The annual Perseid meteor shower lights up the night sky. The Perseid meteor shower is considered one of the best annual meteor showers. It reaches its peak in mid-August. Meteor showers happen when the Earth moves through fields of debris floating around in space. The Perseids come from the comet Swift-Tuttle, a big ball of ice and rock that sheds pieces of dusty debris as it orbits around the sun. Join us live from China and South Korea for the stargazing spectacle of the Perseid.
