At the center of this graphic of a short gamma-ray burst is a black dot representing a black hole. A cloud of debris, represented as a yellow-ish filled-in figure eight is centered on the black hole and tilted 45 degrees to the right. A pair of white-ish, cone-shaped jets are aligned with the figure eight and extend above and below the black holes. Additional debris is represented as a blue oval and a filled-in eternity symbol, both centered on the black hole and tilted 45 degrees to the left.

A large circular shape with rounded waves around the edge, this graphic gives the appearance of a flower. Smaller transparent circles with the same wavy edge are layered inward to create an inner starburst shape. While the outer rings are a muddy, light red color, the inner starburst shape is a darker color with green around its edge and dark blue in the center. White dots representing stars speckle the image.
