Tonight the Earth passes through a trail of debris that a comet named 209P/LINEAR left behind. The comet, which is essentially a dirty snowball, leaves a debris trail when it approaches the perigee of its orbit around Sun. The Sun heats the comet which dislodges pebbles and rocks. When these little rocks strike the Earth's atmosphere: that's our meteor shower.
Experts are predicting 100 to 400 meteors per hour, which will peak sometime between late tonight Friday, May 23, 2014 and very early in the morning on May 24, 2014. If you live in the United States and Canada you'll have the best view. Go outside, find the north star, and enjoy the show. This is nature's fireworks display.
But if you're not able to watch it live outdoors, watch it live right here on TA and discuss it in the main chatroom.
