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. -

Facts & Statistics About the Project
1 Hubble’s 15th Anniversary – Facts about the ESA project Introduction 24 April 2005 marked the 15th anniversary of the launch of the NASA/ESA Hubble Space Telescope. As an observatory in space, Hubble is a major project that has made an enormous impact both in terms of scientific output and in its immediate public appeal. Hubble has exploited its unique scientific capabilities in regions where no other instruments can compete. The telescope consistently delivers super-sharp images and clean, uncontaminated spectra over the entire near-infrared to ultraviolet regions of the electromagnetic spectrum. This has opened up new scientific territory and has resulted in many paradigm-breaking discoveries. Exquisite quality images have enabled astronomers to gain entirely new insights into the workings of a huge range of different astronomical objects. Hubble has provided a visual overview of the underlying astrophysical processes taking place in these objects, ranging from planets in our Solar System to galaxies in the young Universe. The renowned British astronomer Malcolm Longair writes in the preface to ESA’s anniversary book: ”The Hubble Space Telescope has undoubtedly had a greater public impact than any other space astronomy mission ever. The images included in this beautiful volume are quite staggering in the detail they reveal about the Universe we live in and have already become part of our common scientific and cultural heritage.” The project Many people agree that the long-term well-being and cultural development of European citizens depends on research and technological development. Information about science and scientists is a vital component of the scientific process, but the competition for attention in today’s mass-media market is fierce. -

The cluster is shown slightly right of center near the bottom of the chart, along with other nearby stars that we will use in this month's hunt: • Pollux • • • • • • Gamma M44 • Cancer. • • ~ • ;.

Procyon is the 8th brightest star in the sky, and quite close to us, at a distance of only 11~ light years. It was named Procyon, meaning "Before the Dog," because it rises just before Sirius, The Dog Star: that was important because Sirius heralded the annual flooding of the Nile River, which was crucial to the life of ancient Egypt. Just over 4° NW of Procyon is mag 2.9 blue dwarf Beta Canis Minoris, which forms a pretty lYz ° binocular group with a mag 4.3 orange giant and a mag 5.0 yellow giant. -

Progress in Rendering and Modeling for Digital Planetariums
EUROGRAPHICS 2010/ M. Cooper and K. Pulli Areas Paper Progress in Rendering and Modeling for Digital Planetariums M. Magnor1,2† and P. Sen2 and J. Kniss2 and E.Angel2 and S. Wenger1 1 TU Braunschweig, Germany 2 University of New Mexico, USA Abstract Contemporary challenges in the production of digital planetarium shows include real-time rendering realism as well as the creation of authentic content. While interactive, live performance is a standard feature of professional digital-dome planetarium software today, support for physically correct rendering of astrophysical phenomena is still often limited. Similarly, the tools currently available for planetarium show production do not offer much assistance towards creating scientifically accurate models of astronomical objects. Our paper presents recent results from computer graphics research, offering solutions to contemporary challenges in digital planetarium rendering and modeling. Incorporating these algorithms into the next generation of dome display software and production tools will help advance digital planetariums toward make full use of their potential. Categories and Subject Descriptors (according to ACM CCS): I.3.3 [Computer Graphics]: Picture/Image Generation—Viewing algorithms I.3.5 [Computer Graphics]: Computational Geometry and Object Modeling— Physically based modeling I.3.8 [Computer Graphics]: Applications—Digital Planetariums J.2 [Computer Appli- cations]: Physical Sciences and Engineering—Astronomy 1.
