Stars are observed to orbit a very massive and compact object there known as Sgr A* (say “sadge-ay-star”...

首张黑洞事件视界尺度的影像

2022年5月1日 First Horizon-Scale Image of a Black Hole Image Credit: Event Horizon Telescope Collaboration Explanation: What does a black hole look like? To find out, radio telescopes from around the Earth coordinated observations of black holes with the largest known event horizons on the sky. Alone, black holes are just black, but these monster attractors are...

图示:宇宙早期的类星体

2022年2月22日 Illustration: An Early Quasar Illustration Credit & License: ESO, M. Kornmesser Explanation: What did the first quasars look like? The nearest quasars are now known to involve supermassive black holes in the centers of active galaxies. Gas and dust that falls toward a quasar glows brightly, sometimes outglowing the entire home galaxy. The qua...
