Lomonosov, the Discovery of Venus's Atmosphere, and Eighteenth Century Transits of Venus
Journal of Astronomical History and Heritage, 15(1), 3-14 (2012). LOMONOSOV, THE DISCOVERY OF VENUS'S ATMOSPHERE, AND EIGHTEENTH CENTURY TRANSITS OF VENUS Jay M. Pasachoff Hopkins Observatory, Williams College, Williamstown, Mass. 01267, USA. E-mail: [email protected] and William Sheehan 2105 SE 6th Avenue, Willmar, Minnesota 56201, USA. E-mail: [email protected] Abstract: The discovery of Venus's atmosphere has been widely attributed to the Russian academician M.V. Lomonosov from his observations of the 1761 transit of Venus from St. Petersburg. Other observers at the time also made observations that have been ascribed to the effects of the atmosphere of Venus. Though Venus does have an atmosphere one hundred times denser than the Earth’s and refracts sunlight so as to produce an ‘aureole’ around the planet’s disk when it is ingressing and egressing the solar limb, many eighteenth century observers also upheld the doctrine of cosmic pluralism: believing that the planets were inhabited, they had a preconceived bias for believing that the other planets must have atmospheres. A careful re-examination of several of the most important accounts of eighteenth century observers and comparisons with the observations of the nineteenth century and 2004 transits shows that Lomonosov inferred the existence of Venus’s atmosphere from observations related to the ‘black drop’, which has nothing to do with the atmosphere of Venus. Several observers of the eighteenth-century transits, includ- ing Chappe d’Auteroche, Bergman, and Wargentin in 1761 and Wales, Dymond, and Rittenhouse in 1769, may have made bona fide observations of the aureole produced by the atmosphere of Venus. -

ASTRONOMY & ASTROPHYSICS (Div III) Chair: Professor Jay Pasachoff Marek Demianski, Visiting Professor of Astronomy Kevin Flaherty, Lecturer in Astronomy and Observatory Supervisor; affiliated with: Physics Department Anne Jaskot, Assistant Professor of Astronomy and Associate of the Hopkins Observatory; affiliated with: Physics Department; on leave Fall 2021 Jay M. Pasachoff, Chair and Field Memorial Professor of Astronomy, Director of the Hopkins Observatory How long will the Sun shine? How do we discover Earth-like planets among the many exoplanets circling other stars? How did the universe begin and how has it evolved over its 13.8-billion-year history? How do we detect not only light but also gravitational waves from afar? Astronomy is the science that asks and tries to answer questions like these. We have come a long way toward understanding what makes the sky appear as it does and how the Universe behaves. The Astronomy Department offers courses for anyone who is interested in learning about the Universe, and who would like to be able to follow new astronomical discoveries as they are made. All courses in Astronomy satisfy the Division III requirement. The Astronomy major and the Astrophysics major (administered jointly with the Physics Department) are described below. The beginning astronomy courses are offered on two levels. Astronomy 101, 102, 104, and 330-range courses are intended primarily for non-science majors and have no prerequisite. Astronomy 111 is designed for students with some exposure to physics. It has a prerequisite of one year of high school physics or permission of the instructor, and a co-requisite of Mathematics 140 or equivalent background in calculus. -
Main Objective: Scientific Justification: Proposer Name: Jay Pasachoff
Timestamp: 3/29/2016 16:46:02 Title of Proposed Observation: Observations of Transit of Mercury (ToM) 2016 May 9 Main Objective: Mercury will transit the Sun on 2016 May 9. We would like to use Hinode to observe the event with SOT, XRT, and EIS. The next opportunity will not be until the transit of November 2019. This HOP defines the overall plan for Hinode observations of this Transit of Mercury (ToM). Details of the observation schedule will have to be put together by the planning team after the Hinode observation and orbit timings are better defined (e.g., twilight and/or night timings). Scientific Justification: Our observational objectives are multi-fold: (a) We will study the black drop effect in white-light with SOT during contacts I and IV. A convincing explanation for this long-observed effect has been presented only recently (e.g., Schneider et al. 2004, Pasachoff et al. 2011). We will seek to gain further insight into the phenomenon with SOT images. (b) Image in Ca II as Mercury crosses spicules (or a prominence) at the limb; this could be useful, e.g., characterizing spicule widths. (c) Use SOT/NFI observations in the Na D1 line, to attempt to image exospheric absorption. (d) Polarization measurements with SOT/SP to characterize the polarization state of the instrumental scattered light. (e) Observations from XRT to observe Mercury silhouetted against the coronal background before, during, and after the transit. (f) The above SOT and XRT images, and also EIS slot images can be taken for public outreach and media releases. -

A Federal Agency Catalogue Designed by David Berreth Printed by The Brunswick Publishing Co. Brunswick, Maine FOREWORD This catalogue and the exhibition Nineteenth Century American Paintings at Bowdoin College begin a new chapter in the development of the Bow- doin College Museum of Art. For many years, the Colonial and Federal portraits have hung in the Bowdoin Gallery as a permanent exhibition. It is now time to recognize that nineteenth century American art has come into its own. Thus, the Walker Gallery, named in honor of the donor of the Museum building in 1892, will house the permanent exhi- bition of nineteenth century American art; a fitting tribute to the Misses Walker, whose collection forms the basis of the nineteenth century works at the College. When renovations are complete, the Bowdoin and Boyd Galleries will be refurbished to house permanent installations similar to the Walker Gal- lery's. During the renovations, the nineteenth century collection will tour in various other museiniis before it takes its permanent home. My special thanks and congratulations go to David S. Berreth, who developed the original idea for the exhibition to its present conclusion. His talent for exhibition installation and ability to organize catalogue materials will be apparent to all. -
