射电天文学英文

天文学家把天空的星星，按区域划分成88个星座。其中，北部天空（以天球赤道为界）有29个星座；南部天空有46个星座，跨天球赤道南北的有13个星座。只要我们有耐心，数完一个里面的星星，再数下一个星座，是能数清用肉眼能看得见的星星。据天文学家计算的结果：0等星6颗；1等星14颗；2等星46颗；3等星134颗；4等星458颗；5等星1476颗；6等星4840颗……总共不超过7000颗。如果我们借助望远镜，情况就不同了，哪怕用一台小型天文望远镜，也可以看到5万颗以上的星星。现代最大的天文望远镜能看到10亿颗以上的星星。其实，天上星星的数目还远不止这一些。宇宙是无穷无尽的，现代天文学家所看到的，只不过是宇宙的很小很小的一部分。

UFO现象是本世纪最激动人心，最富有深远意义的事件。UFO现象中一些似乎违反自然规律的事件，极可能是现代物理学革命的前奏，因为历史上物理学的重大发现往往是从观察天空开始，而且UFO现象还可能与外星智慧有关。 它所显示的种种超出现代科学技术水平的功能，无疑是对人类智慧和当今科学技术的极大挑战。假如UFO真是外星人的乘具，外星人真的同地球人接触，那将会对地球文明产生全面冲击；对宇宙图景、科学体系、思维方式、哲学思想以至伦理道德方面，产生巨大的推动作用。因此，对UFO的研究极有可能导致人类文明的新飞跃。 但是目前，UFO研究一直徘徊在较低水平上，这不仅因为有关UFO的资料和数据十分缺乏，更重要的是因为对UFO存在著一些误解。其中最为典型的观念是「UFO=飞碟=外星人」，它可能使UFO研究误入歧途，历史常有惊人的相似之处。 牛顿为了解释运动的原因，创立了「第一推动力」学说，而不惜将后半生的大部分精力耗费在深奥玄虚的神学上。而当今UFO研究面临同样的境地：把UFO的神奇现象，简单地推到外星人身上。那比上帝难以捉摸的外星人假设，必然使UFO研究流于神秘空洞甚至肤浅，使它不能成为真正的科学，不能作为一门严格的科学而登大雅之堂，这与UFO及其研究所具有的深远意义极不相称。因此，有必要从哲学高度对UFO及其研究进行深刻的探讨，以期对UFO及其研究建立正确的认识，进而寻出正确的研究方向。 UFO phenomenon is the most exciting in this century, the richest events of far-reaching significance. UFO phenomenon that seemed unnatural events, most likely a prelude to the revolution of modern physics, because the history of important discoveries in physics are often started from the observation of the sky, and the UFO phenomenon and extraterrestrial intelligence may also be relevant.It shows all kinds of modern science and technology beyond the level of functionality, is undoubtedly the human wisdom and the great challenge of today's science and technology. If the UFO is really a ride with aliens, aliens really come into contact with the Earth, it will be the full impact of civilization on Earth; picture of the universe, science systems, ways of thinking, as well as ethics and moral philosophy, creating a huge role in promoting the . Therefore, the study of UFO very likely lead to a new leap forward in human civilization.But at present, UFO research has been hovering at a low level, this not only because of UFO related information and data is scarce, more importantly, because of the existence of UFO a few misconceptions. One of the most typical concept is "UFO = UFO = alien," which may cause UFO research from going astray, history often striking similarities.Newton In order to explain the reasons for the movement, the creation of a "first drive" theory at the expense will be the second for most of the energy spent in the profound mystery of theology. The UFO research today face the same situation: the magic of the UFO phenomenon, simply pushed to aliens who. That elusive aliens than God's assumptions, this will bring the UFO research tend to be superficial and even a mysterious empty so that it can not be a true science, can not serve as a strictly scientific and posted something presentable and acceptable, which has a UFO and its research disproportionate to the far-reaching significance. Therefore, it is necessary from a philosophical heights on the UFO and its depth of research,UFO and its research with a view to establishing a correct understanding, and then find out the right research direction.

我们看到的有恒星、行星、卫星、彗星、流星。我们看到的大部分是太阳系以外的恒星。只有行星和卫星是太阳系内的。
