Astronomie Quel jour sommes-nous ? Les quatre jours particuliers de l'année : équinoxe de printemps, solstice d'été, équinoxe d'automne, solstice d'hiver. La durée des jours varie, la hauteur du soleil dans le ciel aussi, l'endroit où il se lève et il se couche aussi. Une activité intéressante au préalable, c'est de distribuer les éphémérides de l'année aux élèves (on les trouve sur le calendrier des postes) et de rechercher : * les jours où le soleil se lève le plus tard (7 h 46, du 27 décembre au 5 janvier) * les jours où le soleil se couche le plus tôt (15 h 52, du 6 décembre au 16 décembre) * les jours où le soleil se lève le plus tôt (3 h 49, du 11 juin au 21 juin) * les jours où le soleil se couche le plus tard (19 h 56, du 19 juin au 1er juillet) [ les heures sont données en temps universel, selon le méridien de Paris : il faut ajouter 1 heure en hiver, 2h en été ; ajouter encore quelques dizaines de minutes si l'on habite à l'Est du méridien de Paris, en enlever si l'on est à l'Ouest !

The Planets (plus the Dwarf Planet Pluto) Our solar system consists of the sun, eight planets, moons, many dwarf planets (or plutoids), an asteroid belt, comets, meteors, and others. The eight planets that orbit the sun are (in order from the sun): Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. Easy ways to remember the order of the planets (plus Pluto) are the mnemonics: "My Very Excellent Mother Just Sent Us Nine Pizzas" and "My Very Easy Method Just Simplifies Us Naming Planets" The first letter of each of these words represents a planet - in the correct order. The largest planet is Jupiter. The inner planets are: Mercury, Venus, Earth, and Mars. Generally, the farther from the Sun, the cooler the planet. Density of the Planets The Earth is the densest planet.

Games@NOAA Phases of the Moon and Percent of the Moon Illuminated Copyright Antonio Cidadao. Used by permission. Click on picture to see large version. From any location on the Earth, the Moon appears to be a circular disk which, at any specific time, is illuminated to some degree by direct sunlight. Like the Earth, the Moon is a sphere which is always half illuminated by the Sun, but as the Moon orbits the Earth we get to see more or less of the illuminated half. During each lunar orbit (a lunar month), we see the Moon's appearance change from not visibly illuminated through partially illuminated to fully illuminated, then back through partially illuminated to not illuminated again. New Moon - The Moon's unilluminated side is facing the Earth. Waxing Crescent - The Moon appears to be partly but less than one-half illuminated by direct sunlight. First Quarter - One-half of the Moon appears to be illuminated by direct sunlight. Waxing Gibbous - The Moon appears to be more than one-half but not fully illuminated by direct sunlight.

Beginning and End of the Universe July 26, 2010 § Universe History * The diagram below outlines the major Eras of the Universe according to the Big Bang Theory. Click the picture for many more details and a larger image. The one line in the article that caught my attention the most was at the end. “One important point is that since everything that we learn about the Universe comes from light (photons), if there are no photons there is no information. That is a point that has been bothering me. via Astronomy 309: COSMOLOGY. Like this: Like Loading...

Le Bouvier, La Couronne Boréale et Hercule Le Bouvier Cette constellation en forme de cerf- volant se repère à partir de la Grande Ourse. En effet, Arcturus, une étoile très brillante au centre de la constellation se trouve dans la continuité de l’arc de cercle formé par les étoiles de la queue de la Grande Ourse (l’arc est dessiné en bleu). Le Bouvier est particulièrement bien visible au printemps. Cette constellation porte différents noms selon les régions. En Grande-Bretagne, le Bouvier est appelé « laboureur » car il se trouve derrière la charrue (le nom donné à la Grande Ourse). La couronne boréale Cette constellation formée d’étoiles rapprochées en arc de cercle se repère très facilement à côté du Bouvier. Cette constellation est bien gentille, car elle se voit très bien l’été pendant nos camps. La couronne boréale a été offerte à Thétys par Aphrodite en cadeau de noces. Hercule Attention, cette constellation n’est pas facile à voir la première fois ! Tu remarqueras que la constellation a la forme d’un homme agenouillé.

Windows to the Universe Virtual Tour: Panoramic Images: Smithsonian National Museum of Natural History This comprehensive virtual tour allows visitors using a desktop computer (Windows, Mac, Linux) or a mobile device (iPhone, iPad, Android) to take a virtual, self-guided, room-by-room walking tour of the whole museum. You can even browse a list of past exhibits, which is included on the ground floor map (see upper right map buttons). The visitor can navigate from room to room by clicking map locations or by following blue arrow links on the floor that connect the rooms. Please note: This tour is provided in Flash and HTML5 / Javascript versions. Please note: The National Fossil Hall is currently closed for renovation.

I don’t know about you, but I will have fun thinking abut this one this weekend. My definition of fun is different than most. “Scientists trying to explain the universe’s accelerating expansion usually point to dark energy, which seems to be pushing everything apart.But an Indiana University professor has a new theory, reports New Scientist: We’re inside a black hole that exists in another universe. Specifically, a black hole that rebounded, somewhat like a spring.Some fairly mind-blowing physics is involved here, but the gist is that Nikodem Poplawski of IU-Bloomington used a modified version of Einstein’s general relativity equation set that takes particle spin into account.” via Are We Living Inside a Black Hole?

The Earth/Moon System .br 1) Use checkboxes (Seconds, Minutes, etc) to choose time interval. "Hours" and "Days" work best for animation. Use slidebar at right to control simulation speed. There are 7 speeds, 3 forward (right), 3 reverse (left) and one neutral (center). 2) In top panel, Moon (dark or light gray, depending on phase) and Sun (yellow) are shown 4x too large. 3) Eclipse times are estimates only (good to within a few minutes). 4) Distances and sizes are not to scale 5) There is still a problem with the local time - it does not take into account the shift to/from Daylight Savings Time, and so may be off by an hour. prs@geol.niu.edu
