A bright, glowing deep-space comet zooms rapidly through the starry expanse, displaying a long, beautifully sweeping tail of icy debris.
Meet Cosmo, a cheerful comet with a very big job! He loves to travel across the vast, dark ocean of space. Every few thousand years, he zooms past planets and waves to the distant sun. In this picture, Cosmo is moving super fast! Can you see the glowing circle at the front? That is his head, called a nucleus. Even though his tail looks like a streak of fire, a comet is actually made of ice, dust, and rock. Because of this, scientists often call them "dirty snowballs!"
