流星雨的出现，场面相当动人。我国古记录也很精彩。试举天琴座流星雨的一次记录作例：南北朝时期刘宋孝武帝“大明五年……三月，月掩轩辕。……有流星数千万，或长或短，或大或小，并西行，至晓而止。”(《宋书·天文志》)这是在公元461年。当然，这里的所谓“数千万”并非确数，而是“为数极多”的泛称。 而英仙座流星雨出现时的情景，从古记录上看来，也令人难以忘怀。请看：唐玄宗“开元二年五月乙卯晦，有星西北流，或如瓮，或如斗，贯北极，小者不可胜数，天星尽摇，至曙乃止。” (《新唐书·天文志》)开元二年是公元714年。
流星体坠落到地面便成为陨石或陨铁，这一事实，我国也有记载。《史记·天官书》中就有“星陨至地，则石也”的解释。到了北宋，沈括更发现陨石中有以铁为主要成分的。他在《梦溪笔谈》卷二十里就写着：“治平元年，常州日禺时，天有大声如雷，乃一大星，几如月，见于东南。少时而又震一声，移著西南。又一震而坠在宜兴县民许氏园中，远近皆见，火光赫然照天，……视地中只有一窍如杯大，极深。下视之，星在其中，荧荧然，良久渐暗，尚热不可近。又久之，发其窍，深三尺余，乃得一圆石，犹热，其大如拳，一头微锐，色如铁，重亦如之。”宋英宗治平元年是公元1064年。沈括已经注意到陨石的成分了。 在欧洲直到1803年以后，人们才认识到陨石是流星体坠落到地面的残留部分。 在我国现在保存的最古年代的陨铁是四川隆川陨铁，大约是在明代陨落的，清康熙五十五年(公元1716年)掘出，重58.5千克。现在保存在成都地质学院。 什么是流星 外空间的尘埃颗粒闯入地球大气，与大气摩擦，产生大量热，从而使尘埃颗粒气化。在该过程中发光形成流星。尘埃颗粒叫做流星体。 流星的速度 一个微小的流星体就足以产生在近百公里处就能看见的亮光，其原因就在于流星体的高速度。
流星的颜色 一个流星的颜色是流星体的化学成分及反应温度的体现：钠原子发出橘黄色的光、铁为黄色、镁是蓝绿色、钙为紫色、硅是红色。 流星的声音 流星通常不会发出可以听见的声音。如果你没有看到它的话，它就会悄无声息的一扫而过。对于非常亮的流星，有可能听到过声音。这些声响主要集中在低频波段。一个非常亮的流星，如火流星，可能会听到声音。 持久余迹 流星有时会在它通过的轨道上留下一条持久的余迹。余迹主体颜色多为绿色，是中性的氧原子。持续时间通常为1到10秒。可见余迹亮度迅速下降。这些亮光来自炽热空气和流星体中的金属原子。 流星雨 在某些时间，可以看到一定数量的流星的反向延长线都经过一个很小的天区。这些就是流星雨。 流星雨从何而 流星雨是由于彗星等天体破碎而形成的。彗星主要由冰和尘埃组成。当这些流星体的母体逐渐靠近太阳时，冰气化，使尘埃颗粒像喷泉之水一样，被喷出母体而进入彗星轨道。 流星体因何离开母彗星等天彗星周期。在地球穿过流星体群时，各种形式的流星。
Meteor shower is a very common phenomenon in astronomy, but you know the earliest meteor shower is recorded in the China? "Bamboo annals" in "the nightstars fell like rain" is the world's first meteor records, about 687 BC, is the earliestrecord of world Lyra meteor shower.
Findings and historical records of meteor shower
Meteor found and recorded, is China's earliest, "bamboo annals" in there "Diguififteen years summer night, stars fell like rain" records, the most detailed recordsin "Zuo Zhuan": "Lu Zhuang Gong seven years in April Xin Mao summer night, the stars were not seen, night stars fell like rain." Lu Zhuang Gong seven years BC687 years, this is the earliest record of world Lyra meteor shower. A meteorrecords of ancient China, there are about 180 times as much. The Lyridsrecorded about 9, about 12 times the Perseid meteor shower, Leonid meteor shower recorded 7 times. These records, study the evolution of meteor track,there will be important information.
