When a double boom rang out in New England over the weekend, shaking homes and sending pets fleeing, questions started flooding social media.“Did anyone else hear that boom?”“Anyone feel that?”

An image taken from a video shows a view from a car dashcam when a meteor produced two loud booms over Cambridge, Massachusetts, on Saturday.

NASA let people know over the weekend that the cause of the commotion was a meteor, but on Monday they revealed even more stunning details.The fireball was as heavy as an elephant and 1.52m wide, and was going 67,592.5kph when it entered Earth’s atmosphere.

It broke up miles above New England on Saturday and the energy released was equivalent to about 230 tonnes of TNT, the agency estimated, accounting for the booms.
