Millions of stars are travelling about in space. A few form groups which travel together, but most of them travel alone.

And they travel through a universe which is so large that one star seldom comes near to another. For the most important part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbour. From this it is easy to understand why a star seldom finds another anywhere near it.

We believe, however, that some two thousand million years ago, another star wandering(漫游) through space, happened to come near our sun just as the sun and the moon raised its tides(潮汐) on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; A large tidal(潮汐的) wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and thrown off small parts of itself into space.

These small pieces have been going round the sun ever since. They are the planets.

Is there something strange high up in the world’s tallest mountains? If so, is it a big bear? Is it a monkey? Or is it a kind of man?

No one knows this mystery（谜）has puzzled the world for years.

In 1887, a mountain climber found large footprints（脚印）in the snow. They looked like the footprints of a very large man. But men don’t walk without shoes in the snow!

In 1906, another climber saw more than footprints. Far off, he saw a very large animal standing on two legs. When he watched, it ran very quickly.

Fifteen years later, newspaper had new stories about the “something”. A mountain climber said he had seen the “Snowman” walk slowly across the snow, far below him. He said it looked like a very large man.

From then on, more and more people had stories to tell. But not until 1951 did a mountain climber bring back pictures of large footprints. The pictures showed clearly that the Snowman walked on two legs. So it was not a bear or a monkey? Could it be an ape man? The mystery grew! And the mystery keeps growing. Somebody we may find out just what it is that makes the large footprints.
