NASA confirms fireball over Massachusetts triggered loud boom, shaking

A fast-moving fireball turned a Saturday afternoon across Massachusetts into a public-safety mystery, with residents reporting a loud boom and shaking before scientists identified the culprit as a meteor, not an explosion or earthquake.

NASA said the object crossed over Massachusetts at 2:06 p.m. Eastern Time, traveling at an estimated 75,000 mph. When it broke apart, it released energy equal to about 300 tons of TNT, fragmenting about 40 miles above extreme northeast Massachusetts and southeast New Hampshire. NASA said the fireball was a natural object, not space debris or a satellite, and that it was not linked to an active meteor shower.

The Massachusetts Emergency Management Agency said public safety officials received reports of an audible boom and tremors in eastern Massachusetts, but there were no known emergency police or fire requests tied to those calls. The U.S. Geological Survey said there was no earthquake and described the event as a widely felt sonic boom from a suspected bolide, underscoring how easily a bright meteor can be mistaken for a blast or ground movement.

The first reports reached newsrooms at about 2:11 p.m., and people from Greater Boston and beyond quickly filled social media with descriptions of a bang that rattled windows, startled pets and shook some homes. Meteorologists said weather radar showed a flash in a place where there was no thunder activity, a detail that fit a bolide. Officials and forecasters also said confirmation could require finding debris on the ground.

The boom was heard across a wide swath of the region, stretching from northern New England to southern Rhode Island. CBS Boston said it drew dozens of calls and that the sound was heard as far away as Ipswich, Massachusetts, and Johnston, Rhode Island. The station also reported that the meteor likely entered the atmosphere over the South Shore near Boston, though no landing site had been identified.

The episode added to a series of high-profile fireballs seen across North America in 2026, including earlier meteor events over Ohio and Texas. NASA’s fireball database also lists an earlier Eastern Massachusetts fireball dated June 3, 2025, a reminder that rare sky events can still jolt crowded communities and trigger a rapid response from emergency officials, meteorologists and residents alike.
