This weekend, over 100 meteors per hour will descend on Earth in the annual Perseid Shower, otherwise known as the "fireball champion." This shower contains the highest concentration of bright meteors, called fireballs, which are known for leaving bright, visible streaks in the sky as they fall, more so than any other recurring meteor shower. San Francisco's "Urban Astronomer" Paul Salazar explained what you can see in the night sky over the weekend.
