在遙遠的宇宙中,有一個叫做NGC 1365的巨大漩渦星系,它距離地球約56百萬光年,位於南方的星座Fornax。這個星系就像一個巨大而閃亮的旋轉陀螺,直徑達到200,000光年,這是我們自己的螺旋星系-銀河系的兩倍大!這張由詹姆斯·韋伯太空望遠鏡的中紅外儀器(MIRI)拍攝的清晰圖片展現了這個壯觀星系的美麗細節,用紅外光來探尋。在圖片中,我們可以看到大約60,000光年的範圍,觀察到星系的核心和明亮的新生星團。星系中的年輕恆星創造出精緻的塵埃絲網和氣泡,在旋轉的臂膀上,這些恆星就像小小的閃亮燈泡!天文學家認為,這個星系的中心部位的引力像是一個強大的吸塵器,將氣體和塵埃吸入,形成一個繁忙的新星誕生工廠,最終這些物質會進入這個活躍星系的中心,並餵養著超大質量黑洞。
原文:
A mere 56 million light-years distant toward the southern constellation Fornax, NGC 1365 is an enormous barred spiral galaxy about 200,000 light-years in diameter. That’s twice the size of our own barred spiral Milky Way. This sharp image from the James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) reveals stunning details of this magnificent spiral in infrared light. Webb’s field of view stretches about 60,000 light-years across NGC 1365, exploring the galaxy’s core and bright newborn star clusters. The intricate network of dusty filaments and bubbles is created by young stars along spiral arms winding from the galaxy’s central bar. Astronomers suspect the gravitational field of NGC 1365’s bar plays a crucial role in the galaxy’s evolution, funneling gas and dust into a star-forming maelstrom and ultimately feeding material into the active galaxy’s central, supermassive black hole.
