1994年7月7日,一场千古罕见的天文奇观发生在茫茫宇宙中,苏梅克——利维9号彗星在飞经太阳系九大行星之一木星附近时,被体积是地球300倍的木星所吸引,巨大的引力使苏梅克——利维9号彗星碎裂成了21块碎片。在宇宙中排成了如项链般的一串光点,以时速21万公里猛向木星撞击。巨大的碎块直径达数公里。接连不断的撞击使木星上爆炸出了耀眼的亮光和巨大的云团,撞击时飞溅起来的物质冲到了木星上空1000公里的高空。据天文望远镜拍出的照片显示,每个撞击点形成的黑斑都有一个或数个地球大,爆炸产生的能量相当于几亿颗原子弹的威力。这一千载难逢的天文奇观使全世界的天文学家都兴奋不已,他们彻夜不眠地观测,收集到了无数宝贵的天文资料,对研究宇宙的演变以及地球和人类史都有巨大的作用。
On July 7, 1994, a rare wonders of astronomy wonders in the vast universe. When the Comet of the Sumeik-Levy 9 flew through Jupiter, one of the nine major planets of the solar system, by 300 times the volume of the Earth Attracted by Jupiter, huge gravitational force made the Comet of the Sumeik-Levy 9 fragment into 21 fragments. Lined in the universe, such as necklace like a string of light spots, the speed of 210,000 kilometers per hour fierce Jupiter hit. Huge fragments up to several kilometers in diameter. A series of bursts of light sparked Jupiter’s bright lights and huge clouds, spilling material that burst into space at a height of 1,000 kilometers over Jupiter. According to the pictures taken by the astronomical telescope, the dark spots formed by each impact point have one or more large earths, and the energy produced by the explosion is equal to the power of hundreds of millions of atomic bombs. This once-in-a-world astronomical spectacle has thrilled astronomers all over the world. They watch all night long and collect countless valuable astronomical data that have a huge impact on the evolution of the universe and on the earth and human history.
