Although it's a well-known fact in astronomy, many people don't realize that when we see the Ring Nebula — the famed celestial oculi known as M57, whose hypnotic blue iris dazzles the northern constellation of Lyra — what we're actually seeing is the slow-motion death throes of a white dwarf star.
The catastrophic beauty of a dying star reaches its farewell crescendo when its crucible core surges with ionizing heat. The chemical light of its firework-spray nebula explodes in Technicolor spikes, wisps, rings — wild arcs that rip through the dark as the star thrashes off its atmosphere, shedding luminous clouds, as the Ring Nebula has, for thousands of years. Where once humans could only see the blurry glow of the Ring Nebula's distant fire, the latest images from NASA's James Webb Space Telescope have now given us a startlingly sharp map of its radiant halo and intricate inner-ring filaments, allowing us to discover for the first time what our own sun's final hours might look like.