The meteor shower appears, scene is beautiful. Ancient records of Chinese is excellent. A record attempt Lyrid meteor shower for example: Liu Songxiao Wu Di"Daming five years period of the northern and southern dynasties...... In March,lunar occultation of regulus....... A meteor tens of millions, or long or short, or big or small, and westbound to dawn, and check." ("song book, astronomical Chi")this is in the year 461. Of course, here the so-called "tens of millions" is notreally, but the general term "numerous". The Perseid meteor shower appearsscenarios, it seems from the ancient records, also unforgettable. Please see:Tang Xuanzong "Kaiyuan two years in May Yi Mao Hui, a star northwest flow, or if the urn, or as the Big Dipper, through the Arctic, the small countless, star doshake, to Shu Naizhi." ("new book of Tang, astronomical Chi") Kaiyuan two yearsA.D. 714.
Meteor crashed to the ground becomes a meteorite or aerosiderite, this fact, also recorded in china. "Records of the historian the day official book" in there "stars fell to the ground, then the stone" explanation. In the Northern Song Dynasty,Shen Kuo also found that meteorites have iron as main component. He in the"Meng Xi Bi Tan" volume twenty written in: "the first year of Changzhou YuZhiping, day, day to loud as thunder, is a big star, some say, in the southeast.Fewer and shock sound, moving along the southwest. Another shock and drop inYixing County in Hui Park, near and far for all to see, the firelight impressively asday,...... Regarded as only one orifice cup, deep. Recognizes, star in them,Yingying, however, for a long time fades and is heat can not be the last. And for a long time, the body, more than three feet deep, but a boulder, Judah and heat, itsas big as a fist, a micro sharp color such as iron, heavy as well as." The first year of song Yingzong Zhiping 1064 a.d.. Shen Kuo has taken note of the composition of the meteorite. In Europe until after 1803, people realized the meteoroid meteorite crashed to the ground part of the residue. In the ancient time of our country now save the siderite is Sichuan Long Chuan aerosiderite, is about in thefall of the Ming Dynasty, the Qing emperor Kangxi fifty-five years (AD 1716) toweight 58.5 kg. Now kept in the Chengdu College of geology. What is the dust particles into outer space meteor earth's atmosphere, and atmospheric friction,produce a lot of heat, so that the dust particle gasification. In the process of the formation of the meteor light. Dust particles called meteoroids. The meteor speeda tiny meteoroid is sufficient to produce in the 100 km can see light, its reason lies in the high velocity meteoroids.
Meteor colors a meteor colors is reflected in the chemical composition and the reaction temperature meteoroids: sodium atoms emit orange light, iron yellow,blue and green, calcium magnesium is purple, silicon is red. Meteor meteor do not usually issued voice can be heard the sound. If you don't see it, it will quietlysweep. For very bright meteor, have probably heard a voice. These sounds are mainly concentrated in the low frequency band. A very bright meteor, like a meteor, may hear the sound. Persistent meteor sometimes leave a lasting trails init through the track. Trails of subject color for the green, is the neutral oxygen atoms. Usually lasts for 1 to 10 seconds. Visible trails of brightness fell rapidly.The metal atoms that light from the hot air and meteoroids in. Meteor shower in the certain time, can see a certain amount of reverse the meteor to extend the line through a small area of the sky. These are the meteor shower. The meteor shower from where the meteor shower is broken due to comets and other celestial bodies formed. The comet is mainly composed of ice and dust. When the matrix of these meteoroids gradually close to the sun, ice gasification, makes dustparticles like the fountain of the water, was ejected into the orbit of comet parent.Why leave the parent comets meteoroids days comet cycle. In the earth through the meteoroid swarm, various forms of meteor.(责任编辑：最有料)
