Perseid Meteor Shower Peaks Tonight

oxide7 writes "August's Perseid meteor shower has historically been providing the best opportunity for enthusiasts to catch meteor shows, but this year the Internet will let casual observers enjoy the show live online. The Perseids have been observed for at least 2,000 years and are associated with the comet Swift-Tuttle, which orbits the sun once every 133 years. Each year in August, the Earth passes through a cloud of the comet's debris. These bits of ice and dust — most more than 1,000 years old — burn up in the Earth's atmosphere."
