The astronomers were mapping space's background glow of gamma rays, the brightest and most energetic type of light on the electromagnetic spectrum. They were surprised to find way more gamma rays coming from one part of the sky than anywhere else. AdvertisementAn artist's concept shows the entire sky in gamma rays, with the plane of our galaxy across the middle. Magenta circles indicate the area where astronomers found more high-energy gamma rays than average. Some unknown object or process out there in the universe may be producing both the gamma rays and the UHECRs.

NASA scientists have found a powerful new gamma-ray signal coming from outside our galaxy. AdvertisementNASA astronomers have discovered an unexpected "signal" coming from outside our galaxy, which they can't explain. The scientists were analyzing 13 years of data from the Fermi Gamma-ray Space Telescope when they noticed the mysterious signal. NASA's Fermi Gamma-ray Space Telescope, illustrated here, scans the entire sky every three hours as it orbits Earth. NASA's unexpected discovery could help astronomers confirm or challenge ideas about how the dipole structure is created.
