Sixty years ago, books about astronomy for general readers were almost unheard of. There were books aimed at enthusiastic amateurs who wanted to explore the night sky with telescopes of their own, but genuine popular science books on the subject are a relatively recent invention. One reason for astronomy’s surge in popularity is a new class of ‘unsolved mysteries’ – always a sure-fire hit with readers – with intriguing names like black holes, dark matter and dark energy.  A second development is the arrival of gorgeously detailed photographs of astronomical objects – which most people will associate with NASA’s Hubble telescope, but can actually be traced back to a book that came out in 1979 called Catalogue of the Universe , which contained the very first true-colour astronomical photograph the general public ever saw. One of that book’s authors was Paul Murdin – co-discoverer of the first black hole, and now a prolific writer whose latest offering is reviewed here. It deals with ...

I love popular science books, but it's a quiet sort of love: it's not often a book like this gets me really excited - but Meet the Neighbours (sorry, I know it's Neighbors, but it grates) does just that.  Once upon a time there was quite a market in books speculating about life on Mars, but of late most Martian titles have focused on getting to and colonising Mars (though often avoiding the 'c' word). Steven Benner drags us back to see the evidence for life having existed there, and does so with a vengeance. (Almost literally - he really lays into those who are dismissive of what evidence there is.) Do we have proof? Well, no - but proofs are for mathematicians. As Benner says 'science does not deal in proof... Rather, it relies on a 'preponderance of evidence' standard to shift the burden of proof.' Benner points out the weird reality that since the Viking landers, which arrived in the 1970s, there hasn't been a mission looking for organic sig...

There have been plenty of good books on black holes, such as Marcus Chown's A Crack in Everything but it's a subject that will always benefit from a different take, and Jonas Enander manages to bring in some new viewpoints as well as exploring the basics of the concept well. After a journey into a black hole described (with the observer's inevitable destruction), we jump back to Michell's dark stars, then start to get the theoretical basis from Einstein and Schwarzschild alongside observational work. This starts, interestingly, with supermassive black holes before getting onto the common or garden variety. Enander's writing style is light and conversational - no danger here of being overwhelmed with technicalities. It's good, readable stuff. In some ways the most interesting part of the book is the final section that addresses the subtitle 'black holes and our place on Earth'. This (admittedly sometimes at quite a stretch) tries to link the study of bla...

This book is something of a reboot. It was Neil deGrasse Tyson's first title, dating back to 1997, but was reissued 'fully revised and updated for the 21st century' in 2024. It's mostly a cut and paste book from the Q&A section in a magazine, despite which (or perhaps because of which) it's one of Tyson's better books. The idea is that the questions are answered by Merlin who is 'a visitor from the Andromeda galaxy who is as old as Earth and who has observed all major scientific events of Earth history.' Although some of the questions are from children (and the illustrations look like they were drawn by one) it's intended to appeal to all ages. The book is split into 13 sections, mostly with astronomical topics (such as Earth, Moon, Planets, Black Holes and Quasars), though with a couple of more physics-based sections including Gravity and Light and Telescopes. The questions themselves vary from entertaining thought experiments such as 'What ...

Jim Baggott is one of the most reliable hands in the business when it comes to exploring complex physics and cosmology issues in an approachable but never over-simplified fashion, so a new Baggott on the shelves is always a treat. For reasons I'll go into in a moment, while the explanation here is as lucid and interesting as possible, I found the topic a little underwhelming. The topic Discordance covers is the Hubble tension - the reality that there are two ways of measuring the Hubble constant that describes the rate of expansion of the universe, both of which are based on solid science, but which don't agree. Admittedly, the distinction is only seven per cent, but in theory they should converge, and as Baggott makes clear, although both of the measurement methods have potential issues, if the tension proves genuine, it puts the most widely accepted version of the Big Bang theory in jeopardy.  The book starts with historical material on how we measure distances in space, the...

