James Webb telescope finds 'remarkable' evidence that a black hole plowed through a galaxy, leaving an enormous scar behind

Astronomers using the James Webb Space Telescope and ALMA have made a groundbreaking discovery of a superlong and narrow 'galactic contrail' that suggests a black hole has passed through a galaxy, leaving a massive scar. This tail of gas and dust stretches an astonishing 20,000 light-years long but is only 650 light-years wide. This finding is significant as it enhances our understanding of black holes and their impact on galaxy formation and evolution.
