BOSTON – A loud boom that rattled homes and startled residents across Massachusetts on Saturday afternoon was likely caused by a meteor streaking through the atmosphere above New England, according to preliminary reports from astronomers and public safety officials.
The event unfolded shortly after 2:30 p.m., when residents from Boston’s northern suburbs to communities along the South Shore reported hearing what many initially believed was an explosion. Others described feeling a brief vibration strong enough to shake windows, rattle dishes, and send people outdoors looking for an explanation.
Local police departments fielded calls from concerned residents. Social media quickly filled with speculation ranging from an industrial accident to military aircraft activity. Some observers reported seeing a bright object moving across the sky moments before the sound was heard.
By late afternoon, attention had shifted toward a more unusual explanation.
Meteor observers began collecting witness reports from across New England describing a bright daytime fireball moving rapidly overhead. The reports suggested that a meteor entered the atmosphere at high speed before producing a sonic boom that could be heard across a large area.
Unlike thunder, which is generated by lightning, a meteor-related sonic boom occurs when an object traveling faster than the speed of sound compresses air in front of it, creating a shock wave that can travel for miles before reaching the ground.
The delayed arrival of that shock wave often creates confusion among witnesses. People may see a bright flash in the sky and hear nothing initially, only to experience a loud boom several minutes later.
Saturday’s reports appeared to follow that pattern.
Residents across eastern Massachusetts described hearing one or more explosive sounds despite clear weather conditions in many areas. Others reported feeling vibrations through walls and floors. The widespread geographic area covered by the reports suggested that the source originated high in the atmosphere rather than at ground level.
Scientists say most meteors burn up harmlessly before reaching the Earth’s surface. Even relatively small objects can produce dramatic visual displays and powerful sonic booms when they enter the atmosphere at tens of thousands of miles per hour.
Meteor events capable of producing audible booms are uncommon in New England, though they occur periodically around the world. Because much of the Earth’s surface is covered by water or sparsely populated areas, many go unnoticed. When one occurs over a densely populated region, however, the combination of a bright fireball and a sudden unexplained boom often generates widespread public attention.
