Fireballs from Heaven: To be or not to be?

Assuming a thermal breakup for 73P, Wiegert and colleagues have calculated the most likely trajectory of its dust cloud. Their results: dust should reach Earth in 2022, “producing a minor meteor shower–nothing spectacular. However,” he adds, “the ongoing splitting of the comet means new meteoroids are being sent in new directions, so a future strong meteor shower from 73P…

Fireball spewing Comet Schwassman-Wachmann returning in 2011

The revelation that Schwassmann-Wachmann (hereafter SW3) left a cosmic calling card during it’s last pass is significant.  The comet returns every 5.4 years.  The next pass should be around November 2011.

Green fireballs that streaked across the sky and rolled down an Australian mountainside four years ago, spurring reports of UFOs in the area, might have been meteors and ball lightning, a researcher suggests. At least three traffic-light green fireballs brighter than the moon but not as bright as the sun blazed over northeast Australia on May 16, 2006. A farmer saw one with a blue tapering tail…
