Giant Bubbles Seen in Milky Way Galaxy

The scientists found two giant bubbles that contain powerful radiation of energy out of the Milky Way galaxy.
They estimate the bubble is an explosion of black hole.
Two mysterious bubbles, each of which is about 25 thousand years cayaha, emit gamma rays, high energy light waves.
Visibility of the bubble is, the scientists said, proves that true big explosion before the star clusters formed several million years ago.

Or, perhaps, they were formed when the supermassive black hole in our galaxy millions of gas and ash spewing into the sky.

"We still do not know persisis source of the bubble is," said Doug Finkbeiner of the Harvard-Smithsonian Center for Astrophysics.

Finkbeiner and his team conducted observations using NASA's Fermi Gamma-ray Space Telescope, which is capable of mapping the gamma rays in space.

Both the bubble is really dramatic, mysterious, and very large. They emit the amount of energy nearly equal to 100 thousand exploding stars or supernovae, Finkbeiner said.
Writing about this discovery immediately dala of The Astrophysical Journal published an upcoming issue.
