🪐 In 1967, astronomers discovered the first pulsar, now known as PSR B1919+21, a rapidly spinning neutron star that sends out regular radio pulses like a cosmic lighthouse. Unlike pulsars, quasars such as 3C 273 are the blazing hearts of distant galaxies, powered by supermassive black holes devouring matter and shining brighter than whole galaxies—making both objects among the most extreme and mysterious beacons in the universe. ✨ #pulsars⚡#quasars⚡#neutronstars⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries
