COMET FIREBALL: Bright fireballs appear somewhere on Earth every day. Most are caused by rocky asteroids. On Friday, May 20th, however, a less common object struck. Sky watchers in the southeastern USA watched a big but fragile piece of comet break apart in Earth's atmosphere. The resulting fireball was the brightest meteor observed in nearly 3 years by NASA's all-sky network of meteor cameras.
