The radio galaxy Centaurus A, which is one of the brightest sources of radio waves in the sky, also radiates extremely high-energy gamma-rays, new observations from NASA's Fermi Gamma-Ray Telescope have found.

"This is something we've never seen before in gamma-rays," said Teddy Cheung, a Fermi team member at the Naval Research Laboratory in Washington, D.C.

Scientists think these gamma-rays, the highest-energy form of light in the universe, began as remnant radiation from the Big Bang thought to be the beginning of our universe about 14 billion years ago. But this radiation has been amped up to higher energy levels by the energetic particles zooming around magnetic fields in huge lobes that extend from either side of the galaxy, researchers said. This ramp-up in energy o
