COMPETENCES : ● Utilisation du théorème de Pythagore ● Utilisation de Google Earth pour évaluer des distances à vol d'oiseau ● Recherche personnelle de données REALISATION : Il s'agit ici de mettre en application le théorème de Pythagore mais avec une vision terrestre dans un premier temps suite à un questionnement de l'élève puis dans un second temps de réutiliser la même démarche dans le cadre spatial de la visibilité d'un satellite. Fiche élève ____________________________________________________________________________ 1. Victor Hugo a écrit dans Les Châtiments : "Les horizons aux horizons succèdent […] : on avance toujours, on n’arrive jamais ". Face à la mer, vous voyez l'horizon à perte de vue. Mais "est-ce loin, l'horizon ?". D'après toi, jusqu'à quelle distance peux-tu voir si le temps est clair ? Réponse 1 : " Sans instrument, je peux voir jusqu'à .................. km " Réponse 2 : " Avec une paire de jumelles, je peux voir jusqu'à ............... km " 2. Nous allons maintenant calculer à l'aide du théorème de Pythagore la ligne d'horizon pour une hauteur H donnée.

  • 02 Southern Cross
    Asterism Southern Cross The Southern Cross is located in the constellation Crux, the smallest of the 88 constellations. It is one of the most distinctive. With the four stars Mimosa BeCrux, Ga Crux, A Crux and Delta Crucis, forming the arms of the cross. The Southern Cross was also used as a remarkably accurate timepiece by all the people of the southern hemisphere, referred to as the ‘Southern Celestial Clock’ by the portuguese naturalist Cristoval D’Acosta. It is perpendicular as it passes the meridian, and the exact time can thus be calculated visually from its angle. The german explorer Baron Alexander von Humboldt, sailing across the southern oceans in 1799, wrote: “It is a timepiece, which advances very regularly nearly 4 minutes a day, and no other group of stars affords to the naked eye an observation of time so easily made”. Asterism - An asterism is a distinctive pattern of stars or a distinctive group of stars in the sky. Constellation - A grouping of stars that make an imaginary picture in the sky. There are 88 constellations.

  • A Joint ESA-CONSTELLATION Workshop on the Formation of Brown Dwarfs
    -ESA- Space Science Faculty Courtesy NASA/JPL-Caltech CONSTELLATION is a European Commission Sixth Framework Marie Curie Research Training Network (contract number MRTN-CT-2006-035890) A joint ESA-CONSTELLATION workshop on the formation of brown dwarfs Contact info: [email protected]! www.rssd.esa.int/BD2009 Gemini Observatory/AURA WORKSHOP Recipes for making brownies: theory vs. observations Scientific Rationale: The origin of Brown Dwarfs (BDs) is an important component of the theory of star formation. Recent ground based and satellite observations are revealing an increasing number of BDs; however, their origin remains somewhat mysterious as their mass is 2 orders of magnitude below the average Jeans mass in star-forming clouds. Explaining why they are so common thus requires detailed understanding of the fragmentation processes during star formation, as well as exploring other formation scenarios. This workshop will focus on recent theoretical and observational progresses in the field of BD formation as well as explore current and future perspectives. Our purpose is to bring together the leading experts working in this field, foster new collabora- tions and, in particular, promote extended interactions among young PhD/post-doc researchers. SOC: L.

