🪐 The quasar 3C 454.3 in the constellation Pegasus is a cosmic powerhouse, shining around a trillion times brighter than our Sun due to a supermassive black hole feasting on matter at its core. Meanwhile, the pulsar PSR B1937+21, located about 9,000 light-years away, spins nearly 642 times per second—so fast that it's called a "millisecond pulsar," acting like a fantastically precise cosmic clock as it beams radio waves across the galaxy. ✨ #quasars⚡#pulsars⚡#cosmiclighthouses⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
