一、黑客和病毒作怪网络安全受到关注2000年,计算机黑客和计算机病毒屡屡侵扰著名网站,造成严重经济损失,计算机网络安全问题引起各国的极大关注,10月,美、英、法、俄、德、意、日和加拿大八国的计算机安全专家在德国柏林举行“反黑”大会,为保护计算机网络安全献计献策。二、美国“近地小行星约会”探测器进入小行星轨道美国国家航空航天局的“近地小行星约会”探测器于2月14日成功进入“爱神”小行星的轨道。科学家希望通过对“爱神”的质量、形状、磁场、引力场及矿物成分的探测,揭开小行星起源之谜,并寻找防止地球遭受小行星撞击的办法。三、距地球260亿光年的超远天体被发现参加“斯隆数字天空探索”计划的日、美、欧科学家利用哈勃空间望远镜拍摄到一个距地球260亿光年的
In 2000, computer hackers and computer viruses frequently invaded well-known websites and caused serious economic losses. The issue of computer network security has drawn great attention from all countries. In October, the United States, Britain, France, Russia, the United States, Computer security experts from Germany, Italy, Japan and Canada attended the “Anti-Triad” conference in Berlin, Germany, in an effort to protect computer network security. Second, the United States “near-Earth asteroid dating ” detector into the orbit of the astronautics NASA “near-Earth asteroid dating ” detector on February 14 successfully entered “Eros ” asteroid trail of. Scientists hope that by exploring the quality, shape, magnetic field, gravitational field and mineral composition of “Eros ”, we can find out the mystery of the asteroid’s origin and find ways to prevent the Earth from being hit by asteroids. Third, 26 billion light-years away from the Earth’s super-distant objects were found participating in the “Sloan Digital Sky Exploration” program, Japan, the United States, Europe scientists use the Hubble Space Telescope to shoot a globe 26 billion light-years
