ESA‘s roadmap to Earth-like planets
I have a new story published over at ESA:

“ESA is launching a new initiative to develop a roadmap for finding Earth-like planets. Searching for rocky planets around other stars, in the hopes of finding an Earth-like world, is a top scientific goal in ESA's Cosmic Vision programme. …”

Space particles play with the mind
New Scientist issue 2658

“It’s hardly unusual to find things flashing into your head as you fall asleep, but as Christer Fuglesang was settling down on his first night aboard the International Space Station it happened quite literally. It was December 2006, and as the European Space Agency astronaut floated, eyes closed, in his sleeping bag he suddenly saw a spot of white light surrounded by a faint halo. It vanished in an instant but Fuglesang realised immediately what it was. "I had heard about these things and so was very happy to have finally experienced one," he says.

Since Buzz Aldrin and Neil Armstrong first reported these flashes during the Apollo 11 mission to the moon in 1969, dozens of astronauts have seen them. An investigation by NASA after Apollo 11 returned concluded that the flashes, sometimes called "phosphenes", were a consequence of fast-moving particles, most probably cosmic rays, ...”

Fire & ice: What really happened to water on Mars
New Scientist issue 2657

“SINCE the Viking orbiters beamed back the first tantalising images of water-cut features on Mars in the 1970s, NASA's mantra for the Red Planet has been simple: "follow the water". Working out when Mars had liquid water on its surface, and where that water went, they reason, will provide vital clues about whether Mars could once have harboured life, and whether life could cling on today.

Since then a long line of orbiters, landers and rovers have searched the Martian surface for signs of where water once flowed. The latest, NASA's Phoenix lander, is scheduled to reach the surface of Mars on 25 May. If all goes well, it could be the first lander to actually hold Martian water in its robotic hands, and will answer. …”

Tunguska: The Truth
I have the cover story on BBC Sky at Night’s June issue:

“They say that lightning never strikes twice.  Most people think the same about asteroid impacts but some researchers aren’t so sure.  Take the devastating 30 June 1908 impact over Tunguska in Siberia.

It was about 7:15am when, out of the brilliant summer sky flashed a meteorite, a really big one.  As it ploughed onwards, it left a pillar of smoke hanging across the sky marking its passage.

It never reached the ground.  Instead, at an altitude of 16 kilometres it detonated with energy estimated to be around a thousand times greater than the Hiroshima atomic bomb. The resulting blast wave swept across an area of 2150 square kilometres.  Had there been a city underneath, it would have been devastated, with hundreds of thousands of casualties. …”

You can read the full story in the June issue of BBC Sky At Night magazine.  You can also listen to an interview with me about Tunguska by the magazine’s editor Graham Southorn.  It is available on the magazine’s second podcast episode, available here.

ESA and space tourism
I have a new story published by ESA:

“The general public's interest in suborbital flying is now substantial. Such flights could offer a realistic opportunity to 'touch' space by experiencing weightlessness and seeing the curvature of the Earth's limb. Being so closely related to ESA's 'core business', the Agency is observing these developments with interest, and is now presenting its position on privately funded suborbital spaceflight. …”

The Sun Kings Shortlisted for the Royal Society Science Book Prizes
Three weeks ago, I announced that The Sun Kings had been longlisted by The Royal Society for their 2008 Science Book Prizes.  Well, it is with a cocktail of excitement and disbelief that I can announce today that the judges have gone on to shortlist my book.
The judges said: “The Sun Kings is a real page turner which will open your eyes to the number of scientific discoveries throughout history that might have been lost. The real majesty and power of the sun shines through and, if you’ve never given a second thought to your nearest star, you will now.”
There are five other books on the shortlist and, as when the longlist was announced, I am thrilled beyond measure to be in the company of such authors.

The Martian Water Cycle and Climate
I have a new story published in three parts over at ESA.  First is the introduction:
“Even in the clearest, bluest sky on Earth, there is still water vapour in our atmosphere. If you could condense all the water vapour out of the atmosphere above you, it would form a layer of water two centimetres deep. On Mars today, there is also water vapour in the atmosphere but it would create a layer just 10 micrometres thick.”

