Unexplained Blinking Object in Space Mystifies Scientists for Over Three Decades

Astronomers have discovered a strange radio signal, named GPM J1839-10, that has been observed from Earth for at least 35 years. The signal resembles a pulsar but differs in key ways, suggesting it could be an extremely rare kind of magnetar with an ultra-long pulse period. The object's rhythm is far slower than normal pulsars, repeating roughly every 22 minutes. Its properties have eluded analysis since 1988 and could significantly impact our understanding of stellar life cycles.
