Scientists have detected two gigantic bubbles of high-energy radiation spilling out from the Milky Way's center that may have erupted from a supermassive black hole.
The mysterious structures each span 25,000 light-years across, meaning that together they cover more than half the area of the visible sky, and are emitting gamma rays, the highest-energy wavelength of light.
The bulbous features may be evidence of a burst of star formation a few million years ago, researchers said. Or they may have been produced when a supermassive black hole in the center of our galaxy gobbled up a bunch of gas and dust.
