Where do the meteor showers come from
If you see a meteor shower, what you usually see are the remains of an icy comet crashing into the Earth’s atmosphere. Comets are like dirty snowballs: when they travel through the solar system, they leave behind a dusty trail of rocks and ice that lasts in space long after they leave. As the Earth passes through these waterfalls of comet waste, the pieces of debris – which can be as small as grains of sand – pierce the sky at such a speed that they burst, creating a celestial fireworks.
