    Scientists surveying the skies using NASA's Fermi Gamma-Ray Space Telescope have discovered two bubble-like structures apparently emanating from the center of the Milky Way.

    According to Discovery News, the gamma-ray bubbles span about half the length of the Milky Way (about 50,000 light-years) and contain the energy of 100,000 supernova.

    Astrophysicist 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," writes Discovery News.

    "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."

    Princeton astrophysicist David Spergel presented and discussed the Fermi bubbles alongside Finkbeiner. "This finding will be challenging astrophysicists for years," Spergel said, according to USA Today.

    Check out NASA's video (below), which explains how the Fermi bubbles may have formed; then scroll down for pictures. Official briefing materials on the discovery can be found at NASA.gov.

Since you're here... we have a small favor to ask...

More people are visiting & reading SPN than ever but far fewer are paying to sustain it. Advertising revenues across the online media have fallen fast. So you can see why we need to ask for your help. Donating to SPN's is vote for free speech, for diversity of opinions, for the right of the people to stand up to religious bigotry. Without any affiliation to any organization, this constant struggle takes a lot of hard work to sustain as we entirely depend on the contributions of our esteemed writers/readers. We do it because we believe our perspective matters – because it might well be your perspective, too... Fund our efforts and together we can keep the world informed about the real Sikh Sikhi Sikhism. If everyone who writes or reads our content, who likes it, helps us to pay for it, our future would be much more secure. Every Contribution Matters, Contribute Generously!
