棒旋星系NGC 1365确实是一个雄伟的岛屿宇宙,直径约20万光年。NGC 1365距离微弱但炽热的天炉座仅6000万光年,是被充分研究的天炉座星系团的主要成员。这张令人印象深刻的彩色图像显示了靠近星系中央棒的末端和沿其旋臂的强烈的红色恒星形成区域。从细节上看,模糊的尘埃带穿过星系明亮的核心。其核心是一个超大质量黑洞。天文学家认为,NGC 1365突出的棒状结构在星系的演化中起着至关重要的作用,它将气体和尘埃吸引到恒星形成的漩涡中,并最终将物质输送到中心黑洞中。

Barred spiral galaxy NGC 1365 is truly a majestic island universe some 200,000 light-years across. Located a mere 60 million light-years away toward the faint but heated constellation Fornax, NGC 1365 is a dominant member of the well-studied Fornax Cluster of galaxies. This impressively sharp color image shows the intense, reddish star forming regions near the ends of the galaxy's central bar and along its spiral arms. Seen in fine detail, obscuring dust lanes cut across the galaxy's bright core. At the core lies a supermassive black hole. Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing gas and dust into a star-forming maelstrom and ultimately feeding material into the central black hole.
