A physicist and an inventor, Jules Janssen (1824-1907) devoted his life to astronomical research. He spent many years traveling around the world to observe total Solar eclipses, demonstrating that a new era of science had just come thanks to the use of both spectroscopy and photography, and persuading the French Government of the necessity of founding a new observatory near Paris. He became its director in 1875. There, at Meudon, he began routine photographic recordings of the Sun surface and had a big refractor and a big reflector built. Meanwhile, he also succeeded in building an Observatory at the summit of Mont-Blanc. The story of this untiring and stubborn globe-trotter is enriched by extracts of the unpublished correspondence with his wife. One can thus understand why Henriette often complained of the solitude in which she was left by her peripatetic husband: “There are men who leave their wives for mistresses; you do it for journeys!” ... Basking in the glow of his success, Janssen was able to undertake the construction of the great astrophysical observatory of which he had dreamed. It was at Meudon that he had it built.

What if one of the most thrilling stories in the history of science turned out to be wrong? Can urban legends creep into the hallowed grounds of scientific history? As incredible as it may sound, the story of one of the most important elements in modern times – helium - has been often misrepresented in books, encyclopedias, and online sources, despite the fact that archival materials tell a different story. Open the entry for Helium in any encyclopaedia and you will read a false story that has been repeated over the years. ‘Encyclopaedia Britannica’, for example, says that helium was discovered by the French astronomer Pierre Janssen while observing a total solar eclipse from India in 1868. Apparently he noticed something new in the spectrum of the sun, which he thought was the signature of an undiscovered element. The truth is that Janssen never saw any sign of a new element during his observations in India. His reports and letters do not mention any such claim. Other sources would have you believe that helium was jointly discovered by Janssen and Norman Lockyer, a British scientist, and that their discovery letters reached Paris the same day, one sent from India, and the other from England. Again, the truth is completely different. Two letters from Lockyer and Janssen did reach Paris the same day in 1868, but their letters did not mention any new element. What they had discovered was a new way of observing the Sun without a solar eclipse. This would ultimately lead to the discovery of helium, in which Lockyer would play a prominent role, but not Janssen. At the same time, Norman Robert Pogson, a disgruntled British astronomer stationed in India did notice something peculiar during the eclipse. He was the first one to notice something odd about the spectrum of the Sun that day, and his observations would prove crucial to Lockyer’s own investigations of helium. But Pogson’s report was never published in any peer reviewed journal and it languished on the desk of a local British officer in colonial India. This book tells the real story behind the discovery of helium, along with biographical sketches of the scientists and descriptions of the milieu in which they worked. It will convey the excitement, confusion, and passion of nineteenth century scientists, using their own words, from their letters and reports. “The Story of Helium and the Birth of Astrophysics” chronicles one of the most exciting discoveries ever made and explains why it also marked the birth of a new branch of science called ‘astrophysics.’

The large telescope at Meudon has become legendary. When it was conceived, after 1870, astronomy as a whole was limited to visual observation. Knowledge of the sky was limited to what one could see, assisted only by optical means. The large telescopes produced at this time produced larger images, permitting close-up views: the Meudon telescope was able to accomplish this perfectly. At Meudon, which became the Mecca of visual observation, the major planets were examined in a way that no other telescope had previously been able to. The telescope monitored the state of their atmospheres and mapped the appearance of their surfaces. Through the telescope, one could obtain photographs showing the nuclei of comets, revealing their very small size, and by using an eyepiece one could measure the separation of double stars. With a marvellous little instrument, the polarimeter, the nature of clouds in planetary atmospheres has been determined, and the type of surface material identified. Many more results were obtained, while photography, universally adopted, revolutionized other knowledge about the world. The sensitive emulsion, combined with large aperture reflecting telescopes, revealed the deepness and richness of the cosmos. The vast telescope of Meudon, which was the largest refracting telescope in Europe, became a legendary instrument and was symbolic of a new way to practice astronomy. Audouin Dollfus, a renowned astronomer, describes the great years of the Meudon telescope. He gives us the entire story of this instrument, from the birth of the concept that drove Jules Janssen at the end of the nineteenth century, to the idea that French astronomy could provide an outstanding telescope which would approach the limits of technical and industrial resources. The telescope remained unchanged until 2006, when the first steps toward restoration and public reopening were taken.

In the late fifteenth century, clocks acquired minute hands. A century later, second hands appeared. But it wasn’t until the 1850s that instruments could recognize a tenth of a second, and, once they did, the impact on modern science and society was profound. Revealing the history behind this infinitesimal interval, A Tenth of a Second sheds new light on modernity and illuminates the work of important thinkers of the last two centuries. Tracing debates about the nature of time, causality, and free will, as well as the introduction of modern technologies—telegraphy, photography, cinematography—Jimena Canales locates the reverberations of this “perceptual moment” throughout culture. Once scientists associated the tenth of a second with the speed of thought, they developed reaction time experiments with lasting implications for experimental psychology, physiology, and optics. Astronomers and physicists struggled to control the profound consequences of results that were a tenth of a second off. And references to the interval were part of a general inquiry into time, consciousness, and sensory experience that involved rethinking the contributions of Descartes and Kant. Considering its impact on much longer time periods and featuring appearances by Henri Bergson, Walter Benjamin, and Albert Einstein, among others, A Tenth of a Second is ultimately an important contribution to history and a novel perspective on modernity.

'Catchers of the Light' is a History of Astrophotography. It tells the true stories of the 46 pioneers who did most to master the art of celestial photography, as it was known during its early days; and whose efforts have made it possible for us to see the many magnificent pictures of the Universe featured in books, magazines and on the internet. In its TWO magnificent volumes is contained an unbelievable collection of tales of adventure, adversity and ultimate triumph and tells the uplifting stories of this small band of ordinary men and women, who did such extraordinary things; overcoming obstacles as diverse as war, poverty, cholera, death, very unfriendly cannibal natives and even exploding donkeys. It has been written with a no specific audience in mind - it is a book for anybody in fact - astronomers, photographers, historians, genealogists, art dealers, students, artists, doctors, farmers, builders, teachers & many more. If you like to read about the lives of special people - those who never give up - no matter what - and who succeed in achieving the seemingly impossible - then this is the book for you. This book of 1600 or so pages, with 1800 or more photographs/illustrations and over 2000 references/notes - represents the FIRST fully detailed and professionally researched book on the subject; and tells of the incredible lives of the pioneers of Astrophotography, each with their own incredible story to tell - they were the ‘Catchers of the Light’. Catchers of the Light is divided into ten Parts (I-X), each covering a specific aspect of the subject- I: Origins of Astrophotography; II: Lunar Astrophotography; III: Solar Astrophotography; IV: Solar System Astrophography; V: Deep Space Astrophotography; VI: Photographic Astronomical Spectroscopy; VII: Photographic Sky Surveys; VIII: Astrographs; IX: Modern Digital Age; X: Appendices.
