Meteor Fireball Over US Packs 300-Ton TNT Blast

On 2026-05-31, a meteor exploded over the northeastern United States with an energy release NASA estimated at about 300 tons of TNT. The blast produced a loud double boom and bright fireball but caused no reported damage or injuries, highlighting how often small space rocks enter Earth's atmosphere. Scientists are using sensor and radar data from the event to refine models of near-Earth objects and atmospheric entry.

Reported Facts

Observable data points shared across all narratives

•NASA estimated the energy of the meteor explosion over the United States at roughly 300 tons of TNT.
•Residents in parts of Massachusetts reported hearing a double boom when the meteor exploded.
•The meteor produced a bright fireball that was visible over sections of the northeastern US.
•Initial reports from local authorities in Massachusetts indicated no injuries or structural damage from the blast.
•US government and scientific sensors detected the fireball event and recorded its energy output.
•The explosion occurred high in the atmosphere, where the meteor broke apart due to pressure and heat.
•NASA classified the object as a small near-Earth asteroid or meteoroid that burned up before reaching the ground.
•Data from the fireball event will be added to NASA’s global fireball database used to study impact risks.

What Could Happen If...

▸If NASA’s analysis shows the meteor was larger than first estimated US and international space agencies may update public guidance on how often similar-sized objects hit the atmosphere.
