Astronomers are highlighting a firework-like supernova remnant produced by a stellar explosion that people on Earth witnessed 845 years ago, around the year 1181. The glowing structure, with wispy filaments radiating outward, is the leftover debris of that historic event. The striking images have drawn attention for connecting a modern astronomical object to an explosion recorded by observers centuries ago.
Why now: New imagery of the remnant visually resembles fireworks, drawing fresh interest to a supernova historically observed in 1181.
