NASA Detects Nearby Mystery Explosion

starexplorer2001 writes "Space.com is reporting that NASA has detected a 'totally new' mystery explosion near our galaxy." From the article: "The event, detected Feb. 18, looks something like a gamma-ray burst (GRB), scientists said. But it is much closer--about 440 million light-years away--than others. And it lasted about 33 minutes. Most GRBs are billions of light-years away and last less than a second or just a few seconds."
