自本月17日以来,世界各国的天文台对苏梅克一列维9号彗星对木星的大碰撞进行了紧张的观测.所获得的信息对于深化人类的天文知识并为解开地球上的某些自然灾变之谜有着重要的意义.在地球几十亿年的历史中,曾多次受到天外物体的撞击.一些古生物学家认为,6500万年前恐龙的灭绝是一颗直径数公里的小行星或彗星碰撞地球的结果.撞击产生的大量尘埃和碎片遮蔽了太阳,使地球变冷,植物死亡,恐龙在饥寒交迫中大量死去.美国著名的亚利桑那州的巴林杰陨石坑直径达1200米、深180米,据认为是在2万多年前一直径25—80米的铁陨石以每秒20公里的速度撞击形成的.有科学家指出,外来物体“造访”地球还引起了“通古斯大爆炸”.
Since the 17th of this month, the observatories of various countries in the world have conducted an intense observation of the large collision of the Somak-Loyo Comet 9 with Jupiter. The information obtained is of great help in deepening human astronomical knowledge and in unlocking some of Earth’s The mystery of natural catastrophe is of great importance and has been repeatedly hit by extraterrestrial objects for billions of years in the history of the Earth.A number of paleontologists believe that the extinction of the dinosaurs 65 million years ago was an asteroid with a diameter of several kilometers Or comets collide with the earth as a result of the impact of the large number of dust and debris generated by the sun shrouded the earth cool, plant death, dinosaurs died in a large number of hungry and cold.American famous Balinje crater diameter of 1200 meters deep 180 meters, is believed to have been formed over an iron meteorite 25 to 80 meters in diameter at a speed of 20 kilometers per second 20,000 years ago.According to scientists, foreign objects “visited” the earth also caused the “Tunguska Big Bang” .
