These clouds are easily seen from Earth by optical telescopes. Conversely, the radio maps also show ammonia-poor air sinking down into the planet, opening holes in the cloud-cover similar to how descending air from upper layers dissipates clouds on Earth. The analysis revealed an active weather system in Jupiter’s upper atmosphere in which plumes of ammonia swell up in wave patterns to form bands tens of thousands of kilometres across. These bands are interspersed with vast cloudless regions, where dry air descends.

  • John Louis Emil Dreyer – a Short Biography Dr
    John Louis Emil Dreyer – A Short Biography Dr. Wolfgang Steinicke, FRAS The Danish astronomer Dreyer was the most influential cataloguer of nebulae and clusters in the 19th century.1 He is the creator of the famous New General Catalogue (NGC), published in 1888. He also made major historical contributions, especially about Tycho Brahe. Copenhagen Johan Ludvig Emil Dreyer (in English later: John Louis Emil) was born on 13 February 1852 in Copenhagen (Fig. 1). Many of his ancestors served in the army and navy. His father, Johan Christopher Friedrich Dreyer,2 became Danish Minister of War and the Navy in 1864. Also three of Dreyer’s sons kept this tradition, e.g. Frederic Charles Dreyer as Admiral of the Royal Navy. But the Dreyer with whom we are concerned obviously took a very different path, becoming an eminent astronomer. He attended school in Copenhagen and was initially interested in languages, history and science. At the age of 14 he got a book about Tycho Brahe, from which originated his lifetime fascination for the great Danish astronomer. Now his aim was to study astronomy. Dreyer often visited the new Copenhagen Observatory at Østervold; especially Schjellerup took care of the interested pupil. Even at that time, his talent for observations and precise analyses had already appeared. Fig. 1: John Louis Emil Dreyer (1852–1926) during his time in Armagh. In 1869, at the age of 17, Dreyer began his study of mathematics and astronomy at Copenhagen University. There he was particularly fascinated by the lectures of Heinrich Ludwig d’Arrest, director of the observatory.

  • Caroline Herschel: Discoverer of Comets Dr Sheila Kanani
    Caroline Herschel: Discoverer of Comets Dr Sheila Kanani 2 June 2021 In this talk Dr Sheila Kanani combines the story of a pioneering woman astronomer, with an account of the science behind comets, asteroids and meteors. Introduction Caroline Herschel began her life in astronomy supporting the work of her amateur astronomer brother William. She was working with him when he discovered the planet Uranus. She went on to become the world’s first professional woman astronomer, her salary provided by King George III of Great Britain. The catalogue of nebulae she produced brought her the Royal Astronomical Society’s 1828 Gold Medal – the first awarded to a woman, the next gold medal awarded to a woman wasn’t until 1996, and since then there still have only been a handful. Caroline discovered 8 comets, personally discovering five of those, and she also was the second person to discovered Comet Encke. Working as a team, William and Caroline Herschel increased the number of known nebulae from about 100 to 2,500. In this Cinderella story (where the prince is astronomy, not a man!) I will give you an account of Lina’s life, showing you what a pioneering woman she was, even back in the 1700s and 1800s when being female was far more of a penalty than a success, interwoven with the science behind the astronomy she was famous for. And during this talk there will be a short demonstration of a kitchen comet, using dry ice! Links to the RAS and Me I am the first to admit that Caroline was only introduced to me about 6 years ago, when I started my job at the Royal Astronomical Society in 2014, but she quickly became a firm favourite in my storytelling, a role model in astronomy and a formidable creature to look up to.

  • John Louis Emil Dreyer – Eine Kurze Biografie
    John Louis Emil Dreyer – Eine kurze Biografie Dr. Wolfgang Steinicke, FRAS Der dänische Astronom Dreyer war der einflussreichste Katalogisierer von Nebel und Sternhaufen im 19. Jahrhundert.1 Er schuf den bedeutenden New General Catalogue (NGC), publiziert 1888. Wir verdanken ihm auch wichtige historische Beiträge, wie etwa zu Tycho Brahe. Kopenhagen Johan Ludvig Emil Dreyer (im Englischen später John Louis Emil) wurde am 13. Februar 1852 in Kopen- hagen geboren (Abb. 1). Seine Vorfahren dienten in Armee und Marine. Der Vater, Johan Christopher Friedrich Dreyer2, wurde 1864 dänischer Kriegs- und Marineminister. Auch Dreyers drei Söhne folgten dieser Tradition, so war Frederic Charles Dreyer Admiral der Royal Navy. Dreyer selbst schlug mit seiner Laufbahn als Astronom deutlich aus der Reihe. Er ging in Kopenhagen zur Schule und interessierte sich bereits früh für Sprachen, Ge- schichte und Naturwissenschaften. Mit 14 erhielt er ein Buch über Tycho Brahe und war zeitlebens von dem großen dänischen Astronomen fasziniert. Er wollte Astronomie studieren und besuchte oft die neue Kopenhage- ner Sternwarte auf dem Østervold. Besonders Hans Carl Frederik Christian Schjellerup, zu dieser Zeit Observa- tor, kümmerte sich um den interessierten Schüler. Bereits hier zeigte sich seine Begabung für präzises Arbeiten. Abb. 1: John Louis Emil Dreyer (1852–1926) 1869, im Alter von 17, begann Dreyer das Studium der Mathematik und Astronomie an der Universität Kopenhagen. Besonders die Vorlesungen von Sternwartendirektor Heinrich Ludwig d’Arrest faszinierten ihn. Er blieb zeitlebens sein großes Vorbild und sein Einfluss ist vor allem in Dreyers Arbeiten über Nebel deutlich spürbar. Bereits nach einem Jahr durfte Dreyer die Instrumente des Observatoriums benutzen.

