NASA Update On The 'BOOM' Heard In Pittsburgh On New Year's Day

NASA has issued their final update on the New Year's Day meteor that likely caused the "boom" heard in Pittsburgh on New Year's Day.

A post on the NASA Meteor Watch Facebook page said, "A nearby infrasound station registered the blast wave from the meteor as it broke apart; the data enabled an estimate of the energy at 30 tons of TNT. If we make a reasonable assumption as to the meteor’s speed (45,000 miles per hour), we can ballpark the object’s size at about a yard in diameter, with a mass close to half a ton."

NASA also added, "Had it not been cloudy, the fireball would have been easily visible in the daylight sky - crude estimate indicates about 100 times the brightness of the Full Moon."
