Astronomers have scoured decades-old data from NASA's Chandra X-ray Observatory, finding bright, lumpy features dotting a jet of energy spit out by a nearby black hole. Puzzlingly, the "knots" clock a faster speed when seen in X-rays than they do in radio wavelengths. scientists said.
"The X-ray data traces a unique picture that you can't see in any other wavelength," study lead author David Bogensberger, an astrophysicist at the University of Michigan, who led the new study, said in a recent news release. "We've shown a new approach to studying jets and I think there's a lot of interesting work to be done."
