木星 Jupiter

星,太陽系中的行星之王,直徑達地球的11倍,已知擁有63顆衛星,可說是一個小型的太陽系。長期的觀察可見木星上劇烈的大氣運動,大氣上著名的大紅斑便是一個存在超過100多年、有地球3倍大小的風暴,近月木星大氣出現了第二顆紅斑,天文學家稱之為小紅斑,是人類第一次看著紅斑的誕生。透過先鋒、航行者、伽利略、卡西尼太空探測船,科學家能夠近距離觀測木星系統,如捕捉木衛一艾奧的活火山爆發、探測木衛二歐羅巴的地底海洋、近距離觀察木衛三加美尼的地質活動、認知佈滿隕石坑死寂的木衛四卡尼斯托。此外,哈勃太空望遠鏡、地面的大型望遠鏡也對木星作長時間的觀測,在94年重要的天文現象休梅克利維9號彗星撞木星的時候更發揮重大的作用。

Jupiter, the King of planets, its diameter is 11 times of Earth, with its known 63 moons, it acts like a small solar system. From long term observations, we observe dynamic evolution of the jovian atmosphere, its famous Great Red Spot, is a gigantic storm on Jupiter for over 100 years, its size is 3 times our Earth. In recent months, Jupiter has a new red storm appeared, dubbed the Red Spot Jr., it is the 1st time ever human beings recorded the birth of a red spot on Jupiter. With the help of the spacecrafts Pioneer, Voyager, Galileo, Cassini, scientists are able to take a close-up look at the Jovian system such as volcanic eruptions on Io, hidden liquid ocean under Europa surface, geological activities on Ganymede, and the dead world Callisto filled with craters. More, ground based observatories and the Hubble Space Telescope also played an important role in observing Jupiter, especially in long term observations. In 1994, the Collision of Comet Shoemaker Levy 9 into Jupiter is a historical event that shocked the astronomical community.
