銀星砂 :: 天文講座 :: 望遠鏡探索宇宙四百年 [2008-01-17] 望遠鏡探索宇宙四百年 Cosmic Exploration with Telescope 400 Years
這是「宇宙探索新世代」講座系列的第一講,整個系列以人類探索宇宙為軸心,人類如何透過不斷的觀測去理解宇宙真締的故事,以下是第一講的簡介。 望遠鏡發明至今,快將四百年的時間,望遠鏡的出現打開了人類探索宇宙的窗口,並觸發了一場科學革命,締造了現代天文學的誕生。在這短短四百年時間,人類對宇宙的認知由遠古以來肉眼僅見的日月五星概念發展到今時今日的暗能量充斥、宇宙加速膨模型。四百年後的今天,探索宇宙的工具日新月異,十米級的地基光學望遠鏡相繼落成;不同波段的太空望遠鏡、天文衛星不斷揭開人類前所未見的宇宙探索新一頁。 This is the first lecture of the "New Era of Cosmic Exploration" lecture series, which would focus on how human beings explore the universe, and how do we understand the universe through observations and the stories behind. Below is the outline of the first lecture. It is almost 400 years since the invention of telescope, while the use of telescope marked the beginning of modern astronomy, which opened a window of universe for mankind to explore, and lead to a scientific revolution. In this short period of time, our understanding of the universe has been changed totally, from the vision of only 5 planets to a picture with dark energy dominated accelerating universe. After 400 years of telescope invention, the tools for cosmic exploration is everchanging, many giant telescopes with 10 meters aperture are constructed, satellites and multiwavelength observations are now opened new pages for our unseen universe.
