- 香港文化博物館 - Welcome To Chinese History. Planets in Orbit in 3D Animations with POV-Ray - Descriptions, tutorials and examples for the POV-Ray raytracing program. Look on My Works, Ye Mighty, and Despair! « Burrito Justice. Look on my works, ye Mighty, and despair! Shots from NASA’s Galileo space probe as it swung by the Earth and the Moon in 1992. (May take a minute to get going – click image for a larger version. Animation by Gordan Ugarkovic, via The Planetary Society.) Since the Mission is not actually visible in the above video, I will reuse this awesome shot of the earth rising over the horizon of the moon from Japan’s late Kaguya orbiter.
Hopefully this puts some things in perspective. That earth is beautiful, no? Next to the space program, infrastructure (specifically water and sewer systems) is likely our civilization’s crowning achievement. All of this is an excuse for me to publish this absolutely disgusting picture of what happens when you dump unnecessary crap down your drain, from our friends at the SF Sewers blog: You only appreciate this shit when it’s gone.
Oh, and Merry Christmas. Like this: Like Loading... Moon Phases Cycling GIF Information. Details This document describes the camera used to capture the lunar images. It goes on to discuss the visual size of the moon in each image, the process of aligning the images & the software used to create the final animation. The image you see above is ½ the 300x300 actual size, while the 'end of section' images are ¼ of the images natural size. To see the image unscaled, visit the Moon Phases Animation page. Image Capture The images seen in the above animation were captured on a Kodak DX6490 Zoom Digital Camera at full (10x) Zoom. Visual Size The size of the moon image in each crop was slightly different.
The moon is not in an entirely circular orbit around the Earth, it has an orbital eccentricity of 0.054. Aligning the Images The images were captured at slight different angles. Even when the images were aligned, rotated and resized to fit into the same visual space, there were differences introduced because of the north/south swing of the lunar orbit. Creating the Animation. New Page 1. If the sun were so much larger than the earth, Aristarchus argued that it was likely to lie at the center of the planetary system, with the earth orbiting it. He appreciated the issue of parallax in this system and correctly proposed that the stars are very far away compared with the size of the orbit of the earth: "that the sphere of fixed stars is of such a size that the circle, in which he supposes the earth to move, has the same ratio to the distance of the fixed stars as the center of a sphere has to the surface.
" Despite the supporting observations regarding the size of the sun, Aristarchus' concept was ultimately rejected in favor of keeping the earth at the center of the system. The reasons are not clear. It may have been that the conceptual difficulties with placing the stars so far away and the lack of any feeling of motion were too strong to overcome.
Earth And Moon. Earth & Moon Animation It takes the Moon 27.322 days to go around the Earth once. Because of this motion, the Moon appears to move about 13° against the stars each day, or about one-half degree per hour. If you watch the Moon over the course of several hours one night, you will notice that its position among the stars will change by a few degrees. The changing position of the Moon with respect to the Sun leads to lunar phases. Moon's Orbit and Rotation If you could fly to the Moon at a constant speed of 1000 kilometers per hour, which is the speed of a fast passenger jet, it would take sixteen days to get there. Apollo astronauts reached the Moon in less than four days even though they coasted "uphill" almost the entire distance. When the Moon is at apogee, it is 11% farther from Earth than it is at perigee.
Orbital characteristics - Moon. DSC04105.gif (306×311) Sketch. This page contains links to most of the astronomical sketches (along with a few CCD images and digital photos) on my web page, for quick access. Accompanying observing notes can often be found in my Online Observing Log or archives. Some of the sketches are pretty rough; others I'm pretty proud of. Many of the early ones were made with my 60mm refractor, the "Scope of Death". Since 2003, I've used a 10" Dob for most telescopic work. Deep-sky sketches may require adjustment of your monitor settings to gain the correct perspective of gray on black.

The December 2010 lunar eclipse occurred from 5:27 to 11:06 UTC on December 21, coinciding with the date of the December solstice. It was visible in its entirety as a total lunar eclipse in North and South America, Iceland, Ireland, Britain and northern Scandinavia. Occurrence[edit] The eclipse of December 2010 was the first total lunar eclipse in almost three years, since the February 2008 lunar eclipse.[2] It is the second of two lunar eclipses in 2010.
