The article you cited offers two possible explanations, that the Milky Way recently had an active galactic nucleus or that the Milky Way recently underwent a burst of star formation.

Iv'e tried searching here for this: http://www.nasa.gov/home/hqnews/2010/nov/HQ_M10-157_Chandra_Update.html

Maybe these two have something in common?

If not; anyone else see or hear anything on the link I posted?

In the future, how about the intensity of the ray , increase or decrease?
And the size ll be bigger then now?
Our solar system is in the local-fluff.
When our solar system ll go out there, the ray intensity ll be intense.

The main proposed source of the newly discovered bubbles seems to be an explosion from the center of the galaxy.
However, could the bubbles have come before the galaxy?
I remember a Scientific American article years ago (can't locate it) that argued that galaxies were formed from the disks where bubbles touched each other.
It would explain why galaxies are disk shaped and randomly oriented.
Perhaps the newly discovered bubbles are remnants of these older formation bubbles.
