NASA Backs up the folks at National weather Service Explanation of Loud Boom over the skies in Pittsburgh, Pa- NASA is weighing in on the very loud boom reported by many Pittsburgh, Pennsylvania residents on New Year's Day.
The space agency is backing up the report from the National Weather Service that the sound was that of an exploding meteor. NASA says the meteor was traveling at an estimated 45-thousand miles-per-hour (if you've ever ridden with Kristin Lessard , that'll be an all too familiar feeling) when it exploded with the force of 30 tons of TNT. (Can you even imagine what that would be like to see and hear ?!)
They add that, had it not been cloudy that day, the fireball would have been easily visible in the daylight sky with about 100 times the brightness of a full moon.
