NASA has confirmed that a 500-pound meteor about 2 feet in diameter entered the atmosphere over western Pennsylvania on early Tuesday morning, resulting in a massive fireball that lit up the pre-dawn sky.
The space rock was moving at a speed of 45,000 mph and was detected by three of the 15 black-and-white cameras NASA has installed around the country to capture such activity. NASA lost sight of the meteor at an altitude of about 13 miles, but based on calculations of its projected path, the agency speculated that fragments of the space rock could be found just east of Kittanning, Penn.