  • William Herschel's 'Hole in the Sky' and the Discovery Of
    Journal of Astronomical History and Heritage, 19(3), 305–326 (2016). WILLIAM HERSCHEL’S ‘HOLE IN THE SKY’ AND THE DISCOVERY OF DARK NEBULAE Wolfgang Steinicke Gottenheimerstr. 18, D-79224, Umkirch, Germany. E-mail: [email protected] Abstract: In 1785 William Herschel published a paper in the Philosophical Transactions containing the remarkable section ―An opening or hole‖. It describes an unusual vacant place in Scorpius. This matter falls into oblivion until Caroline Herschel initiated a correspondence with her nephew John in 1833. It contains Herschel‘s spectacular words ―Hier ist wahrhaftig ein Loch im Himmel― (―Here truly is a hole in the sky‖). About a hundred years later, Johann Georg Hagen, Director of the Vatican Observatory, presented a spectacular candidate for the ‗hole‘, discovered in 1857 by Angelo Secchi in Sagittarius and later catalogued by Edward E. Barnard as the dark nebula B 86. Hagen‘s claim initiated a debate, mainly in the Journal of the British Astronomical Association, about the identity of Herschel‘s ‗object‘. Though things could be partly cleared up, unjustified claims still remain. This is mainly due to the fact that original sources were not consulted. A comprehensive study of the curious ‗hole‘ is presented here. It covers major parts of the epochal astronomical work of William, Caroline and John Herschel. This includes a general study of ‗vacant places‘, found by William Herschel and others, and the speculations about their nature, eventually leading to the finding that dark nebulae are due to absorbing interstellar matter. Some of the ‗vacant places‘ could be identified in catalogues of dark nebulae and this leads to a ‗Herschel Catalogue of Dark Nebulae‘—the first historic catalogue of its kind.

  • The TYCHOS Unser Geoaxiales Binärsystem
    The TYCHOS Unser Geoaxiales Binärsystem von Simon Shack – 2018 Deutsche Übersetzung von Wini R. Schäfer Vorwort TYCHOS ist mein Vorschlag für ein kosmisches Modell. Es basiert auf modernen und altehrwürdigen astronomischen Beobachtungen, ist von ihnen inspiriert und baut auf ihnen auf. Insbesondere stützt sich meine Arbeit auf eine Reihe von weniger bekannten, übersehenen und/oder vernachlässigten Lehren aus der Zeit von 1500 bis 1800 (sowie aus der Antike) und erweitert diese. Ich widme diese Studie einigen brillanten Astronomen, deren Arbeit zu Gunsten der so genannten "kopernikanischen Revolution" übergangen wurde. Zu diesen frühen, aufschlussreichen Architekten, die den Grundstein für unser heutiges Modell des Sonnensystems legten, gehören Nilakantha Somayaji (Autor des Tantrasangraha, 1501), Samanta Candrasekhara Simha - (auch bekannt als. Pathani Samanta, 1835-1904), die alten Maya/Azteken/Sumerer/Griechen/Ägypter (u. a.) und natürlich Tycho Brahe (zusammen mit seinem treuen Helfer Longomontanus), dessen tadellose Beobachtungsdaten und -tabellen noch heute als die genauesten gelten, die je erstellt wurden. Seite 1 von 233 Trotz Brahes rigoroser und unwidersprochener Dokumentation wurde sein eigenes Modell des Sonnensystems schließlich von seinem Assistenten, dem berühmten Johannes Kepler, auf den Kopf gestellt. Kepler nutzte die Beobachtungen seines Meisters in seinen mühsamen Versuchen, sein diametral entgegengesetztes kopernikanisches Modell zu validieren. Wie nur wenige wissen, wurde Kepler schließlich (1988) entlarvt, weil er die wichtigen Beobachtungsdaten von Brahe (über den Mars) gefälscht hatte, um sie mit seiner heliozentrischen These in Einklang zu bringen. Sein Vermächtnis ist daher äußerst fragwürdig; Brahe hatte ihn ausdrücklich mit der Lösung des verwirrenden Verhaltens dieses besonderen Himmelskörpers betraut, und Keplers Gesetze der Planetenbewegung wurden fast ausschließlich (mathematisch) aus seinem unerbittlichen "Krieg gegen den Mars" (wie er es gerne nannte) abgeleitet.

    Cambridge University Press 978-0-521-19267-5 - Observing and Cataloguing Nebulae and Star Clusters: From Herschel to Dreyer’s New General Catalogue Wolfgang Steinicke Frontmatter More information Observing and Cataloguing Nebulae and Star Clusters From Herschel to Dreyer’s New General Catalogue The New General Catalogue, created in 1888, is the source for ref- erencing bright nebulae and star clusters, both in professional and amateur astronomy. With 7840 entries, it is the most-used histor- ical catalogue of observational astronomy, and NGC numbers are commonly referred to today. However, the fascinating history of the discovery, observation, description and cataloguing of nebu- lae and star clusters in the nineteenth century has largely gone untold, until now. This well-researched book is the first comprehensive histori- cal study of the NGC, and is an important resource to all those with an interest in the history of modern astronomy and visual deep-sky observing. It covers the people, observatories, instru- ments and methods involved in nineteenth-century visual deep- sky observing, as well as prominent deep-sky objects. The book also compares the NGC with modern object data, demonstrating how important the NGC is in observational astronomy today. Dr WOLFGANG STEINICKE, FRAS, is a committee member of the Webb Deep-Sky Society and Director of its Nebulae and Clusters section, a core team member of the international NGC/ IC Project, Head of the History Section of the VdS, Germany’s largest national association of amateur astronomers, and a mem- ber of the Working Group for the History of Astronomy of the Astronomische Gesellschaft.
