Possible Supernova Remnant Detected Near Milky Way’s Core
Astronomers using NASA’s Chandra and ESA’s XMM-Newton X-ray data, with radio and optical support from MeerKAT and Pan-STARRS, find a bright X-ray blob in the Sagittarius C region near the Galactic Center that could be a new supernova remnant. If confirmed, it would be one of the closest remnants to the Milky Way’s central black hole and is estimated to be about 1,700 years old, expanding at roughly two million miles per hour, though an alternative explanation involving a massive-star cluster remains possible and confirmation is pending.
