[酷图]前往银河系中心之旅。

Explanation: In Jules Verne's science fiction classic A Journey to the Center of the Earth, Professor Hardwigg and his fellow explorers encounter many strange and exciting wonders. What wonders lie at the center of our Galaxy? Astronomers know of some of the bizarre objects which exist there, like vast cosmic dust clouds, bright star clusters, swirling rings of gas, and even a supermassive black hole. Much of the Galactic Center is shielded from our view in visible light by the intervening dust and gas, but it can be explored using other forms of electromagnetic radiation. This haunting wide angle image of the Galactic Center region in infrared light was constructed using data from the Midcourse Space Experiment (MSX) satellite. The image maps three mid-infrared bands, otherwise invisible to human eyes, into visible blue, green, and red colors revealing the thermal emission from dust clouds near the galactic center that have been heated by starlight. The galactic plane runs along the middle of this image while the galactic center itself is the bright spot at picture center. The field of view of this cropped picture is about 1.5 by 2.5 degrees.

銀河核心之旅

說明: 在威恩 (Jules Verne)的科幻名著-地心之旅 (A Journey to the Center of the Earth)裡，哈威格教授和他一同探險的伙伴，看見了許多奇異且動人的奇景。 那麼，我們銀河的中心又藏著什麼奇景呢？ 天文學家已經知道部份藏在那兒的奇特天體，其中有巨大的塵埃雲、明亮的星團、環狀的雲氣、以及一顆超大質量的黑洞。 不過銀河中心受到塵埃和雲氣的阻隔，所以在可見光波段幾乎是看不到，只有借助其他的電磁波段去探測它。 上面這張銀河核心的奇異紅外線廣角影像，是從中途太空實驗衛星 (MSX satellite)的數據建構出來的。 它把在三個中紅外線波段拍攝的紅外光影像，用藍色、綠色和紅色來著色，使人類肉眼無法看見的景象得以呈現出來，也讓我們可以探索銀河核心附近塵埃雲受到星光照射，因而發出熱輻射的情景。 銀河盤面橫過這張影像的中央，而影像中心的亮點就是銀河的核心。 這張經過裁剪的影像涵蓋之天區約是1.5度乘2.5度。
