Summary
116 VLBA images taken from 1995 to 2022 were turned into the highest-definition video yet of blazar 3C 345’s jet, tracing plasma motion with unprecedented precision.
A neural network called Kine reconstructed the animation at four times the resolution of any single image by learning changes across 27 years of observations from the 10-telescope U.S. array.
10-to-13-times-light-speed bright jet components emerged as a surprise because surrounding gas moved at about 9 to 12 times light speed, challenging expectations that shock features should outrun the flow.
The Nature study suggests AI-based video reconstruction could reshape how astronomers study variable black hole jets and measure velocity across their structure.
