在遙遠的星際空間中,有一個名叫NGC 1300的美麗螺旋星系。這個星系擁有一個明亮的中央條,沿著條的中心,有一個更小的螺旋星系。而在那個螺旋的中心,藏著一個超大質量的黑洞。NGC 1300距離我們約有7000萬光年,它位於天蝎座的河流埃里達努斯(Eridanus)星座中。哈勃太空望遠鏡拍攝下的這幅圖像,是對這個美麗星系最清晰的觀察之一。NGC 1300的直徑超過10萬光年,哈勃的照片顯示了星系中壯麗的中央條和壯觀的螺旋臂。科學家們仍在研究這個巨大的條是如何形成的,它是如何保持的,以及它對星星的形成有什麼影響。
原文:
Across the center of this spiral galaxy is a bar. And at the center of this bar is smaller spiral. And at the center of that spiral is a supermassive black hole. This all happens in the big, beautiful, barred spiral galaxy cataloged as NGC 1300, a galaxy that lies some 70 million light-years away toward the constellation of the river Eridanus. This Hubble Space Telescope composite view of the gorgeous island universe is one of the most detailed Hubble images ever made of a complete galaxy. NGC 1300 spans over 100,000 light-years and the Hubble image reveals striking details of the galaxy’s dominant central bar and majestic spiral arms. How the giant bar formed, how it remains, and how it affects star formation remains an active topic of research. Jigsaw Universe: Astronomy Puzzle of the Day
