NASA has confirmed that a three-foot meteor exploded off the coast of Boston, creating a sonic boom heard across New England around
2 p.m. on Saturday. The meteor was traveling at
approximately 75,000 miles per hour when it fragmented at an altitude of
40 miles over northeastern Massachusetts and southeastern New Hampshire.
Residents reported hearing a double boom that rattled buildings and prompted police departments to investigate.
The explosion released energy equivalent to
300 tons of TNT.
Nobody saw smoke or fire, but many reported shaking sensations. This fireball was not associated with any known meteor showers and was a natural object flight, not space debris, according to
NASA's deputy news chief Jennifer Dooren.
Witnesses as far away as Delaware and Montreal reported hearing the booms and feeling the ground vibrate. Despite the perceived shaking,
there were no records of the event by the National Earthquake Information Center, ruling out an earthquake as the cause. Satellite imagery corroborates the meteor's trajectory.
The remnants of the meteor are believed to have landed in
Cape Cod Bay, where recovery teams may locate them due to their potential magnetic properties.
