[知識分享站] 用SRC琢磨瞬間出現的空中鑽石—日全食

本世紀最壯觀的日食現象在2009年7月22日發生，台灣則因地處稍偏，無緣見到「鑽石環」景象，但只要抬頭望便可看到日偏食呢！這次的日食現象引起全民對天文的關注，除了感官上奇妙的感受外，更能從中挖掘獲得天文科學知識，讓我們從SRC-Science Resource Center裡找到相關天文學資源，瞭解宇宙內幕吧！



Eclipse 日食/月食：

一個天上發光的物體被另外一個物體遮蔽住產生的現象，當太陽、月球、地球連成一直線時，就會產生日食或月食現象。An eclipse refers to the complete or partial blocking of the light of a celestial body by another body and can be used to describe a wide range of phenomena. Solar and lunar eclipses occur any time the Sun, the Moon, and Earth are all positioned in a straight line. This occurrence occurs uncommonly because the plane of Earth's orbit around the Sun is different than that of the plane of the Moon's orbit around Earth. Thus, the Moon is usually located just above or below the imaginary plane of Earth's orbit…..

Solar Atmosphere：太陽大氣

太陽直徑約140萬公里左右，是地球的109倍，只有大氣部份是可直接在地球上看得到的，太陽大氣層分為三層－分別是光球、色球和日冕，The Sun is about 865,000 miles (1,391,785 kilometers) in diameter or about 109 times the diameter of Earth. The only part of this giant, gaseous body that earthlings can view directly, however, is its atmosphere. The atmosphere consists of three general layers, the photosphere, the chromosphere, and the corona. No sharp boundaries mark the beginning of one layer and the end of another. Rather, transition regions exist in one layer, which gradually fades into the next….

Solar wind：太陽風

太陽風是從日冕傳出的帶電粒子流。The solar wind is an ongoing outward flow of electrically charged particles of ionized gas from the Sun' corona. The Sun's corona, an atmosphere of gases, extends millions of kilometers around the Sun. The particles of gas that make up the wind are not contained by the Sun's gravity and travel outwards billions of miles through the solar system and into interstellar space.
