If it turns out to be nothing more than a black hole's farts, it still looks awesome. I love being able to see all the invisible forces in the universe through picture filters and whatnot.

So what are these bubbles suspected to be made of? How much mass might they be adding to the gallaxy...?

'Supersonic' is not the word I would use for 1,000km/s.
It's more like 'kilosupersonic.'

Oh i know what the bubbles are, its all the orbiter vessels that have been flung into glitch trajectories over time. you know the ones, like when you accidentally time accelerate into the moon and suddenly appear 1.056e52AU from the sun traveling, you guessed it, 1000 km/sec

So is this still happening and it's still expanding? Surely that's a bad thing in some way, especially at that speed.

if it is bad, it's bad for someone else. We are off to the side of the fire hose, not in front of it.

Sagittarius A*, what have you been eating!?

Behold, the apotheosis of the Fart... Now Andromeda starts backing away...

Yeah, anybody who lives way outside the galactic plane would probably already be, like... some kind of interstellar Grizzly Adams. "Hmm...Builds character."

This thread always catches me by surprise, because whenever I read the title of "gigantic, mysterious structure in the Milky Way", I assume that someone's megaengineering project has been discovered.

Astronomy Now: Hubble dates black hole’s last big meal:
Quote:

This illustration shows the light of several distant quasars piercing the northern half of the Fermi Bubbles, an outflow of gas expelled by our Milky Way galaxy’s hefty black hole. The Hubble Space Telescope probed the quasars’ light for information on the speed of the gas and whether the gas is moving toward or away from Earth. Based on the material’s speed, the research team estimated that the bubbles formed from an energetic event between 6 million and 9 million years ago. The inset diagram at bottom left shows the measurement of gas moving toward and away from Earth, indicating the material is traveling at a high velocity. Hubble also observed light from quasars that passed outside the northern bubble. The box at upper right reveals that the gas in one such quasar’s light path is not moving toward or away from Earth. This gas is in the disk of the Milky Way and does not share the same characteristics as the material probed inside the bubble. Credit: NASA, ESA, and Z. Levy (STScI)
