Originally thought to originate from the disc in our galaxy. The data shows the bursts happening in all directions. This data is from 1991 to 2000.

Interactive graphic showing every known pulsar. Awesome!

This map shows the position of almost every known gamma-ray burst (often called GRBs), at least those for which astronomers have been able to measure a position (GRBs are often detected without any way of knowing where exactly they came from). The map is an equirectangular projection of the night sky in galactic coordinates, showing the entire sky as visible from Earth with our Milky Way galaxy running through the middle. The size of each circle illustrates the relative brightness (as seen from Earth) for each GRB, and the length of time each circle persists is scaled to 1/20th of the true length of the burst. Note that many of the earlier GRBs were detected by instruments that were not able to measure the true brightness or length of the burst - average values are used when showing these bursts on the map. The slider on top of the page lets you move through history, exploring when different GRBs were first discovered. Look to the counter in the top right to see what date range is currently shown, and click on any GRB to learn more about it. |
