From the dust jacket:
Is there life on Mars?
Perhaps of all the tantalizing questions about the red planet that astronomers have been trying to solve for 300 years, this is the most exciting.
Mars is the "mystery planet" of our solar system; near enough to earth to encourage investigation, and yet just far enough away to make investigation difficult.
What are its mysterious "canals"? Some astronomers have suggested that they may be gigantic waterways built by intelligent beings, and yet others believe them to be nothing more than optical illusions.
Are the dark areas that change in size, shape, and color every year really large areas of plant life, and if so, does this mean that animal life may also exist there?
Are its great polar caps thick deposits of ice, such as our own North and South Poles, or just a blanket of snow only inches deep?
The author of this book is well qualified to explore these interesting facts. He gives all the most up-to-date scientific information available and has written it in a clear and lively manner that will be enjoyed by any reader who has an interest in this subject.
