英仙座星系團中的NGC 1275
NGC 1275 in the Perseus Cluster

活動星系NGC 1275 是昴宿星系團中居核心地位的主導成員,該星系團規模龐大且相對鄰近。在可見光波段呈現狂野形態的它,同時也是強大的X 射線與射電輻射源。當整個星系墜入NGC 1275 時,其吞噬物質的過程最終將養育位於星系核心的超大質量黑洞。 這張清晰的望遠鏡影像採用窄帶成像資料,突顯了由此形成的星系碎片和發光氣體絲狀結構,部分絲狀體長達 2 萬光年。儘管星系碰撞的劇烈動盪本應摧毀這些絲狀結構,它們卻在NGC 1275 中持續存在。究竟是什麼力量維繫著這些絲狀結構? 觀測表明,這些被黑洞活動從星系中心推擠出的結構,正由磁場維繫著。這座被稱為英仙座A 的NGC 1275 星系本身跨度逾十萬光年,距離地球約 2 . 3 億光年。
原文:Active galaxy NGC 1275 is the central, dominant member of the large and relatively nearby Perseus Cluster of Galaxies. Wild-looking at visible wavelengths, the active galaxy is also a prodigious source of x-rays and radio emission. NGC 1275 accretes matter as entire galaxies fall into it, ultimately feeding a supermassive black hole at the galaxy's core. Narrowband image data used in this sharp telescopic image highlights the resulting galactic debris and filaments of glowing gas, some up to 20,000 light-years long. The filaments persist in NGC 1275, even though the turmoil of galactic collisions should destroy them. What keeps the filaments together? Observations indicate that the structures, pushed out from the galaxy's center by the black hole's activity, are held together by magnetic fields. Also known as Perseus A, NGC 1275 itself spans over 100,000 light years and lies about 230 million light years away.
