Where Milky Way galaxy
When Date Unknown
Photographer NASA/Daniel Wang, University of Massachusetts

"The center of the Milky Way galaxy blazes in this x-ray mosaic 900 light-years across. Our galactic center is a turbulent region, 25,000 light-years from Earth, packed with black holes, white dwarfs, neutron stars, and supernovae in a sea of multimillion-degree gas. Chandra's x-ray eyes show—for the first time with such clarity—the interplay between stars, gas, and dust. By detecting high-energy radiation, Chandra offers new perspectives on a clandestine universe."

—From "Super X-ray Vision," December 2002, National Geographic magazine
