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.

NASA's Webb Unveils Bizarre Lemon-Shaped Exoplanet with Unique Atmosphere

Astronomers using the James Webb Space Telescope have discovered a unique, lemon-shaped exoplanet called PSR J2322-2650b, orbiting a pulsar at a very close distance. The planet has an unusual composition dominated by helium and carbon, with surface temperatures up to 3,700°F, and may represent a new class of cosmic object due to its peculiar shape and atmosphere. Its origins are uncertain, raising the possibility of a new type of celestial body.

Astronomers Find 'Forbidden' Pulsar Escaping Supernova in Milky Way

Astronomers discovered Calvera, a 'forbidden' runaway pulsar and supernova remnant located in a sparse region of the Milky Way, challenging previous notions about star formation in such areas. The system, about 13,000 to 16,500 light-years away and 10,000 to 20,000 years old, was detected by radio and X-ray telescopes, revealing that massive star remnants can exist far from the galactic plane, providing new insights into stellar evolution and supernova mechanisms.
