Have you seen rain in a clear sky?

This rain has no water.

It is a meteor shower.

Many lights cross the night sky.

Halley’s comet left dust in space.

A comet is an icy space rock.

Two times each year, Earth meets this dust.

The small pieces enter our air.

They get very hot and shine.

Think of walking through light rain.

You move, and drops touch your coat.

Our world moves through dust, too.

But this dust looks like falling stars.

Old dust can make new light.
