太阳、地球与月球 The Sun , The Earth and The Moon

太阳

太阳是位于太阳系中心的恒星,它几乎是热等离子体磁场交织著的一个理想球体。其直径大约是1,392,000(1.392×106)公里,相当于地球直径的109倍。
The Sun is the star at the center of the Solar System. It is almost perfectly spherical and consists of hot plasma interwoven with magnetic fields. It has a diameter of about 1,392,684 km, about 109 times that of Earth.

地球


地球太阳系八大行星之一,按离太阳由近及远的次序排列为第颗。地球是太阳系的第三颗行星,也是太阳系中直径质量密度最大的类地行星。住在地球上的人类又常称呼地球为世界。地球是上百万种生物的家园,包括人类。地球是目前人类所知宇宙中唯一存在生命的天体。
Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar SystemThe planet is home to millions of species of life, including humans.Both the mineral resources of the planet and the products of the biosphere contribute resources that are used to support a global human population.

月球


月球,俗称月亮,古时又称太阴玄兔,是地球唯一的天然卫星,并且是太阳系第五大的卫星。月球的直径是地球的四分之一,质量是地球的1/81。
The Moon is the only natural satellite of the Earth, and the fifth largest satellite in the Solar System. It is the largest natural satellite of a planet in the Solar System relative to the size of its primary,having 27% the diameter and 60% the density of Earth, resulting in 181 its mass

Bersenam untuk sihat !(Let's do exercise 多多运动吧! )


Bersenam dan aktiviti fizikal juga memainkan peranan penting dalam memperbaiki status kesihatan, meningkatkan kecergasan serta membantu mengawal dan melawan penyakit.


Mechanism of The Seasons 四季的形成


season is a period of the year that is distinguished by special climate conditions. 
The four seasons—spring,summer, fall, and winter—follow one another regularly. 
Each has its own light, temperature, and weather patterns that repeat yearly.



Seasons occur because Earth is tilted on its axis relative to the orbital plane, the invisible, flat disc where most objects in the solar system orbit the sun. Earth’s axis is an invisible line that runs through its center, from pole to pole. Earth rotates around its axis.

Matahari - The Sun





The sun is a star, a hot ball of glowing gases at the heart of our solar system. Its influence extends far beyond the orbits of distant Neptune and Pluto. Without the sun's intense energy and heat, there would be no life on Earth. And though it is special to us, there are billions of stars like our sun scattered across the Milky Way galaxy.

Matahari adalah merupakan pusat bagi sistem suria (centre of the solar system).Matahari (Sun) adalah sejenis bintang (star), dan ia adalah satu-satunya objek dalam sistem suria/solar yang boleh memancarkan cahaya (radiate light) dan menjana tenaga sendiri. Matahari juga adalah bintang yang paling hampir dengan Bumi (Earth), iaitu kira-kira 150 juta km daripada Bumi.

月食 Lunar eclipse





月食月蚀,是一种当月球运行进入地球阴影本影部份)时,原本可被太阳照亮的部份,有部份或全部不能被直射阳光照亮,使得位于地球的观测者无法看到普通的月相天文现象。月发生时,太阳、地球、月球恰好或几乎在同一条直线上,因此月必定发生在满月的晚上(农历十五、十六、或十七),如《说文》所说“日蚀则朔,月蚀则望”。

lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the Sun, Earth, and Moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon. A lunar eclipse lasts for a few hours, whereas a total solar eclipse lasts for only a few minutes at any given place, due to the smaller size of the moon's shadow.

地球自转形成白天与黑夜 Day and Night


地球自转是地球的一种重要运动形式,地球绕自转轴自西向东的转动,从北极点上空看呈逆时针旋转,从南极点上空看呈顺时针旋转。地球自转一周的时间是1日。
白天和黑夜,亦可代指事物两个相反的方向。昼夜由自转产生,谓之“太阳日”,但昼夜的长度并非等于自转周期,因为当地球自转一周后,同时进行了公转,公转使地球对于太阳的相对角度发生变化,而昼夜是以太阳照在地球上的范围来看的,所以一昼夜比自转周期多3分56秒。当地球自转时,面向太阳之地面为“昼”,背向太阳之地面则为“夜”。


Earth's rotation is the rotation of the solid Earth around its own axis. The Earth rotates towards the east. As viewed from the North StarPolaris, the Earth turns counter-clockwise.
The Earth rotates around once in 24 hours - that's a rate of 1000 miles per hour!. The time it takes for the Earth to rotate completely around once is what we call a day. It's Earth's rotation that gives us night and day.

月相(Phase of the Moon )

 月相,天文学术语。(phase of the moon )是天文学中对于地球上看到的月球被太阳照明部分的称呼。随着月亮每天在星空中自西向东移动一大段距离,它的形状也在不断地变化着,这就是月亮位相变化,叫做月相。

Solar eclipse 日环食


Solar eclipse which occurred in China Year 2012   
5月21日凌晨5點多,中國境內多地出現日食景觀,部分地區出現日環食,環食時間最長達4分33秒。這次的日環食,是繼2010年1月15日後在國境內又一次可見的日環食,而下一次日環食將要等到2020年6月21日。圖為日環食拼接圖。
