Douglas Finkbeiner of the Harvard-Smithsonian Center for Astrophysics discussed the finding in a press conference Tuesday. Finkbeiner believes the "bubbles" may be "an outburst from the supermassive black hole lurking in the center of the galaxy,"
"This might be the first evidence for a major outburst of the black hole at the center of the galaxy. When it's going full-blast ... it would not actually take an enormous amount of time - maybe 10,000 or 100,000 years - for it to produce enough energy to create these structures," Finkbeiner said.Geekosystem presents another theory that scientists are also considering: "The bubbles also may have formed as a result of gas outflows from a burst of star formation, perhaps the one that produced many massive star clusters in the Milky Way's center several million years ago."
