What Giant Radio Pulses could teach us about radio signals from beyond the Milky Way

Pulsars are one of the more intriguing objects in the sky, radiating regular flashes of electromagnetic energy, which can (sometimes) be seen from Earth. Flashing with astonishing regularity, these objects are stellar corpses of massive stars that met their demise in supernovae. When beams of energy are aligned just right, they can be seen from Earth as regular pulses of light. Occasionally, pulsars produce unpredictable giant radio pulses (GRPs) — short-lived bursts of energy far more powerful than the flashes coming from the stellar corpse itself. New observations show X-ray emissions from the pulsar at the heart of the Crab…
