The significance of that night marked one of the truly great turning points in the development of astronomical techniques: Dr Henry Draper, a wealthy New York medical doctor, had secured the first photograph of a nebula: a 51-minute exposure on a dry gelatinobromide plate showing the wispy nebulosity of the Orion Nebula. By March 1882, Draper had secured an exposure of 137 minutes, showing far richer detail of both bright and dark features. The rest is histapy. The photographic era heralded in a universe where hints of the presence of cosmic dust were strongly alluded to: from star-forming regions such as Messier 17, to the Horsehead Nebula in Orion, to the striking dark finger in the Cone Nebula, to the magnificent dark bands in the plane of our Milky Way. Historically, astromomers from the very beginning have been afraid of dust.","brand":"WoB","offers":[{"title":"- \/ - \/ INTERNAL","offer_id":52350866260241,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ NEW \/ INGRAM","offer_id":52350869963025,"sku":"NLS9789401066372","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9789401066372.jpg?v=1758180556"},{"product_id":"penetrating-bars-through-masks-of-cosmic-dust-book-david-l-block-9789401570855","title":"Penetrating Bars through Masks of Cosmic Dust","description":"THE EDITORS: DAVID L.

This year, 2010, is thus a special year for scientists worldwide: it celebrates the 350th anniversary of the founding of the Royal Society, whose current President is Martin Rees. One of the enormous challenges facing scientists in the 1600s was the great need fortheclassi cationofobjectstheywerestudying,particularlyinthe eldofbotany. The seeds for classi cation lie in the works of the British naturalist John Ray (1628-1705), who commencing in 1660 with hisCatalogusplantarumcirca Cantabrigiamnascentium (Catalogue of Cambridge Plants) - published in the year in which the Royal Society was founded - and ending with the posthumous publi- tion ofSynopsisMethodicaAviumetPiscium in 1713, pioneered systematic studies on plants, birds, mammals, sh, and insects.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52430861566225,"sku":"NLS9781441973160","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ NEW \/ INGRAM","offer_id":53518950760721,"sku":"NIN9781441973160","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9781441973160.jpg?v=1759170886"},{"product_id":"galaxies-and-their-masks-book-david-l-block-9781493939701","title":"Galaxies and their Masks","description":"Various kinds of masks obscure our view of our galaxy, the Milky Way, as well as of other galaxies. Masks of interstellar dust affect our measurements within galaxies, on scales ranging from individual supernovae to the galaxies themselves. The mass mask (our inability to image mass rather than light) gives astronomers a very incomplete picture of the size and structure of galaxies themselves, because we cannot image the dark matter which provides most of the galactic mass. Another mass is the dynamical mask as galaxies form, much dynamical information is lost in the birthing process. A new thrust in research is to retrieve such information by means of chemical tagging. About 50 astronomers flew into Namibia in April 2010, to celebrate the 70th birthday of Professor K.C. Freeman, Fellow of the Royal Society. At age 70, Freeman, a father of dark matter in galaxies, continues to be one of planet's most highly cited astronomers. The current volume affords readers a unique perspective on galaxies by probing the thoughts of some of the greatest astronomers of our age. Contributions focus on galaxies from within our Local Group to those in our high redshift Universe. Approximately 40 in-depth review and contributed papers are contained in the volume, each written by an expert in the field. Two unusual features of the current volume include the Star Country of the San people of southern Africa as well as the introduction into astronomy of The Treachery of Images by the Belgian surrealist artist René Magritte. Everything we see hides another thing, we always want to see what is hidden by what we see, said Magritte. These words resonate the theme of the current volume Galaxies and their Masks, which is written at a level to be appreciated by both specialist and doctoral student alike.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52588470796561,"sku":"NLS9781493939701","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9781493939701.jpg?v=1761058168"},{"product_id":"penetrating-bars-through-masks-of-cosmic-dust-book-david-l-block-9781402028618","title":"Penetrating Bars through Masks of Cosmic Dust","description":"THE EDITORS: DAVID L.
