A meteor that caused a loud boom heard in western Pennsylvania on New Year's Day exploded in the atmosphere with a blast equivalent to 30 tons of TNT, NASA said on Monday. The sounds were heard a few minutes before 11:30 a.m. ET on Saturday. Had it not been cloudy, the fireball would have been easily visible in the sky as it broke apart, according to a post on NASA's Meteor Watch Facebook page. NASA said a crude estimate indicated that the blast would have been about 100 times the brightness of the full moon.
