Your Sky

by John Walker Welcome to Your Sky, the interactive planetarium of the Web. You can produce maps in the forms described below for any time and date, viewpoint, and observing location. If you enter the orbital elements of an asteroid or comet, Your Sky will compute its current position and plot it on the map. Each map is accompanied by an ephemeris for the Sun, Moon, planets, and any tracked asteroid or comet. Your Sky provides three ways to view the sky with links, where appropriate, among the various presentations. Sky Map The sky map shows the entire sky as viewed from a given location at a specified time and date. To make a sky map, enter the latitude and longitude of your observing site in the boxes below (be sure to check the correct “North/South” and “East/West” settings) and press the “Make Sky Map” button below the form. Horizon Views Horizon Views, showing the stars above the horizon as seen from a specified observing site at a given date and time.

Your Weight on Other Worlds Ever wonder what you might weigh on Mars or The Moon? Here's your chance to find out. <div class="js-required"><hr> This Page requires a Javascript capable browser <hr></div> Fill in your weight below in the space indicated. You can enter your weight in any unit you wish. Click on the "Calculate" button. Mass and Weight Before we get into the subject of gravity and how it acts, it's important to understand the difference between weight and mass. We often use the terms "mass" and "weight" interchangeably in our daily speech, but to an astronomer or a physicist they are completely different things. Weight is an entirely different thing. If you are in a spaceship far between the stars and you put a scale underneath you, the scale would read zero. The Relationship Between Gravity and Mass and Distance As stated above, your weight is a measure of the pull of gravity between you and the body you are standing on. The two "M's" on top are your mass and the planet's mass. Isaac Newton

Solar System Scope Peach Mountain Observatory Revised: June, 2004 Peach Mountain Peach Mountain is the home of the 24” McMath Telescope and is part of Stinchfield Woods. The circular structure on the left is the University of Michigan Radio Telescope. The oval structure on the right is a radio telescope which was put into operation in 1955, but has not been used for many years. A path is visible that leads from the small radio telescope to a rectangular building near the bottom of the photograph. The Observatory Building The McMath Telescope is located 700 feet from the 26 meter radio telescope on Peach Mountain. This is the telescope now used by the University Lowbrow Astronomers. The photo above shows the building housing the 24 inch McMath Telescope. The Comet Hale-Bopp is visible between the trees. This shows the north side of the observatory building.

Jeu de cartes MEMOSKY MEMOSKY a été créé en 2009 par Hervé DERYCKER, astronome, fondateur et directeur du Planétarium Observatoire de Briançon les Écrins de 1997 à 2015 (Hautes Alpes, France). L’auteur précise qu’il lui a fallu plus de 2500 heures d’expérimentations et de développement auprès de plus de 1200 personnes adultes, enfants et personnes ayant des difficultés de mémorisation pour mettre au point ce jeu de cartes qui ravira les adeptes de ciel étoilé et d’astronomie. Le jeu permet de mémoriser les étoiles, les constellations, les objets Messier (amas d’étoiles, nébuleuses, galaxies), mais aussi de localiser l’écliptique (zodiaque) pour l’observation des planètes. La codification des couleurs permet de repérer les étoiles et les constellations en fonction des saisons. Chaque carte est une vraie petite carte du ciel centrée sur une constellation, avec en plus le repérage de certains objets du ciel profond (amas d’étoiles, nébuleuses, galaxies).

Eppur si muove! Un modello del Sistema Solare con Scratch | omStaD Classe: dalla quinta primaria alla seconda della secondaria di primo grado, ma proponibile anche in altre classi modificando obiettivi e approfondimentiObiettivi: come si può realizzare un modello di un fenomeno? Se si utilizza un particolare strumento di modellazione ci saranno limitazioni al modello? Bisognerà sacrificare qualcosa? Descrizione Una simulazione con alcuni limiti dovuti allo strumento e alle dimensioni del fenomeno da analizzare. Inizio presentando il titolo “Eppur si muove!” Dopo il titolo apro Scratch per far intuire le forze in gioco nel moto dei pianeti, semplifico in base alla classe e, in ogni caso, anche perchè il moto circolare è abbastanza complesso di suo. Parlo di attrazione verso il Sole, fuga verso l’esterno per effetto della forza centripeta e conseguente forza centrifuga (il cestello della lava insalata o della lavatrice) e la rotazione che ne consegue, e, quindi, il moto di rivoluzione intorno al Sole. La Luna? Et voilà! E poi…

Solar System, Solar System Information Our Cosmic Neighborhood From our small world we have gazed upon the cosmic ocean for thousands of years. Ancient astronomers observed points of light that appeared to move among the stars. Since the invention of the telescope, three more planets have been discovered in our solar system: Uranus (1781), Neptune (1846), and, now downgraded to a dwarf planet, Pluto (1930). The four planets closest to the sun—Mercury, Venus, Earth, and Mars—are called the terrestrial planets because they have solid rocky surfaces. Nearly every planet—and some of the moons—has an atmosphere. Moons, Rings, and Magnetospheres There are 140 known natural satellites, also called moons, in orbit around the various planets in our solar system, ranging from bodies larger than our own moon to small pieces of debris. From 1610 to 1977, Saturn was thought to be the only planet with rings. Most of the planets also have magnetic fields, which extend into space and form a magnetosphere around each planet.

The Kepler Mission Education team has produced table top models demonstrating the principle of how Kepler will find extrasolar planets by the transit method. Components include: Orrery† (model planet system), Light (model star), Light sensor†† (model Kepler photometer), Computer interface (model Deep Space Network), and Computer graphic software (model Kepler Science Office) † The 1st orrery we created was one made of LEGO parts, described on this page.
