AI Helps Astronomers Create Video of Black Hole Jet
Astronomers studied a distant object called a blazar.
A blazar is a supermassive black hole shooting a powerful stream of hot material into space.
The stream from 3C 345 points roughly toward Earth.
The object is about 5.5 billion light-years away.
Scientists collected 116 radio images over 27 years.
They used an AI program called Kine to connect the images and fill in missing parts.
This made the changing jet look more like a continuous video.
The clearer video may help scientists study how the plasma moves.
Caltech astronomers created a video of the blazar 3C 345, located about 5.5 billion light-years away.
The blazar’s supermassive black hole sends a high-energy plasma jet toward Earth.
Researchers analyzed 116 radio-telescope images collected between 1995 and 2022.
Lead researcher Marianna Foschi’s team used a neural-network algorithm called Kine to fill visual gaps.
The algorithm improved image clarity by about four times, allowing continuous tracking of the plasma’s movement.
