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. Lead author Dr. Marianna Foschi presented the high-resolution visualization.
- 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 plasma jet. This technique revealed different parts of the blazar move at varying speeds.
- Published in Nature, the video was described as "astronomy's summer blockbuster." Foschi noted the surprising lack of shock waves, stating, "In this case it was surprising to see that we don't have any shock waves at all."
- This breakthrough technology will likely create many more high-resolution images, prompting one team member to describe it as "a new kind of canvas for building a picture of our universe.