Even as someone who rarely gets on with 'bitty' books, I was captivated by this collection of articles based primarily on objects in or relating to the Royal Observatory at Greenwich. After some introductory material introducing the observatory, the Astronomers Royal and the search for means to identify longitude that was instrumental in the setting up of the Royal Observatory in the 1670s, Louise Devoy splits her history across the first ten Astronomers Royal, taking the reader from 1675 to 1955. Each of these sections starts with a pen sketch of the relevant astronomer, from nazmes likely to be known by popular astronomy readers such as Flamsteed and Halley to the more obscure Pond and Spencer Jones. We then get an illustrated guide to a host of objects that are located in the observatory, picture it, or are relevant to it, such as the magnificent-looking Longitude Act of 1714. Inevitably some of the objects are more interesting than others, so, for instance, I couldn't g...

I’ll get onto the details of this specific book a bit further down, but first it’s worth taking a more general look at the series of which it’s the latest instalment. Coming from Reaktion Books, the series is called Kosmos and several of the previous titles have already been reviewed on this site – on Mercury ,  Venus , Mars , Saturn , Uranus and Neptune  and Asteroids . Looking back at those reviews, there’s a clear common theme. They’re all nice-looking, lavishly illustrated books that are packed to overflowing with information – sometimes, as with Mercury or Saturn, on subjects that rarely get a whole book to themselves. On the downside – as far as this site is concerned, anyway – they aren’t popular science books by any meaningful definition of the term.  Here's an analogy. Imagine buying a large-format, nicely illustrated book called, say, The Himalayas . You’d expect it to cover the geography and culture of the region and the history of its exploration, but you’d be...

Astrobiology is an unusual science in that there’s no clear, undisputed evidence that its subject of study – extraterrestrial life – even exists. It’s still an active field of research, though, with observational astronomers scouring the skies for telltale signs of life, and theoreticians tying themselves in knots trying to explain why we haven’t seen any of those signs yet. This book deals almost exclusively with the second of those topics. Before going any further, it’s worth defining exactly what we mean by ‘life’ in this context. If you’d asked Aristotle or Shakespeare or Charles Darwin to define life, they’d give pretty much the same answer, relating to biological processes. If we can’t detect such processes at a distance of many light years, that’s not really a great surprise: the latest generation of telescopes has only just got to the point where it might be possible even in principle. But many popular discussions of extraterrestrial life, this book included, aren’t talking abo...

It's popular science Jim, but not as we know it. There have been plenty of popular science books about the big bang and the origins of the universe (including my own Before the Big Bang ) but this is unique. In part this is because it's bang up to date (so to speak), but more so because rather than present the theories in an approachable fashion, the book dives into the (sometimes extremely heated) disputed debates between theoreticians. It's still popular science as there's no maths, but it gives a real insight into the alternative viewpoints and depth of feeling. We begin with a rapid dash through the history of cosmological ideas, passing rapidly through the steady state/big bang debate (though not covering Hoyle's modified steady state that dealt with the 'early universe' issues), then slow down as we get into the various possibilities that would emerge once inflation arrived on the scene (including, of course, the theories that do away with inflation). ...

I was biased in favour of this great little book even before I started to read it, simply because it’s so short. I’m sure that a lot of people who buy popular science books just want an overview and taster of a subject that’s brand new to them – and that’s likely to work best if the author keeps it short and to the point. Of course, you may want to dig deeper in areas that really interest you, but that’s what Google is for. That basic principle aside, I’m still in awe at how much substance Govert Schilling has managed to cram into this tiny book. It’s essentially about all the things (natural things, I mean, not UFOs or space junk) that can end up on Earth after coming down from outer space. That ranges from the microscopically small particles of cosmic dust that accumulate in our gutters, all the way up to the ten kilometre wide asteroid that wiped out the dinosaurs. Between these extremes are two topics that we’ve reviewed entire books about recently: meteorites ( The Meteorite Hunt...
