The Meteor Event Over New EnglandA meteor over Massachusetts during the weekend ultimately prompted reports of booms and sightings across New England into Canada. The American Meteor Society reported that the meteor was about 3ft (1 meter) wide as it entered the atmosphere around the New Hampshire border with Massachusetts, north of Boston.Scientific Confirmation of Natural PhenomenonOfficials with the US space agency NASA confirmed that the meteor was natural material, not a satellite or space debris – and that it entered the atmosphere at 2.06pm on Saturday. Robert Lunsford, the American Meteor Society program monitor, said the group received dozens of reports from Delaware to Montreal with people either hearing a double boom, feeling the ground shake or seeing the fireball.Speed and Impact AnalysisA NASA spokesperson, Allard Beutel, said the meteor was travelling at about 75,000mph (120,700 km/h) and probably fragmented about 40 miles (60km) above the ground. The agency estimated that the energy released when the meteor broke up was equivalent to about 300 tons of TNT, accounting for the booms that shook buildings across Massachusetts into Rhode Island.Regional Impact and Eyewitness AccountsThe double boom reportedly shook buildings across Massachusetts into Rhode Island. A dashboard camera in New York captured the meteor streaking across the sky there. People in a handful of states posted on social media about feeling the buildings they were in shaking. Several videos on the X platform captured what sounded like two quick booms, with no fire, smoke or other visual causes.Distinguishing from EarthquakesSeveral people filed reports with the US Geological Survey, registering the shaking they felt with the National Earthquake Information Center. The agency opened an event page based on the number of "Did you feel it?" reports it received on its website. However, there was no event registered on the agency's seismographs – meaning the shaking was not due to an earthquake.Meteor Behavior and Scientific ExplanationMeteors travel faster than the speed of sound, creating pressure waves as they burn and break apart in the atmosphere. That can produce a loud sonic boom that those on the ground can hear. Lunsford said it was unlikely the meteor struck the ground, noting that most meteors burn up before they hit the ground, and if this one didn't, it would have landed in the ocean.

The Meteorite Impact: A Cataclysmic Event What would it have been like to have lived through the meteorite impact that wiped out the dinosaurs 66m years ago? Writing in the Conversation, Michael Benton, of the University of Bristol, and Monica Grady, of the Open University, describe in vivid detail how it might have felt. The Initial Blast and Its Immediate Effects The first sign that something was amiss would have been a new star visible for about a week before the event. Upon its arrival, all living creatures near the impact site would have seen the bright fireball, heard its crackling noise and experienced a sonic boom before being swiftly incinerated. The Global Devastation Five minutes later, 100-metre-high mega tsunamis rolled across the Gulf of Mexico and, combined with the overheating, earthquakes, hurricanes and fires, wiped out everything within a 1,200-mile (2,000km) radius. The Long-Term Consequences Dinosaurs roaming forests on the other side of the world were still oblivious, but not for long. Within an hour, dust had circled the planet and skies had darkened. Within a day, global temperatures were dropping, and by the end of the week the world was 5C cooler. A ferocious winter lasted for more than a decade, eliminating about 75% of all species. A Warning for the Future Our ancestors were some of the lucky survivors but, sadly, Benton and Grady suggest our penchant for burning carbon is setting the scene for a similar scale of planetary catastrophe.

A meteorite event occurred over Ohio on Tuesday morning, producing a significant sonic boom that was felt across a wide area, including parts of Pennsylvania. According to NASA, the meteorite entered Earth's atmosphere at approximately 9 am local time. The meteorite, described as a small asteroid about 2 meters in diameter and weighing around 6 tons, moved at a speed of 45,000 mph. This event caused widespread reports of a loud boom, with residents in Cleveland and as far east as Pittsburgh, Pennsylvania, and into New York state, describing the sound as similar to fireworks or thunder. NASA's meteoroid environment office confirmed that the asteroid was spotted near Medina, Ohio. Despite its relatively small size, the meteorite produced a considerable sonic boom, which was captured on video by a National Weather Service (NWS) employee in Pittsburgh. The NWS's Cleveland office confirmed that satellite data suggested the boom was caused by a meteorite. So far, there have been no reports of debris being found, although it's possible that small fragments may have fallen to Earth. NASA noted that about 17,000 meteorites fall to Earth annually, but most burn up in the atmosphere. The agency also stated that space rocks smaller than a football field typically break apart in Earth's atmosphere, although they can occasionally explode in mid-air.
