Executive Summary
- A pulsar, traveling between 1 and 2 million miles per hour, likely collided with a large galactic filament (G359.13 or 'The Snake') near the center of the Milky Way, causing a fracture.
- The collision distorted the filament's magnetic field and warped its radio signal, which was observed using NASA's Chandra X-ray Observatory, the MeerKAT radio array in South Africa, and the National Science Foundation's Very Large Array.
- The discovery highlights the dynamic interactions between celestial objects in our galaxy and provides insight into the structure and evolution of galactic center filaments.
Event Overview
Astronomers have identified a likely cause for a fracture observed in a large cosmic filament located near the center of the Milky Way galaxy. The filament, known as G359.13 (or 'The Snake'), is a 230-light-year-long structure visible in radio waves. Using data from NASA's Chandra X-ray Observatory, the MeerKAT radio array, and the Very Large Array, researchers determined that a fast-moving pulsar, a rapidly spinning neutron star, likely collided with the filament, causing a break or fracture. This collision distorted the filament's magnetic field and warped its radio signal, providing valuable insights into the dynamics of the galactic center.
