How Comet Got His Tail A solitary rock roamed through the cold gloom of space. It slowly moved through space with a feeling of sadness. In the large and beautiful galaxy, it was only a tiny rock. It felt like an as small as an atom. On its journeys, it encountered many amazing objects. It flew by beautiful moons that were covered with dust. " Why can't I be as beautiful as them?" it thought. The rock passed a large planet. The sphere was hundreds of times larger than the breadth of the small rock. " Why can't I be as large as that?" it wondered. The rock was filled with despair. It was surrounded by beauty and greatness, yet it was just a small and ugly fragment of rock. One day, it approached the area of a bright star. " What's wrong?" the star asked. " Oh, I wish I had a higher status in the galaxy. All the other objects are so beautiful and large, " the rock replied. " But I'm just an ugly rock. " The star considered the problem. At last, it said, " You don't have to worry anymore. I think I can help. " The star radiated its light brighter and hotter than it had ever done before. " Come a little closer, " the star said to the rock. The rock drifted closer to the star. Suddenly, the ice that was in the rock's tiny holes melted and became gas. Then, the gas came out behind the comet to form a brilliant tail. The tail shone with all the colors of the spectrum. The little rock had become a beautiful comet. It looked so amazing. It realized that the star helped it change its appearance. " Thank you, " the comet said and then flew away with its new beautiful tail following behind it like a giant cape.
