黑洞喷流能延伸多远？最近发现了一项新的记录，即从数十亿年前活跃的黑洞中发现了2300万光年长的射流对。这种令人印象深刻的喷流被称为卟啉翁（Porphyrion），是由一种通常不会产生长喷流的黑洞产生的，这种黑洞忙于从落入的气体中产生辐射。这段特色动画视频描绘了围绕这个强大的黑洞系统旋转的样子。卟啉体被显示为一种快速的高能粒子流，明亮的区域是这些粒子撞击周围气体的地方。这一发现是利用凯克和马约尔（DESI）光学天文台以及LOFAR和巨型米波射电望远镜的数据得出的。这些喷流的存在表明，黑洞不仅可以影响它们的母星系，还可以影响周围的宇宙。你的天空惊喜：APOD在你的生日上展示了什么照片？(1995后)

How far can black hole jets extend? A new record was found just recently with the discovery of a 23-million light-year long jet pair from a black hole active billions of years ago. Dubbed Porphyrion for a mythological Greek giant, the impressive jets were created by a type of black hole that does not usually create long jets -- one that is busy creating radiation from infalling gas. The featured animated video depicts what it might look like to circle around this powerful black hole system. Porphyrion is shown as a fast stream of energetic particles, and the bright areas are where these particles are impacting surrounding gas. The discovery was made using data from the Keck and Mayall (DESI) optical observatories as well as LOFAR and the Giant Metrewave Radio Telescope. The existence of these jets demonstrates that black holes can affect not only their home galaxies but far out into the surrounding universe.
