Pinky bubble ..... finds NASA

Fermi gamma ray telescope finds out a huge pinkish feature in the center of our Milky way .
They announced that it has approximately 50,000 light years span length.
"What we see are two gamma-ray-emitting bubbles that extend 25,000 light-years north and south of the galactic center," said Doug Finkbeiner , Astronomer , who first observed this bubble.

The work of further research is taken up by  Simona Murgia, a Fermi research associate at the SLAC National Accelerator Laboratory in Menlo Park, CA.
Possibilities of the origin of the bubble include that it may be an out come of a huge star burst (star formation) or may be a a particle jet from the super massive black hole at the galactic center , as we have seen many such jets in the other near by galaxies.
And what I feel personally is this thing .....  If antimatter-dominated regions of space existed, the gamma rays produced in annihilation reactions along the boundary between matter and antimatter regions would be detectable. So according to this fact , the bubble may even consists of anti matter which led to the release of gamma rays .

Anyways this feature is even expected to carry with it , some mysteries of the Origin of the universe , which is the ultimate thought of every Astro lover :)
