Jelly-Comets

Comets are the most beautiful and exciting sights in the sky. They are made more mysterious by their unpredicitability, leading people in the past to think that they were either good or evil.

Over hundreds of years ago comets were thought to be within our atmosphere. Then in 1577, Danish astronomer Tycho Brahe worked out the distance to a comet and showed that they came from beyond the planets, and rounded the sun before returning to deep space.
