Chandra Release - September 11, 2019

Visual Description: GSN 069

An image of galaxy GSN 069 is displayed, featuring a large red dot in the pullout at lower left, and many small white-blue dots scattered around the field of view. The overall color of the image is predominantly black. The main panel of this graphic is a visible light image taken by the Digitized Sky Survey (DSS) around GSN 069, which is located in the center of the image. The inset contains a time-lapse of Chandra X-ray Observatory data taken over a period of about 20 hours on February 14 and 15, 2019, centered on the X-ray source in the middle of GSN 069. The sequence runs in a loop to show that the X-ray brightness of the source changes regularly and dramatically over the Chandra observation. Three X-ray eruptions are observed. To clearly show the Chandra source is located in GSN 069, the size of the box in the center of the DSS image is about ten times larger than the Chandra field in the inset.
