A three-light-year-long, cone-shaped cavity, expanding at 3.2 million km/h, has been observed near the Milky Way's supermassive black hole. This powerful, ancient explosion, detected using data from NASA's Chandra X-ray Observatory, suggests a supernova remnant at least 1,700 years old. Astronomers found this potential supernova remnant in the Sagittarius C (Sgr C) complex, just three light-years from Sagittarius A*, as reported by Universe Today.

While the region around Sagittarius A* is known for its extreme gravitational forces, the discovery of a relatively recent supernova remnant suggests a more dynamic and explosive history than previously assumed. This proximity challenges long-held assumptions about the galactic center's immediate environment.

Our understanding of the recent violent events shaping the galactic center is likely incomplete, requiring new models to account for such close-proximity supernova activity. This finding fundamentally rewrites the violent history of the galactic center, suggesting it's far more dynamically active than previously believed.

  • A potential supernova remnant was observed using data from NASA's Chandra X-ray Observatory, according to NASA (.gov).
  • This remnant is located within the Sagittarius C (Sgr C) complex near the Milky Way's supermassive black hole, as detected by astronomers, states Universe Today.
  • If confirmed, this object would be one of the closest supernova remnants ever discovered to our galaxy's central supermassive black hole, reports NASA (.gov).
  • The remnant, if confirmed, is expanding at approximately 3.2 million km/h, according to Universe Today.
  • The remnant is at least 1,700 years old, as also reported by Universe Today.
  • Powerful winds blow from Sagittarius A*, the supermassive black hole at the galactic center, according to Space.

A Violent Past Revealed Near Our Galaxy's Heart

A three-light-year-long, cone-shaped cavity was observed in a cloud of cold gas near Sagittarius A*, according to Space.com. This distinct physical evidence points to an ancient, powerful explosion in the galactic core. The X-ray emission from the suspected remnant is more than 10 times brighter than that of known stellar clusters with massive, young stars, as reported by Universe Today, indicating an exceptionally energetic event.
