网友：近来，关于黑洞、月壤、"星际访客"等天文学话题常常引发网上热烈讨论。我很好奇，目前天文 学的发展到了什么水平？将如何影响我们的生活？ 天文学是人类认识宇宙的科学。当人类文明尚处于萌芽之际，日月经天、斗转星移就成为人类认识自然 环境的朴素工具，由此去思考"昼夜更替""寒来暑往"。这种自发的探索宇宙活动，始于人类对神秘星空 的好奇心和求知欲。 探索宇宙，源自对未知世界的渴望 中国是世界上天文学起步最早、发展最快的国家之一，天文学也是我国古代最发达的自然科学之一。屡 有革新的优良历法、令人惊羡的发明创造、卓有见识的宇宙学说等，在世界天文学发展史上占据着重要 地位。世界上的四大文明古国在远古时期就开始了天文观测和研究。我国在公元前21世纪就建立了观象 台，部分古观象台、天文仪器等重要设施得以较好地保存。 随着综合国力的不断增强，我国天文研究和技术水平有了长足的进步和发展。我们拥有了具有世界一流 水平的研究团队，拥有占据世界领先水准的技术力量，成为国际天文学舞台上不可或缺的重要支柱。我 们凭借自己的智慧和力量建设了郭守敬望远镜、"中国天眼"、悟空号探测卫星等受到国际天文界关注的 大科学工程。我国在宇宙学、星系、黑 ...
