八月的夜空：英仙座流星雨入门指南
Every August, the night sky puts on a show. You can see many bright shooting stars. They seem to come from one point in the sky. This is the Perseid meteor shower. It is one of the most famous space events each year.
What makes these lights in the sky? Earth moves through space all the time. In August, our planet goes through a dusty part of space. That dust comes from a big space rock called a comet. The comet's name is Swift-Tuttle. When the small dust bits hit our air, they burn up. They make a fiery line that we call a shooting star.