Then there are two interviews:
“The Martian water cycle and climate with Robert Haberle, NASA Ames Research Center and Oleg Korablev, Space Research Institute, Moscow, Russia.”

“Frost and ice below the Martian surface with Bill Feldman, Planetary Science Institute, Arizona, USA and Bernard Schmitt, Laboratoire de Planetologie de Grenoble, France.”

Deep Space “with brains”!
There have been a couple more flattering reviews of Deep Space. The Daily Express described it as a ‘sumptuously illustrated voyage through the universe’ and say that the “commentary clearly explains the evolution of the cosmos.”
You can read the full review in the 29 February 2008 edition of The Daily Express.

In the BBC Sky at Night magazine, Sean Blair gives the book four stars out of five.  He describes the voyage-like nature of the book into the deepest regions of space and says “It would easy to get lost on such a journey, but Clark keeps his readers oriented.  The graphical content remains strong even as we move to things unseen, with simulations depicting the dark matter thought to underpin galaxies and the dark energy driving the universe apart.  There are lots of astronomical picture books around but this one comes with brains too.’
You can read the full review in the May 2008 issue of the BBC Sky at Night magazine.

I am also pleased to announce that I am working on a new book with the same publisher – more details soon!

Total solar eclipse in China
I will be acting as your astronomy guide on a 13-day tour to China next year to see the total solar eclipse. The tour is organised by Wendy Wu Tours. It leaves Heathrow on 14th July 2009 and returns on 26th. It travels from Beijing to Xian to see the Terracotta Warriors and on to Hangzhou. We shall view the eclipse on the 22nd July from the banks of the Qiantang River.
Our tour will then progress to Suzhou and Shanghai. All sorts of treats are in store, from rickshaw rides to boat trips, from traditional food and tea to gardens and buildings.  I am thrilled to be offered the opportunity to see the wonders of China and share the eclipse experience with you.

The Sun Kings Longlisted for the Royal Society Science Book PrizesIt is with enormous pleasure that I can report that The Sun Kings has been longlisted by the Royal Society for their science book prizes 2008. The longlist contains 12 books and I am humbled to be in company of so many excellent authors.
About The Sun Kings, the judges said: "A wonderful historical biography. This 19th century melodrama gets you straight into the science of sun spots.  It has everything great characters, knives, guns and illicit relationships!"
About the longlist in general, Professor Jonathan Ashmore, Chair of the judges said: "We found it very hard to choose just twelve books. None of us had realised how many eligible titles had been published over the past year. The range of styles and topics was truly astonishing. It was both fascinating and exciting to be surrounded by the most recently published science books, in some cases almost hot off the press. The books we have selected for the longlist reflect, we think, the high standard of the entries."

Deep Space: “jaw-dropping images”
Astronomy Now magazine has positively reviewed my new book, Deep Space, published by Quercus Books.  Assistant Editor Kulvinder Singh Chadha says, “Deep Space is more than just a picture book. Contrary to what tended to be the case in the past, the text isn’t just tacked on as an afterthought.  It is integral to understanding what is going on in the images. Clark respects the reader, and explains the important aspects of cosmology and space science in detailed yet succinct terms. …”

Solar flares set the Sun quaking
I have another new story published by ESA: 
“Data from the ESA/NASA spacecraft SOHO shows clearly that powerful starquakes ripple around the Sun in the wake of mighty solar flares that explode above its surface. The observations give solar physicists new insight into a long-running solar mystery and may even provide a way of studying other stars. …”

Sorry things have been quiet
I haven’t been posting much on here just recently because I’ve been working on some larger projects instead of the smaller web-based stories.  These include new book projects and television shows.  I can’t say anything about them at the moment but stay tuned – it looks as though I can make the first big announcement soon!

