Scientists Recreated What a Blazar Looks Like From Nearly 30 Years of Evidence — Take a Look
The new visualization uses 27 years of telescope data and a neural-fields algorithm to show different parts of the jet moving at different speeds.
- Caltech researchers reconstructed a jet of plasma from a blazar located in the constellation of Hercules, about 5.5 billion light-years from Earth, using 27 years of telescope data.
- The team analyzed 116 epochs from the MOJAVE program at 15 GHz, using a video-reconstruction algorithm called "kine" to weave older telescope images into a cohesive visualization of the plasma flow.
- Instead of standard pixel technology, researchers used neural fields to document movement inside the jet. This revealed different parts of the blazar move at varying speeds, providing unprecedented resolution.
- Published in Nature, the video was described as "astronomy's summer blockbuster." Lead author Dr. Marianna Foschi noted the surprising lack of shock waves in the plasma flow.
- This breakthrough technology will likely create many more high-resolution images, with one team member describing it as "a new kind of canvas for building a picture of our universe.
