"Wow."

That's how Princeton astrophysicist David Spergel summed up the news that will be published Wednesday in The Astrophysical Journal.

Scientists using NASA's Fermi Gamma-Ray Space Telescope said they discovered two bubbles of energy erupting from the center of the Milky Way Galaxy. The bubbles extend 25,000 light years up and down from each side of the galaxy and contain the energy equivalent of 100,000 supernova explosions.

One possible explanation is that the bubbles were fueled by a wave of star births and deaths at the center of the galaxy.

Wow.
