Meteor explodes over U.S. with blast equivalent to 300 tonnes of TNT

A meteor exploding with the force of 300 tonnes of TNT lights up the sky over Massachusetts and New Hampshire, NASA confirms.

In breve

A meteor exploded over northeastern Massachusetts and southeastern New Hampshire on Sunday with a blast equivalent to 300 tonnes of TNT, as confirmed by NASA infrasound sensors. Witnesses reported a green and white fireball and a loud boom, with no injuries or damage. The object was likely a 1-2 meter asteroid that vaporized mostly, with no debris confirmed. This event is notable for occurring over a populated area, though similar-sized objects enter the atmosphere several times a year typically over oceans. The exact size and potential fragments remain uncertain.

Punti chiave

• Meteor exploded over northeastern US with blast equivalent to 300 tonnes of TNT — Confirmed by NASA infrasound sensors and witness reports.
• Event occurred over northeastern Massachusetts and southeastern New Hampshire — Exact location per NASA official.
• No injuries or property damage reported — Only rattled windows and car alarms.
• Meteor was likely a small asteroid 1-2 meters in diameter — Based on velocity and energy yield; no direct observation of object before entry.
• Blast energy measured by infrasound sensors — Infrasound data used to estimate 300 tonnes TNT equivalent.

Contesto

A meteor exploded over the northeastern United States on Sunday with a blast equivalent to 300 tonnes of TNT, according to NASA, lighting up the sky over parts of Massachusetts and New Hampshire. The fireball broke up over northeastern Massachusetts and southeastern New Hampshire, said Jennifer Dooren, the U.S. space agency’s deputy news chief. The event occurred in the late morning, startling residents who reported hearing a loud boom and seeing a bright flash. No injuries or property damage have been reported so far, authorities said. The meteor’s breakup generated a shockwave that rattled windows and set off car alarms in several communities, according to local police dispatches. The American Meteor Society said it received hundreds of reports from witnesses who described the fireball as appearing green and white before fragmenting. The blast energy, measured by infrasound sensors,…

The article reports on a real, verifiable news event: a meteor explosion over the northeastern U.S. with a blast equivalent to 300 tonnes of TNT. The structured data provides high-confidence claims supported by authoritative sources including NASA (via Deputy News Chief Jennifer Dooren and infrasound sensors) and the American Meteor Society (witness reports). The content is coherent, cites specific details (location, time, energy yield, no injuries), and acknowledges unresolved uncertainties (exact size, debris). No fabricated or dangerously misleading elements are present. The high confidence reflects clear sourcing and factual grounding, with minor deductions for unresolved size/debris details that do not undermine publishability.
