銀河系的中心是什麼?在儒勒-凡爾納的經典科幻小說《地心遊記》中,裡登布洛克教授和他的探險同伴們遇到了許多奇特而令人興奮的奇蹟。天文學家已經知道銀河中心存在的一些奇異天體,包括巨大的宇宙塵埃雲、明亮的星團、漩渦狀的氣體環,甚至還有一個超大質量黑洞。由於塵埃和氣體的阻擋,我們無法用可見光觀察銀河中心的大部分割槽域,但我們可以用其他形式的電磁輻射來探索銀河中心。這段影片實際上是對銀河中心的數字縮放,首先利用的是數字化巡天拍攝的可見光影像。隨著影片的進行,顯示的光線轉為可穿透塵埃的紅外線,並突出顯示了最近於 2013 年發現的正在向中心黑洞墜落的氣體雲。
原文:What lies at the center of our galaxy? In Jules Verne's science fiction classic, A Journey to the Center of the Earth, Professor Liedenbrock and his fellow explorers encounter many strange and exciting wonders. Astronomers already know of some of the bizarre objects that exist at our Galactic Center, including 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. The featured video is actually a digital zoom into the Milky Way's center which starts by utilizing visible light images from the Digitized Sky Survey. As the movie proceeds, the light shown shifts to dust-penetrating infrared and highlights gas clouds that were recently discovered in 2013 to be falling toward the central black hole.
