Giant radiation bubbles created by monster black hole feeding frenzy, new study suggests

"Now, with new data from eROSITA, researchers suggest a possible single cause for all these bubbles: incredibly powerful jets from Sgr A*, the supermassive black hole at the center of the Milky Way, which blasted outward about 2.6 million years ago."

2.6 million years ago is a very young age here. I note too that more than 8,000 molecular clouds documented claiming star formation, these are all very young too, perhaps all < 30 Myr. Looks like plenty of intense activity in the MW in the geologic recent past. Catastrophism all over it seems :)
