(Portland, OR) -- Meteors hitting Earth are getting larger. In the last week, meteors caused sonic booms over Ohio and Texas. Part of the meteor in Texas damaged a house. A bright green fireball was spotted over the Northwest this week. Jim Todd, at the Oregon Museum of Science and Industry, says a review of global Fireball Logs shows there has not been an increase in the number of fireballs, but there has been an increase in their size, which means larger meteors are hitting Earth's atmosphere.
