宇宙的形成1:卫星 Alien Moons

Posted by Editor on October 18, 2010 in 探索发现

本节目将带我们一起探寻宇宙是如何诞生的,又是如何从一个小点扩张到现在的浩瀚无际。首先我们认识卫星,卫星是指在围绕一颗行星轨道并按闭合轨道做周期性运行的天然天体或人造天体,月球就是最明显的天然卫星的例子。在太阳系里,除水星和金星外,其他行星都有天然卫星。太阳系已知的天然卫星总数(包括构成行星环的较大的碎块)至少有160颗。天然卫星是指环绕行星运转的星球,而行星又环绕着恒星运转。天然卫星的大小不一,彼此差别很大。其中一些直径只有几千米大,还有几个在太空运行的卫星却比水星还大。 This Is The Greatest Story Ever Told, The Creation Of Everything Us.

宇宙大爆炸是由宇宙中红移现象而推论得出的,宇宙在加速膨胀是有事实依据的,因此得出宇宙是由大爆炸中产生的结论,这些数据会激发人们无数的遐想,不可否认,人类已经开始了探索宇宙的新的旅程,这个过程肯定是刺激的。或许有一天人们发现红移现象是由另外原因产生的,那么大爆炸说就瞬间瓦解了。 Billions and billions of galaxies, the universe is so vast. We can’t even imagine what those numbers mean. But 14 billion years ago, none of these existed until the Big Bang. -The Big Bang is the origin of space and the origin of time itself. We take a journey through space and time, from [...]

黄石国家公园,(Yellowstone National Park)简称黄石公园,是世界第一座国家公园,成立于1872年。黄石公园位于美国中西部怀俄明州的西北角,并向西北方向延伸到爱达荷州和蒙大拿州,面积达7988平方公里。这片地区原本是印地安人的圣地,但因美国探险家路易斯与克拉克的发掘,而成为世界上最早的国家公园。园内设有历史古迹博物馆,它在1978年被列为世界自然遗产。黄石河、黄石湖纵贯其中,有峡谷、瀑布、温泉以及间歇喷泉等,景色秀丽,引人入胜。其中尤以每小时喷水一次的“老实泉”最著名。园内森林茂密,还牧养了一些残存的野生动物如美洲野牛等,供人观赏。(百度百科对黄石公园的详细介绍) As continents shift and clash,volcanos erupt,and glaciers grow and recede,the earth’s crust is carved in countless fasinating ways,leaving a trail of geological mysteries behind. One of the greatest is right here, in yellow stone national park in Wyoming. This is one of the world’s most geologically active places, shaken by up to [...]
