What is this "gamma ray" glow from the center of our galaxy? As far as I understand these emissions usually come from super novae explosions, but there are not many supernovae in this part of the Milky Way.

I'm not sure *which* glow you're talking about. There is a 511KeV glow that is likely to be the result of Supernovae having given off many positrons which can fly through space for thousands of years before annihilating with some electron that crosses their path.

This is a guess but the gamma ray glow might be the combined output of numerous soft gamma repeaters (like Geminga and the Crab pulsar).

Would the item perhaps be a new noise detected by a NASA balloon (http://newswire.ascribe.org/cgi-bin/behold.pl?ascribeid=20090217.111132&time=11%2014%20PST&year=2009&public=0)?
