The Cosmic Lighthouse Has Switched ⚡ экспресс
Original: "NICER observations reveal doubled timescales in Ansky's quasi-periodic eruptions (QPEs)"
A supermassive black hole in a distant galaxy has started emitting X-ray flares half as often and four times more powerful than before.

The cosmic lighthouse switched: a black hole in a distant galaxy now blasts X-ray flares every 10 days, half as often but four times stronger. Perhaps this is how a star behaves on its final loop before being swallowed.
🎯 Although the flares repeat almost like clockwork, the interval between them can drift slightly, so they are called quasi-periodic (nearly periodic).
🎬 Stories about signals from extraterrestrial civilizations may come to mind, but here it's pure physics at work.
