Three New Pulsars Discovered in Ancient Galactic Dance🌌
In a celestial discovery that's music to astronomers' ears, China's Five-hundred-meter Aperture Spherical radio Telescope (FAST) has tuned into the rhythmic pulse of Messier 15, an old Galactic globular cluster residing 35,700 light years away. The cosmic symphony reveals three new pulsars, adding fascinating notes to the stellar composition. Pulsars, those highly magnetized, rotating neutron stars emitting electromagnetic radiation, are no strangers to Messier 15. Yet, FAST has uncovered a trio that steals the spotlight this time. Two boast leisurely spins, earning the title of long-period pulsars, while the third dazzles as a millisecond pulsar, whirling with rapid intensity. The standout, PSR J2129+1210J, commands attention as an isolated millisecond pulsar, showcasing a mesmerizing spin period of 11.84 milliseconds. Meanwhile, its companions, PSR J2129+1210K and PSR J2129+1210L reveal their distinctive long-period rhythms, marking an extraordinary celestial dance withi...