The Maverick Meteorologist
I have a new feature article in BBC Focus’s April issue.
“Meet Piers Corbyn, the man who says he can out-forecast the Met Office’s supercomputers.  He’s won a tidy sum by placing bets on the weather but his radical ideas on forecasting have received a rather frosty reception from meteorologists.  Stuart Clark sheds some light on his unusual system.”

Book Depository Editor’s Choice: “Deep Space is awe-inspiring”
I have just been made aware that on 7 March, my latest book, Deep Space, was picked as ‘something for the weekend’ by Mark Thwaite, becoming the editor’s choice over at the book depository (www.bookdepository.co.uk), an on-line bookseller.
Mark says, “Deep Space is awe-inspiring – and by that I mean Deep Space the book is awe-inspiring!
Firstly, and not unlike real, actual space in this regard, Deep Space is big. Really big! The book's dimensions are 36.8 by 27.9 by 4.6cm. Take a moment to think about that and you'll realise this is a lovely chunky slab of a tome. And it needs to be: within are some of the most amazing photographs of deep space you'll ever see. … will delight anyone who has ever looked up at the stars at night and wondered what was up there.”

Is the dark matter mystery about to be solved?
New Scientist issue 2646
I share the cover story on this week’s New Scientist.  My article explores the nature of dark matter, whilst Amanda Gefter’s companion piece explores the nature of dark energy.  Here’s the introduction to the two articles:
     “As far as most of the universe is concerned, you're inconsequential. The everyday stuff that constitutes you and everything you care about makes up just 4 per cent of the cosmos; the rest we call dark matter and dark energy. What they actually are, though, is anyone's guess. Now we may be on the verge of enlightenment. In this article, we report how experiments are getting ready to identify dark matter, while on page 32 we consider why dark energy may be an illusion created by our place in space. Be prepared for a new cosmic order...”
     And here is the introduction to my article:
     “THIS YEAR, there's a good chance that a sizeable chunk of our universe will turn up. A fair bit of the cosmos - 22 per cent of it, in fact - seems to be made of invisible dark matter, whose extra gravity helps to bind stars together in galaxies, and galaxies together...”

Deep Space is published in the UK
My latest book, Deep Space, is published by Quercus and now available throughout the UK.
From the dust jacket:
“What are time and space? When and how did the universe begin – and how will it end? Why has such a rich variety of celestial objects come into being? And was life an inevitable development in the cosmos?
     The answers to our most profound questions lie in the depths of space. To look here is, in effect, to look back in time, because we see the light emitted long ago from distant stars and galaxies. As we stare deeper into space, we also gaze further into the past – back towards the beginning of the universe itself.
     Now Deep Space allows us to see, with our own eyes, the mysterious objects and phenomena that inhabit the far reaches of the cosmos and the earliest times of existence.
     Each of this book’s ten chapters explains one big idea in humanity’s study of the origins and evolution of the universe. These fundamental concepts include the big bang and the expanding universe; the formation of stars and planets; the anatomy and lifecycle of a galaxy; the existence of black holes and supermassive black holes; gravity and Einstein’s Theory of Relativity; dark matter and dark energy; the cosmic web of galaxies; and theories of how the universe will end.
     Clearly introduced by Dr. Stuart Clark’s straightforward commentary, these cornerstones in our understanding of the universe are exemplified by a multitude of stunning images and diagrams.
Within Deep Space are over 250 of the very latest and clearest images of the cosmos, provided by the Hubble Space Telescope and other, even more advanced, viewing technologies. These cosmic exotica include: spiral, elliptical, lenticular, ring and irregular galaxies; nebulae and supernova; white dwarfs; quasars; colliding galaxies; star formation and stellar nurseries; dying and exploding stars; planets and the solar system; the large-scale structure of the cosmos; and even images that give evidence of the great ‘invisibles’ of the universe – black holes, dark matter and dark energy.”

Mars and Venus are surprisingly similar
I have a new story published at ESA.
“Using two ESA spacecraft, planetary scientists are watching the atmospheres of Mars and Venus being stripped away into space. The simultaneous observations by Mars Express and Venus Express give scientists the data they need to investigate the evolution of the two planets’ atmospheres. …”
