NASA | Radio Telescopes Capture Best-Ever Snapshot of a Black Hole's Jet

The video discusses how X-ray images reveal features of jets driven by galaxies, focusing on supermassive black holes. The Tanami project provides the best view of these jets. In radio images, the black hole is invisible, but the jets are visible in detail, resolving features as small as 15 light days. These powerful jets feed vast lobes of radio-emitting gas that extend far beyond the visible galaxy.

How small can the features of the jets be resolved according to the text?

What do the powerful jets feed into, and how far do they reach?
