Atelier disciplinaire AD 5 Mathématiques et Espace Anne-Cécile DHERS, Education Nationale (mathématiques) Peggy THILLET, Education Nationale (mathématiques) Yann BARSAMIAN, Education Nationale (mathématiques) Olivier BONNETON, Sciences - U (mathématiques) Cahier d'activités Activité 1 : L'HORIZON TERRESTRE ET SPATIAL Activité 2 : DENOMBREMENT D'ETOILES DANS LE CIEL ET L'UNIVERS Activité 3 : D'HIPPARCOS A BENFORD Activité 4 : OBSERVATION STATISTIQUE DES CRATERES LUNAIRES Activité 5 : DIAMETRE DES CRATERES D'IMPACT Activité 6 : LOI DE TITIUS-BODE Activité 7 : MODELISER UNE CONSTELLATION EN 3D Crédits photo : NASA / CNES L'HORIZON TERRESTRE ET SPATIAL (3 ème / 2 nde ) __________________________________________________ OBJECTIF : Détermination de la ligne d'horizon à une altitude donnée. 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. -

It consists of a humorous 24-minute show and educator’s package. The Orion Educator’s Guide is designed for Planetarians, Teachers, and parents. The information is researched, organized, and laid out so that the educator need not spend hours coming up with lesson plans or labs. This has already been accomplished by certified educators. The guide is written to alleviate the fear of space and the night sky (that many elementary and middle school teachers have) when it comes to that section of the science lesson plan. It is an excellent tool that allows the parents to be a part of the learning experience. The guide is devised in such a way that there are plenty of visuals to assist the educator and student in finding the Winter constellations. -

Stars and Their Spectra: an Introduction to the Spectral Sequence Second Edition James B
Cambridge University Press 978-0-521-89954-3 - Stars and Their Spectra: An Introduction to the Spectral Sequence Second Edition James B. Kaler Index More information Star index Stars are arranged by the Latin genitive of their constellation of residence, with other star names interspersed alphabetically. Within a constellation, Bayer Greek letters are given first, followed by Roman letters, Flamsteed numbers, variable stars arranged in traditional order (see Section 1.11), and then other names that take on genitive form. Stellar spectra are indicated by an asterisk. The best-known proper names have priority over their Greek-letter names. Spectra of the Sun and of nebulae are included as well.

Divinus Lux Observatory: Report #17
Vol. 5 No. 2 Spring 2009 Journal of Double Star Observations Page 94 Divinus Lux Observatory: Report #17 Dave Arnold Program Manager for Double Star Research 2728 North Fox Run Drive Flagstaff, AZ 86004 E-Mail: [email protected] Abstract: This report contains theta/rho measurements from 86 different double star systems. The time period spans from 2008.724 to 2008.967. Measurements were obtained using a 20-cm Schmidt- Cassegrain telescope and an illuminated reticle micrometer. This report represents a portion of the work that is currently being conducted in double star astronomy at Divinus Lux Observatory in Flagstaff, Arizona. Recently, an article came to my attention that was determined also fall into this period range of 10 to 500 submitted by Helmut Abt to the 240th symposium of years. This might imply that if the data base was the International Astronomical Union in August 2006. larger for the other listed period ranges, a similar This report entitled, “Observed Orbital Eccentricities,” pattern for the eccentricity value could also possibly discussed the well-known phenomenon that the orbits emerge. of binary star systems with periods of less than a few Secondly, a result that might appear surprising days have been circularized, or have eccentricities to some is that highly eccentric orbits (.8 - .99) are just near zero, because of tidal interaction between the as likely to appear in this data base as those that are components. Abt then goes on to state that for longer more circular (.0 - .2). Even in the categories that periods, the eccentricities of binaries with known represent the shorter periods, high eccentricity is orbital elements show a random distribution. -
Binocular Challenges
This page intentionally left blank Cosmic Challenge Listing more than 500 sky targets, both near and far, in 187 challenges, this observing guide will test novice astronomers and advanced veterans alike. Its unique mix of Solar System and deep-sky targets will have observers hunting for the Apollo lunar landing sites, searching for satellites orbiting the outermost planets, and exploring hundreds of star clusters, nebulae, distant galaxies, and quasars. Each target object is accompanied by a rating indicating how difficult the object is to find, an in-depth visual description, an illustration showing how the object realistically looks, and a detailed finder chart to help you find each challenge quickly and effectively. The guide introduces objects often overlooked in other observing guides and features targets visible in a variety of conditions, from the inner city to the dark countryside. Challenges are provided for viewing by the naked eye, through binoculars, to the largest backyard telescopes. Philip S. Harrington is the author of eight previous books for the amateur astronomer, including Touring the Universe through Binoculars, Star Ware, and Star Watch. He is also a contributing editor for Astronomy magazine, where he has authored the magazine’s monthly “Binocular Universe” column and “Phil Harrington’s Challenge Objects,” a quarterly online column on Astronomy.com. He is an Adjunct Professor at Dowling College and Suffolk County Community College, New York, where he teaches courses in stellar and planetary astronomy.

Two composite Hubble images of the Sting Ray Nebula taken in 1996 and 2016 in (R:G:B) = (F658N,F656N,F502N) = the emission lines of ([N ii], Hα, [O iii]). Both images are shown with the same absolute intensities in each filter. Nebular emission from Hen3-1357, the youngest planetary nebula (Bobrowsky, 1994, ApJ, 426, L47), unexpectedly appeared sometime during the 1980s (Parthasarathy et al. 1993, A&A, 267, 19). Since then the central star has rapidly faded (e.g., Schaefer & Edwards, 2015, ApJ, 812, 133). The integrated emission fluxes of these three lines in the images above decreased by factors of 0.20, 0.37, and 0.6, respectively, over 20 years. As expected, the rates of fading are much higher in regions of highest emission measure as N+, H+, and O++ recombine.
