NASA says a meteor about five feet wide and weighing roughly 5.6 metric tons exploded off the Massachusetts coast Saturday afternoon, producing a loud boom heard across the region. The object traveled about 26 miles from northwest to southeast and broke up at an altitude of roughly 31 miles, releasing energy estimated at about the equivalent of 230 tons of TNT; some fragments may have fallen into the ocean. Investigators are reviewing public observations and sensor data to confirm debris locations and assess any recovered meteorites.
