The upper oval shows the entire sky, with the plane of our Galaxy running across the center. The lower portion is an expanded view of the crowded region of the sky near the center of our Galaxy. In this image, some notable X-ray Sources are located. Note that the Sun is depicted by an open circle. In the animations, the Sun moves as time goes on.
The X-ray objects are pinpoints, just like visible stars, but in the animation they are indicated with colored circles. The size of a circle represents the brightness. The color of the circle is the "X-ray color." Blue generally represents higher-temperature gases and red represents lower-temperature gases.
Here an outburst of 17095-266 is already in progress when the recurrent nova ql X-1 becomes bright. Aql X-1 became bright again in Aug 1997 and March 1998.
