Rebel Star - Colin Stuart ****

It would only be fair to expect that we knew everything there is to know about our friendly neighbourhood star, the Sun. After all, without it we certainly wouldn't be here, it's extremely close in astronomical turns and it has been studied for millennia. Yet, as Colin Stuart reveals, there's plenty we still don't know - and of the bits we do apparently know, I was amazed how much was new to me.

I suspect that solar missions and research just don't get the same level of media coverage as, say, missions to Mars with the potential for long-term manned exploration. We are, after all, never going to send people to the Sun. But there are some great stories about attempts to find out more about what is, inevitably, an inhospitable environment. So, for example, Stuart tells the fascinating tale of the Solor and Heliospheric Observatory (SOHO) mission. Launched at the end of 1995, a human error turned the satellite into a $1 billion piece of space junk... or so it seemed. The efforts to get it back going and the final outcome make great reading.

The first part of the book fills in the history of our understanding of the Sun and how it works, while more of the rest covers areas where research is still current and our understanding still remains partial. A lot of this part concentrates on what's going on in the Sun's outer layers and the solar wind and coronal mass ejections that are propelled out from it, sometimes in our direction, which has can have a potentially dire impact on a world dependent on electronics and satellites.

I learned a lot here, and Stuart's enthusiasm is clear. If I have a negative it's that this enthusiasm perhaps carries him away sometimes to give us rather more detail on some of the more abstruse aspects of the complex electromagnetic phenomena that shape sunspots, produce solar flares and more. Similarly, although the likes of Alfven waves and magnetohydrodynamics are essential in getting an understanding what's going on we get, perhaps, a little too much detail for a book aimed at a general audience.

However, if things do get a little over-detailed sometimes, we're soon back to finding out about new and interesting discoveries. Stuart starts most chapters with a scene-setting narrative and throughout the book is packed with information and delights.

The Decline and Fall of the Human Empire - Henry Gee ****

In his last book, Henry Gee impressed with his A (Very) Short History of Life on Earth - this time he zooms in on one very specific aspect of life on Earth - humans - and gives us not just a history, but a prediction of the future - our extinction. The book starts with an entertaining prologue, to an extent bemoaning our obsession with dinosaurs, a story that leads, inexorably towards extinction. This is a fate, Gee points out, that will occur for every species, including our own. We then cover three potential stages of the rise and fall of humanity (the book's title is purposely modelled on Gibbon) - Rise, Fall and Escape. Gee's speciality is palaeontology and in the first section he takes us back to explore as much as we can know from the extremely patchy fossil record of the origins of the human family, the genus Homo and the eventual dominance of Homo sapiens , pushing out any remaining members of other closely related species. As we move onto the Fall section, Gee gives ...

Pagans (SF) - James Alistair Henry *****

There's a fascinating sub-genre of science fiction known as alternate history. The idea is that at some point in the past, history diverged from reality, resulting in a different present. Perhaps the most acclaimed of these books is Kingsley Amis's The Alteration , set in a modern England where there had not been a reformation - but James Alistair Henry arguably does even better by giving us a present where Britain is a third world country, still divided between Celts in the west and Saxons in the East. Neither the Normans nor Christianity have any significant impact. In itself this is a clever idea, but what makes it absolutely excellent is mixing in a police procedural murder mystery, where the investigation is being undertaken by a Celtic DI, Drustan, who has to work in London alongside Aedith, a Saxon reeve of equivalent rank, who also happens to be daughter of the Earl of Mercia. While you could argue about a few historical aspects, it's effectively done and has a plot...

Amazing Worlds of Science Fiction and Science Fact: Keith Cooper ****

There's something appealing (for a reader like me) about a book that brings together science fiction and science fact. I had assumed that the 'Amazing Worlds' part of the title suggested a general overview of the interaction between the two, but Keith Cooper is being literal. This is an examination of exoplanets (planets that orbit a different star to the Sun) as pictured in science fiction and in our best current science, bearing in mind this is a field that is still in the early phases of development. It becomes obvious early on that Cooper, who is a science journalist in his day job, knows his stuff on the fiction side as well as the current science. Of course he brings in the well-known TV and movie tropes (we get a huge amount on Star Trek ), not to mention the likes of Dune, but his coverage of written science fiction goes into much wider picture. He also has consulted some well-known contemporary SF writers such as Alastair Reynolds and Paul McAuley, not just scient...
