one man’s battle to prove that there is another universe out there, hidden below the light of the night sky. It is centred in that glorious epoch between 1960 and 2010 when mankind at last broke free from Earth’s atmosphere and had to confront the Cosmos as it truly is: vast, mysterious  and very likely beyond his puny comprehension. But will he realise that, or seize on comforting fairy stories that will only serve to conceal the truth?  

Tom Morgan the protagonist, often facing starkly contradictory evidence, is suspended between exultation and despair. Half heroic and half tragic, his quest becomes an obsession which drives him round the world in search of the killer clue, forces him into confrontation with a highly sceptical Establishment.

Starting in the swinging London of the mid-sixties  the action moves on to remote observatories in Arizona, Australia, Africa, the Soviet Union, the Andes, Hawaii, …..and culminates on the launch pad at Cape Canaveral, for Morgan’s quest eventually leads him to become one of the designers of the Hubble Space Telescope.

Where so much of our story really began. This is Steward Observatory perched atop Kitt Peak, a mile above the Sonora Desert in Arizona. The 36-inch telescope left was used to find the Crab optical pulsar, and in the cylindrical 90-inch (centre) Morgan first started to think about Hidden Galaxies. Observers like him from the University of Arizona slept in the small buildings bottom right. The monster ‘4-metre’ was added later.

Morgan is no scientific cipher. An emotional single parent, he needs friends, comrades and lovers. He climbs, flies a glider, sails his boat and forges Van Gogh’s. Worse still he enjoys fighting a growing phalanx of enemies led by Sir Adrian Bellfounder, the unscrupulous Astronomer Royal. He is an extreme type: individual, competitive, irascible, passionate, imprudent. Throughout what will be a quartet, each part completely self-contained, but with the same central characters and spine plot, (see below) he is contrasted with his opposite, and lifelong friend and rival Frank, who has his own astronomical tale to tell. Frank  is the attractive, balanced, unselfish character who can get men and women to work together to build dreams beyond the reach of any single one. The story starts with the two friends leaving their universities, with very different prospects before them.

The author was himself a professional astronomer throughout this epoch. From 1976 until 2010  he was  a key member of the Hubble Space Telescope team. Hubble’s story, our story, which he had been preparing to write for 20 years, is packed with dreams, heroes, shocks, villains, and the odd rare triumph. Like one of Magellan’s crew he saw great wonders and has tall tales to tell; the fight to get born, the Challenger disaster, the crippled mirror, the astronaut repair missions, cancellation following the Columbia tragedy, renaissance, the race to prevent the space-craft dying, the huge discoveries… he was there; he was there; he was there. He knew the people, felt the pain, drank the wine.
