Massive Gamma Ray Bubbles Discovered In Milky Way

An anonymous reader writes "Two huge, mysterious gamma ray-emitting bubbles have been discovered at the center of the Milky Way galaxy, US astronomers said... The structure spans more than half of the visible sky, from the constellation Virgo to the constellation Grus, and it may be millions of years old."

    So far I am finding the original article an interesting read. (it's in the original article NYT article)
    It states that the bubble may be related to an ejection of the super massive black hole in the past 10 million years or so. You know those other galaxies that have giant lazer beams shooting out of them? Well, ours could have been like that at some point 10 million years ago. Kind makes sense that those SM black holes only occasionally and intermittently shoot stuff off, seems like just emissions like that would be hard to sustain for long periods of time. (and holy mother of Bohr, it was hard to not fall into sexual innuendo there)
    Also, as far as it being a data anomaly (which I thought first due to it's symmetry and the fact that we apparently never knew about it), it apparently correlates with "hard-spectrum excess known as the WMAP haze (and) the edges of bubble also line up with features in the ROSAT X-ray maps at 1.5 - 2 KeV."
