AI stitches decades of observations into the sharpest view of a black hole jet yet

AI model Kine merged roughly 100 VLBA images of the blazar 3C 345 from 1995–2022 into a high‑resolution movie, four times sharper than any single frame. The video enables precise mapping of the jet’s motion, showing components racing at about 10–13 times the speed of light while surrounding gas moves at roughly 9–12c, offering fresh insights into jet dynamics across a 27‑year baseline.
