Time to stretch out the lawn chairs, lie back and enjoy the once-a-year celestial show known as the Perseid meteor shower.
The Perseids, the dusty debris of Comet Swift-Tuttle, whisk through our upper atmosphere every August. They aren't the only meteor shower on the calendar, but "the Perseids are the good ones," says meteorite expert Bill Cooke of NASA's Marshall Space Flight Center in Huntsville, Ala.
A U.S. radar system that tracks thousands of objects orbiting Earth — from satellites to harmful debris — has been slated for shutdown, according to the Space News site. The ground-based network known as the "Space Fence" may cease to operate in October.
Our nearest star is about to pull a once-in-11-years move by swapping its north and south magnetic poles.
The sun's polarity switch is a natural part of "solar max" — the period of peak activity during what averages out to be roughly an 11-year cycle. According to NASA, this year will mark the fourth time since 1976 that scientists have observed the 180-degree pole flip.
