A mysterious boom that rattled homes and sparked confusion across Massachusetts and the wider Northeast on May 30 has now been traced to a fast-moving meteor, with NASA providing new details.
What Happened Over New England
Residents across eastern Massachusetts began reporting a loud, sudden explosion-like noise around 2:06 p.m. EDT on Saturday, with some describing a loud boom that shook buildings.
The disturbance was felt across a wide swathe of the region, prompting a surge of emergency calls as people questioned whether it was an earthquake, an industrial blast, or even a military event.
But tracking data quickly pointed to a far more unusual culprit: A meteor streaking through Earth’s atmosphere.
In a statement shared on X, NASA confirmed that both eyewitnesses and a satellite detected “a bright fireball” moving over New England at the time of the incident.
According to NASA: “The meteor appears to have fragmented at an altitude of 40 miles over northeast MA and southeast New Hampshire. The energy released at breakup is estimated to be equivalent to about 300 tons of TNT, which accounts for the loud noise.”
TNT is a chemical compound commonly used as an explosive, and an event releasing 300 tons of TNT produces a powerful shock wave (otherwise known as a sonic boom) that can shake buildings and rattle windows. It sounds like a large explosion, even though it happens high up in the sky.
Eyewitness Reports: ‘Felt the Shockwave’
Eyewitness accounts collected by the American Meteor Society and local media paint a vivid picture of the moment the meteor disintegrated.
One witness told local media: “I was outside in Framingham with my dog. Heard and felt two huge blasts. Felt the shock wave. Definitely not thunder.”
Another described the experience as similar to an explosion: “Thought it may have been an explosion from the power plant next door. It vibrated my apartment…Did not sound like thunder.”
Someone on X said, “I honestly thought a tree fell near my house. It shook the house when it happened.” Another agreed: “In East Watertown, we heard a very loud boom and the house shook. I thought a tree fell on the roof.”
Doorcam footage, posted by users on X, captured the loud boom:
In addition to the noise, dozens of people reported seeing a bright fireball streak across the daytime sky, an unusual sight given that most meteors are only visible at night.
According to The Associated Press (AP), Robert Lunsford of the American Meteor Society said the object was “definitely bigger than a normal fireball,” describing it as “about a yard wide.”
Why It Happened
According to the American Meteor Society, meteors are fragments of space debris that enter Earth’s atmosphere at extremely high speeds—often between 25,000 and 160,000 miles per hour.
Most are tiny and burn up harmlessly. However, larger fragments, like this one, can penetrate deeper into the atmosphere before disintegrating.
In this case, as the meteor encountered increasing resistance, it heated rapidly, broke apart, and released an intense burst of energy, producing the sonic boom heard across multiple states.
Was It Dangerous?
Despite the dramatic sound and widespread reports, officials confirmed there were no injuries or significant damage linked to the event.
The Executive Office of Public Safety and Security posted this statement on X, after the boom was heard, before NASA confirmed it was a meteor:
“This afternoon, Massachusetts Public Safety Officials received reports of an audible boom and ground tremors in Eastern Massachusetts. Although we do not yet know the cause, there are no known emergency police or fire requests connected to these reports, and we do not believe there is any public safety threat.”
The U.S. Geological Survey also ruled out an earthquake, noting that the event was a “widely felt sonic boom from a suspected bolide [large meteor]” and that the shaking people felt was consistent with a sonic boom traveling through the atmosphere, not ground movement. “While recorded on seismic sensors, traditional earthquake magnitudes are not appropriate for measuring atmospheric events. No magnitude is assigned.”
Could It Happen Again?
Events like this are rare but not unheard of. Thousands of meteors enter Earth’s atmosphere every day, but most are too small or occur over unpopulated areas to be noticed.
Larger fireballs capable of producing sonic booms occur only occasionally, and predicting exactly when and where one will appear remains nearly impossible.
