Something big is going on at the center of the galaxy, and astronomers are happy to say they don’t know what it is. A group of scientists working with data from NASA’s Fermi Gamma-Ray Space Telescope said Tuesday that they had discovered two bubbles of energy erupting from the center of the Milky Way galaxy. The bubbles, they said at a news conference and in a paper to be published Wednesday in The Astrophysical Journal, extend 25,000 light years up and down from each side of the galaxy and contain the energy equivalent to 100,000 supernova explosions.
Odd. I've never heard of anything like it. And I'm not sure what they mean by "energy." Normally, that term is not used to refer to a substance hanging around, but to refer to stored energy, so they must be referring to energized particles of some sort. They say it isn't dark matter, and isn't anything else they have seen before.The strange part is the sudden observation of these large pockets. the observers claim that they did not notice them, before, but is it possible that these pockets of energy simply weren't there until now? Perhaps something is causing this change in our galaxy.
