X-ray image of Sagittarius A* (IMAGE)
Caption
This X-ray image of the galactic centre merges all Swift observations from 2006 through 2013. Sagittarius A* is at the centre. Low-energy (300 to 1,500 electron volts) X-rays appear red. Green are medium-energy (1,500 to 3,000 eV). Blue are high-energy (3,000 to 10,000 eV).
