More than 100 filaments have been detected since Yusef-Zadeh’s first encounter in the early 1980s.

The menagerie of filaments is clustered around the supermassive black hole at the center of our galaxy. “They haven’t been found elsewhere,” says Yusef-Zadeh

New observations of the galactic center have revealed a pair of giant bubbles at the center of the Milky Way that give off radio emissions, according to recent research published in Nature. The bubbles stretch outward from the black hole and extend into space in opposite directions. The filaments that Yusef-Zadeh discovered all those years ago are encased within.

These bubbles are big. Top to bottom, the cosmic hourglass measures 1,400 light-years

The discovery suggests that the sinuous filaments arose as part of a larger structure. “We’ve long thought that this was the case, but we haven’t been able to image the proof,”

The bubbles look like a carefully spun, delicate work of interstellar art. But they are the aftermath of a violent, cosmic cataclysm that unfolded millions of years ago.

Well that's a fairly unscientific assumption... slightly disappointed in the close-mindedness, but whatever...

“Something happened, in a very short period of time, a few million years ago at the center of the galaxy,”

Mmhm and with the previous statement, it appeared you were claiming to know ALLLL about.

Camilo and other astronomers are considering a couple of explanations. A flurry of dying stars at the center of the galaxy might have infused the medium with enormous amounts of energy as they exploded. Or it could be that the black hole experienced a flare-up, as black holes around the universe have been known to do. Sometimes, black holes consume nearby stellar material so quickly that they end up regurgitating some of it. The result is two luminous jets of radiation that can outshine entire galaxies. Our supermassive black hole is in a quiet chapter of its life, but astronomers suspect that it has previously experienced this active phase.

Ah, here we go... their thoughts.

The ancient explosion inflated the bubbles and, as they expanded, excited the electrons that, together with nearby magnetic fields, produce radio emissions we can detect all the way from here.

Uh huh....

The heart of the galaxy is home to other bubbles, recorded in other wavelengths. The Fermi bubbles, named for the 20th-century scientist who studied high-energy physics, are even larger, stretching about 25,000 light-years above and below the galactic center. Astronomers discovered them nearly a decade ago with a space telescope designed to detect gamma rays. And they’re still trying to understand them. Camilo speculates that perhaps the Fermi bubbles might be the dumping grounds of eons of many cosmic explosions—a larger, older version of the radio-emitting bubbles his team found.

So all-in-all, they have no conclusive theory - let alone a solid grasp. Got it.

Neat discovery - I wonder what it really is. Article is kind of annoying how they forcibly inject their pseudo-religious presuppositions of sciencism/absolute-chaos into it though.
