Be sure to look up at the sky Tuesday night because the Perseid meteor shower is expected to be the most popular one of the year. The meteor shower will be most visible starting Tuesday night, into the early morning Wednesday hours. However, the brightness from the quarter moon is going to bring visibility down just a tad. NASA predicts about 15 to 20 meteors raining down an hour. So if you see a shooting star this week, it could be from the Perseid meteor shower. The peak of the Perseid meteor shower occurs overnight from August 11 to 12. On August 12, the shower’s radiant — the point on the sky from which shower meteors appear to originate — will be high in the northeast around 2 A.M. local time.
