The image was acquired using a 16-inch RCOS telescope at f/8.9 from Sierra Remote Observatories in California. Exposure was a total of 10.9 hours in LRGB using an Apogee U16M camera. In their words: “The goal in processing this target was to reveal the intricate inner structures and accentuate some of the more subtle colour shades not often seen, but nonetheless there.” June / juin 2011 JRASC | Promoting Astronomy In Canada 93 President’s Corner Mary Lou Whitehorne The Journal is a bi-monthly publication of The Royal Astronomical Society of Canada and is President, RASC devoted to the advancement of astronomy and allied sciences.

  • Martian Crater Morphology
    ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter.

  • Hubble Revisits the Veil Nebula 2 April 2021
    Image: Hubble revisits the Veil Nebula 2 April 2021 this stellar violence, the shockwaves and debris from the supernova sculpted the Veil Nebula's delicate tracery of ionized gas—creating a scene of surprising astronomical beauty. The Veil Nebula is also featured in Hubble's Caldwell Catalog, a collection of astronomical objects that have been imaged by Hubble and are visible to amateur astronomers in the night sky. Provided by NASA Credit: ESA/Hubble & NASA, Z. Levay This image taken by the NASA/ESA Hubble Space Telescope revisits the Veil Nebula, which was featured in a previous Hubble image release. In this image, new processing techniques have been applied, bringing out fine details of the nebula's delicate threads and filaments of ionized gas. To create this colorful image, observations were taken by Hubble's Wide Field Camera 3 instrument using five different filters. The new post-processing methods have further enhanced details of emissions from doubly ionized oxygen (seen here in blues), ionized hydrogen, and ionized nitrogen (seen here in reds). The Veil Nebula lies around 2,100 light-years from Earth in the constellation of Cygnus (the Swan), making it a relatively close neighbor in astronomical terms. Only a small portion of the nebula was captured in this image. The Veil Nebula is the visible portion of the nearby Cygnus Loop, a supernova remnant formed roughly 10,000 years ago by the death of a massive star. That star—which was 20 times the mass of the Sun—lived fast and died young, ending its life in a cataclysmic release of energy.

  • 1 Reading Athenaios' Epigraphical Hymn to Apollo: Critical Edition And
    Reading Athenaios’ Epigraphical Hymn to Apollo: Critical Edition and Commentaries DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Corey M. Hackworth Graduate Program in Greek and Latin The Ohio State University 2015 Dissertation Committee: Fritz Graf, Advisor Benjamin Acosta-Hughes Carolina López-Ruiz 1 Copyright by Corey M. Hackworth 2015 2 Abstract This dissertation is a study of the Epigraphical Hymn to Apollo that was found at Delphi in 1893, and since attributed to Athenaios. It is believed to have been performed as part of the Athenian Pythaïdes festival in the year 128/7 BCE. After a brief introduction to the hymn, I provide a survey and history of the most important editions of the text. I offer a new critical edition equipped with a detailed apparatus. This is followed by an extended epigraphical commentary which aims to describe the history of, and arguments for and and against, readings of the text as well as proposed supplements and restorations. The guiding principle of this edition is a conservative one—to indicate where there is uncertainty, and to avoid relying on other, similar, texts as a resource for textual restoration. A commentary follows, which traces word usage and history, in an attempt to explore how an audience might have responded to the various choices of vocabulary employed throughout the text. Emphasis is placed on Athenaios’ predilection to utilize new words, as well as words that are non-traditional for Apolline narrative. The commentary considers what role prior word usage (texts) may have played as intertexts, or sources of poetic resonance in the ears of an audience.

I found that out when I went to Criterion Optical Co. in Hartford with a very small budget for a telescope, and the nice person I talked with finally reached into a drawer and pulled out a slightly scratched small mirror and offered it to me cheap, along STAR with a slightly defective focuser (no knob or rack, but it did have a small diagonal attached), and some miscellaneous small lenses and cardboard spacers for making an eyepiece. He also gave me FIELDS some brief verbal instructions on how to put all this together into a Newtonian telescope. Next stop the hardware store to buy a piece of stove pipe, and I was in business after a little construction work. There were no astronomy books in our local Newsletter of the library, but just sweeping the dark sky (back then it was dark) and Amateur Telescope Makers of Boston picking out some interesting sights – even with no idea what they Including the Bond Astronomical Club were or what they were called - was a thrill for a teenager.

  • Appendix I Lunar and Martian Nomenclature
    APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject. For further references see: [AU Trans. X, 259-263, 1960; XIB, 236-238, 1962; Xlffi, 203-204, 1966; xnffi, 99-105, 1968; XIVB, 63, 129, 139, 1971; Space Sci. Rev. 12, 136-186, 1971. Because at the recent General Assemblies some small changes, or corrections, were made, the complete list of Lunar and Martian Topographic Features is published here.
