The black hole studied in November was 300 million light years away, but the super-massive black hole observed by Schlegel and his colleagues is just 26 million light years away in the Messier 51 galaxy system.
The black hole sits in the centre of a small spiral galaxy that's working on merging with a second, larger spiral galaxy. It's likely that this cohabitation gave the black hole some gaseous material to chow down.
Using Nasa's Chandra X-ray Observatory, the researchers spotted twin arcs of X-ray emissions from the black hole in question, which they believe to be the after-effects of a big meal that happened millions of years ago.
They also noted a burst of colder hydrogen gas in the trajectory of the jets, suggesting that the hot burp had "snow ploughed" other gases into shape on its way out into the galaxy.
Meanwhile, researchers have found you can observe a nearby, active black hole with a 20cm telescope.
As material from surrounding space falls into them, violent bursts of light are released - which can be seen.
"We now know that we can make observations based on optical rays ... and that black holes can be observed without high-spec X-ray or gamma-ray telescopes," lead author Mariko Kimura, a master's student at Kyoto University, said.
