The Quiet Death of a Star ⚡ экспресс
Imagine a star simply switched off, like a light bulb. That's what happened in Andromeda: star M31-2014-DS1 went dark, and in its place now sits a black hole. Observations show the stellar remains slowly fading, like embers of a campfire. What exactly is making it dim so much?
In 2014, astronomers spotted a massive yellow star in the Andromeda galaxy. By 2022, it had vanished without a trace — without the usual blinding explosion of a supernova. It was as if someone simply switched off the light. Scientists suspected that the star's core quietly collapsed into a black hole, but the mystery was only solved with the latest instruments.
Thermal images from James Webb and the Chandra X-ray telescope revealed a ghostly scene. In place of the star, a dim reddish object is shrouded in a shell of carbon monoxide, carbon dioxide, and water vapor. This gas, expanding at 100 km/s, hides the central source, and the dust cloud stretches across 40–200 Earth-Sun distances — far beyond the orbit of Pluto.
The whole picture points to an incredibly weak explosion: the star didn't boom, it exhaled its outer layers before the core collapsed inward. The energy of this outburst was hundreds of times less than a typical supernova — true cosmic silence. Now the black hole barely glows (its brightness dropped to 7% of the original, and there's almost no X-ray emission) and only lazily pulls in the remaining matter. That's how some massive stars disappear without fireworks — turning into a cosmic shadow.
🎯 The cloud of this stellar 'soot' would swallow the entire Solar System with room to spare: its size is hundreds of times larger than Pluto's orbit — a true invisible smog around the newborn [tag:black_hole]black hole[/tag].