The eclipse was the first total lunar eclipse to occur on the day of the Northern Winter Solstice (Southern Summer Solstice) since 1638, and only the second in the Common Era.[4][5] Related eclipses[edit] This eclipse occurred at the descending node of the moon's orbit. The following two lunar eclipses will also be total, occurring on June 15, 2011, and December 10, 2011. See This lunar year cycle The next December solstice total lunar eclipse, as a Metonic twin eclipse, will be December 20, 2029 (19 years later), one day before solstice. 月球. 月球,俗稱月亮,古時又稱太陰、玄兔[5],是地球唯一的天然衛星[nb 4][6],並且是太陽系中第五大的衛星。 月球的直徑是地球的四分之一,質量是地球的1/81。 月球是太阳系内密度第二高的卫星,仅次于埃歐,它的自轉與公轉同步(潮汐鎖定),因此始終以同一面朝向著地球;正面標記著黑暗的火山熔岩海,中間夾雜著明亮和古老地殼的高地和突出的隕石坑。 雖然它的表面非常黑暗,反射能力與煤炭相似,但它仍是天空中除了太陽之外最亮的天體。 由于月球在天空中非常显眼,再加上規律性的月相變化,自古以來就对人类文化如語言、曆法、藝術和神話等产生重大影響。 月球的引力影響造成地球海洋的潮汐和每一天的時間延長。
月球現在與地球的的距離,大約是地球直徑的30倍。 月球是唯一一个人類曾經登陸過的地外星球。 名稱和語源[编辑] 中文的月是個象形文字,在甲骨文中的月像一彎眉月的樣子。 在英語中月的專有名稱是“the Moon”[7][8]。 形成[编辑] 大碰撞說的动画示意图,忒亚在地球的L5点形成,然后摇摆着进入碰撞轨道。 有数種機制都认为月球形成於45.27億± 0.10億年之前[nb 5],即大約是太陽系誕生之後的3,000萬至5,000萬年[11]。 當今主流的地月系統形成理論是大碰撞說:一顆火星大小的天體(被称为忒亚,神话故事中月球女神塞勒涅的母亲)與原生地球碰撞,爆裂出的物質進入環繞地球的軌道,經由吸積形成月球[16]。 大碰撞中所釋放的大量能量和之後在地球軌道上再作用的物質會熔化地球的外殼,形成岩漿海[20][21]。 另外一种假说则认为大碰撞产生了两颗在同一轨道上的卫星,一个就是月球,而另外一个较小,直径只有约1000公里。 物理特性[编辑] 內部構造[编辑] 月球內部的構造 月球是一个已經分異的天體,即它拥有地殼、地函、和核心。 月球是太陽系內密度第二高的衛星,仅次于埃歐[29]。 表面地質[编辑] 月球的地形。 月球是地球的同步自轉卫星,它繞軸自轉的週期與繞地球的公转周期是相同的,這使得它幾乎永遠以同一面朝向地球。
科学家曾經使用雷射測高儀和立體影像分析对月球表面的地形进行測量[34]。 表面地理[编辑] 月球是一个南北極稍扁、赤道稍許隆起的扁球。 火山地形[编辑] 在月球表面上用肉眼可以清楚看見有黑暗的,相對平坦的平原,我们称之为月海,這是因為古代的天文學家認為这些地方充滿了水[39]。 撞擊坑[编辑] Google 搜尋 圖片的結果. Moon Phases / Lunar Phases Explained. Have you ever wondered what causes the moon phases? We all know that its appearance changes over time. But why? The good way to understand the phases of the moon is to examine an earth-moon-sun diagram: ©MoonConnection.com All Rights Reserved.
This moon phases diagram is NOT public domain and may not be used on websites, copied, printed or republished except by permission. Diagram Explanation The illustration may look a little complex at first, but it's easy to explain. Sunlight is shown coming in from the right. One important thing to notice is that exactly one half of the moon is always illuminated by the sun. So the basic explanation is that the lunar phases are created by changing angles (relative positions) of the earth, the moon and the sun, as the moon orbits the earth. If you'd like to examine the phases of the moon more closely, via computer software, you may be interested in this moon phases calendar software.
