ASTRONOMERS' OBSERVING GUIDES provide up-to-date information for amateur astronomers who want to know all about what it is they are observing. This is the basis of the first part of the book. The second part details observing techniques for practical astronomers, working with a range of different instruments. Have you ever been on the beach at night, watching the sky overhead, and seen streaks of light against the background of stars? Though many people still refer to these as shooting stars, they are, of course, not stars. They are meteors small chunks of rock and ice debris from disintegrating comets that are careening through our Solar System and sometimes enter Earth's atmosphere. Most are so small that they burn up as they enter the atmosphere. These are called meteors. In a meteor shower, many meteors can be seen streaking across the sky in a short time. A few meteors make it through intact and descend to Earth as meteorites. Watching these beautiful streaks of light in the sky can be an exciting pastime, and it can result in some important science. Robert Lunsford explains what meteors are, where they come from, and what happens to them as they whiz through space and enter our atmosphere. He tells how to observe meteors and meteor showers, what equipment to use, what you should look for, where you should look, and much more. Armed with the information in this book and with very little effort and equipment, you can begin your regular search of the heavens right now and join the ranks of those who have made this rewarding pastime a lifetime hobby.

We all know that Earth's population is growing at an alarming rate, and vital resources are becoming scarce. There simply isn't enough space to grow the food the bulging human populations will need in the future. An energy crisis is also upon us. What happens when the oil runs out or becomes too costly to support us in the lifestyles to which we've become accustomed? What do we do? There are no easy solutions. Planned population growth would certainly be a possible solution, but there are probably already too many mouths too feed, and few nations would be willing to pass or enforce laws limiting their country's birth rate. Some scientists have suggested the answer lies in humankind's spacefaring nature and fantastic engineering capabilities. We know that there are other terrestrial bodies in our Solar System that share some features with Earth. Can they be made habitable, or at least be used to grow food or supply energy to Earth's expanding populations? What would it take? Which of those bodies are our best hope? Can we create an atmosphere where there is none or change a poisonous atmosphere to one we can breathe? These and other questions concerning modern-day realities and the future possibilities of terraforming the science of making of new worlds (even extrasolar ones) habitable for humans are tackled in this engrossing and revealing study by Martin Beech.
