Astronomers discover a gigantic, wobbling black hole jet that 'changes the way we think about the galaxy'

Astronomers using the Keck Observatory discovered the largest black hole jet ever observed in a nearby galaxy, extending 20,000 light-years and displaying a rare wobbling motion that strips star-forming gas at 20 solar masses per year. The discovery in galaxy VV340a challenges existing theories because such massive jets typically occur in older galaxies, not young merging systems like this one. This finding suggests supermassive black holes can dramatically reshape galaxies far beyond their cores and changes understanding of galactic evolution.
