This three-dimensional projection of the Milky Way onto a transparent globe shows the probable locations of all three LIGO events detected during the first observing run. Two are confirmed detections: GW150914 (green), and GW151226 (blue), while the third is a possible detection at lower significance (LVT151012, in red). The outer contour for each represents the 90 percent confidence region; the innermost contour signifies the 10 percent confidence region.
