"Thanks to advances in computer power, since the 1990's we have been able to predict these upswings in activity," said William Cooke, head of NASA's Meteoroid Environment Office."This year there is going to be a Leonid strong outburst , where the rates may race up to 300 per hour," Cooke said.

&感谢计算的发展，从1990年开始我们就能预测到这些天文现象，&NASA流星体研究办公室负责人William Cooke这样说，今年将是狮子座流星群的一次大爆发，其数量可达到一小时300颗左右。

These streamings are then available to the individual who, like the planet, is a web of electromagnetic energy fields with points or nexi of entrance.
