You can basically think of it as a hot plasma burp.
The researchers say this is the first time anyone has successfully picked up the radio signal produced by this jet of escaping matter. These black hole jets have been seen before, but they've never been directly linked to a star being torn apart -- and the phenomenon remains pretty mysterious.
"These events are extremely rare," study author Sjoert van Velzen, a Hubble fellow at Johns Hopkins University, said in a statement. "It's the first time we see everything from the stellar destruction followed by the launch of a conical outflow, also called a jet, and we watched it unfold over several months."
The deceased star was quite similar to our own, but sat a staggering 300 million light years away. It was done in by the type of supermassive black hole thought to sit in the center of most galaxies -- including our own.
Ohio State University scientists were the first to catch the murder in progress using an optical telescope, which they announced online in 2014. Along with researchers from the University of Oxford, van Velzen used different telescopes to gather optical, radio, and X-ray signals from the event as it unfolded. The researchers hope that they'll be able to catch more black hole burps in progress, so they can figure out the exact mechanism behind the purge.