  • Proto-Micronesian Reconstructions—1
    Proto-Micronesian Reconstructions—1 Byron W. Bender, Ward H. Goodenough, Frederick H. Jackson, Jeffrey C. Marck, Kenneth L. Rehg, Ho-min Sohn, Stephen Trussel, and Judith W. Wang1 university of hawai‘i and university of pennsylvania Part 1 presents some 980 reconstructions for Proto-Micronesian, Proto–Central Micronesian, and Proto–Western Micronesian. Part 2 (to appear in volume 42 [2]) gives reconstructions for two additional subgroups within Proto-Micronesian: Proto-Pohnpeic and Proto-Chuukic, and their immediate ancestor, Proto– Pohnpeic-Chuukic. A handful of putative loans are also identi²ed, and a single English ²nder list is provided for all of the reconstructions. INTRODUCTION. Lexical data for a number of Micronesian languages began to be collected systematically in the mid-1960s as part of the development of language lessons for the U.S. Peace Corps and in connection with other Micronesian language projects that followed at the University of Hawai‘i. These data were stored on a main- frame computer using programs then being developed (Hsu and Peters 1984), and eventually dictionaries were published for a number of the languages included in this study (Elbert 1972, Abo et al. 1976, Lee 1976, Sohn and Tawerilmang 1976, Harrison and Albert 1977, Jensen 1977, Rehg and Sohl 1979, Goodenough and Sugita 1980, Jackson and Mark 1991). Comparative work using these data began with Marck 1977, focusing on the group of languages referred to as Nuclear Micronesian. In the next several years, the authors of the current study put the initial data on computer and sub- stantially added to them by directly eliciting information from speakers of Microne- sian languages who were students in the Bilingual Education Project for Micronesia at the University of Hawai‘i.

  • A Statistically Significant Lack of Debris Discs in Medium Separation Binary Systems
    MNRAS 000,1{21 (2019) Preprint 12 July 2019 Compiled using MNRAS LATEX style file v3.0 A statistically significant lack of debris discs in medium separation binary systems Ben Yelverton1?, Grant M.

Received YYY; in original form ZZZ ABSTRACT We compile a sample of 341 binary and multiple star systems with the aim of searching for and characterising Kuiper belt-like debris discs. The sample is as- sembled by combining several smaller samples studied in previously published work with targets from two unpublished Herschel surveys. We find that 38 sys- tems show excess emission at 70 or 100 µm suggestive of a debris disc. While nine of the discs appear to be unstable to perturbations from their host binary based on a simple analysis of their inferred radii, we argue that the evidence for genuine instability is not strong, primarily because of uncertainty in the true disc radii, uncertainty in the boundaries of the unstable regions, and orbital projec- tion effects. The binary separation distributions of the disc-bearing and disc-free systems are different at a confidence level of 99:4%, indicating that binary sep- aration strongly influences the presence of detectable levels of debris.

    August First Light Newsletter 1 message August, 2014 Issue 122 AlachuaAstronomyClub.org North Central Florida's Amateur Astronomy Club Serving Alachua County since 1987 BREAKING NEWS -- ROSETTA HAS JUST ARRIVED AT COMET 67/P Member Member Astronomical League Initiated in late 1993 by Europe and the USA, and launched in 2004, the International Rosetta Mission is an historic first: Send a spacecraft to chase and orbit a comet, ride along as the comet plunges sun ward to learn how a frozen comet transforms by the Sun's warmth, and dispatch a controlled lander to make in situ measurements and make first images Member from a comet's surface. NASA Night Sky Network Ten years later Rosetta has now arrived at Comet 67P/Churyumov- Gerasimenko and just successfully made orbit today, 2014 August 6! Unfortunately, global events have foreshadowed this memorable event and news media have largely ignored this impressive space mission. AAC Member photo: The Rosetta comet mission may be the beginning of a story that will tell more about us -- both about our origins and evolution. (Hence, its name "rosetta" for the black basalt stone with inscriptions giving the first clues to deciphering Egyptian hieroglyphics.) Pictures received over past weeks are remarkable with the latest in the past 24 hours showing awesome and incredible detail including views that show the comet is a connected binary object rotating as a unit in 12 hours. Anyone see the glorious pairing of Venus and Jupiter this morning (2016 Aug. 18)? For images see http://www.esa.int/ spaceinimages/Missions/ Except when Mars is occasionally brighter Rosetta than Jupiter, these two planets are the brightest nighttime sky objects (discounting Example Image (Aug.
