"We cruised for them in our tight slacks which give us great bulges!"

The Milky Way appears as a relatively flat structure when viewed along its plane in visible light. Gamma-ray emission, however, paints a different picture: two huge structures billowing outward from the galaxy’s bulge like an enormous hourglass. Named the Fermi Bubbles, these structures are the result of the Milky Way’s supermassive black hole gorging itself on interstellar gas in the past. Using the Hubble Space Telescope (HST), astronomers have now determined just when these structured formed.
A team of astronomers led by Rongmon Bordoloi of the Massachusetts Institute of Technology has used distant quasars to trace the structure and motion of the northern Fermi Bubble, which rises 23,000 light-years above the plane of the Milky Way and contains enough cool gas to create 2 million Sun-size stars. By observing the ultraviolet light from 46 quasars with the Cosmic Origins Spectrograph (COS) on HST (and adding one quasar observation with HST’s Space Telescope Imaging Spectrograph), the team mapped out the motions of cool gas within the bubble to pin down its age: 6 to 9 million years.

A giant galactic belch.
I thought the bulge at my center, was from Milky Ways.
MILKY WAY: “Pull my finger...”
Until some one else claims something else
Well that sounds awkward...
Milky Way? Michael Moore’s on it like white on rice. What mystery?
Winner!
lol
Well that’s rather...suggestive.

I don’t know why they refer to this as a ‘mystery’, since the phenomena has been seen in other galaxies before. See next pic...............
The lead astronomer is... Rongmon.
