Milky Way’s Core May Hide an Ultra-Magnetized Pulsar

Scientists suspect a rapidly spinning, highly magnetic neutron star (a pulsar) sits near the Milky Way’s center. A Breakthrough Listen radio survey with the Green Bank Telescope (2021–2023) found a single pulsar candidate, BLPSR, around 122 rotations per second. If confirmed, such a pulsar orbiting Sagittarius A* could serve as a precise cosmic clock to test general relativity in the extreme gravity near the galaxy’s supermassive black hole, though the Galactic Center is notoriously hard to survey. Future facilities like ngVLA and SKA could help determine how many pulsars truly populate the core.
