NASA said a meteor travelling at 75,000 miles per hour exploded over Massachusetts and nearby New Hampshire shortly after 2pm on Saturday, sending loud booms across parts of the north-eastern United States with an energy release equivalent to about 300 tons of TNT.
The agency said the fireball broke apart over north-eastern Massachusetts and south-eastern New Hampshire at an altitude of 40 miles, with residents in the area reporting a sudden blast strong enough to rattle homes.
