X-Ray Factory Revealed in the Center of Our Galaxy
This X-ray image of the galactic center merges Swift XRT observations through 2013. Sgr A* is at center. Low-energy X-rays (300 to 1,500 electron volts) are shown in red, medium-energy (1,500 to 3,000 eV) in green, and high-energy (3,000 to 10,000 eV) in blue. The total exposure time is 12.6 days.Credit: NASA/Swift/N. Degenaar (Univ. of Michigan)
