This book is for the aging amateur astronomy population, including newcomers to astronomy in their retirement and hobbyists who loved peering through a telescope as a child. Whether a novice or an experienced observer, the practice of astronomy differs over the years. This guide will extend the enjoyment of astronomy well into the Golden Years by addressing topics such as eye and overall health issues, recommendations on telescope equipment, and astronomy-related social activities especially suited for seniors. Many Baby-Boomers reaching retirement age are seeking new activities, and amateur astronomy is a perfect fit as a leisure time activity. Established backyard astronomers who began their love of astronomy in their youth, meanwhile, may face many physical and mental challenges in continuing their lifelong hobby as they age beyond their 55th birthdays. That perfect telescope purchased when they were thirty years old now suddenly at sixty years old feels like an immovable object in the living room. The 20/20 eyesight has given way to reading glasses or bifocals. Treasured eyepieces feel all wrong. Growing old is a natural process of life, but astronomy is timeless. With a little knowledge and some lifestyle adjustments, older astronomers can still enjoy backyard observing well into their seventies, eighties and even into their nineties.

Ignite their passion for exploring the night sky―the astronomer's guidebook for kids ages 7 to 13 “No matter how many times you’ve orbited the Sun, Astronomy for Kids is really for kids of all ages. Dr. Betts shows you how to become an astronomer―an observer of the stars. With this book, you can know the cosmos and your place within it. Read on, walk out, and look up!”―Bill Nye, science educator, author, and CEO of The Planetary Society One of the coolest things about outer space is that anyone can explore it. All you have to do is go outside and look up! Using plain sight, binoculars, or a small telescope, Astronomy for Kids shows stargazers how easy it is to explore space, just by stepping outside. With this book as their guide to the northern hemisphere, kids will learn to find and name amazing objects in the night sky. Fully illustrated with fun facts throughout, kids can point out sights to friends and family, saying things like, “that’s Jupiter,” and, “those stars are the constellation Cygnus the Swan,” and maybe even, “that group of stars doesn’t have a name but I think it looks like my dog getting belly rubs.” From the Milky Way Galaxy to Mars to the Moon’s craters and mountains―Astronomy for Kids helps young astronomers discover important parts of our solar system, with: 30 sights for the naked eye (yes, 30!) objects to see without any equipment, including Orion’s Belt, the Big Dipper, Mars, and even the International Space Station. 25 sights magnified with binoculars or a basic telescope to make objects in the sky easier to find and explore. Plus, buying tips and usage tricks to get the most out of astronomy equipment. Clear illustrations that show kids where to look and what they can expect to see. Like all big things, outer space is something you have to see to believe. Astronomy for Kids teaches kids that planets, shooting stars, constellations, and meteor showers are not only in books―but right above them.

Mahabharata says, “Ordinary men see through their eyes, cows see by smell, kings by spies, and the learned men see through the scriptural knowledge. We think of the world as we do. In fact, the world is different than the ways we see it. Most of our paradigms are inaccurate because we do not have all of the information. We think we do, but we don’t. When we receive additional or new information, it often causes us to rethink and change our paradigm. Challenge your assumptions about yourself, others, situations, and things. The world transforms as you transform yourself. The key to personal effectiveness is to change our paradigms, our assumptions, and the way we see the world.

Excerpt from Practical Astronomy When we cast our eyes to the heavens on any clear and, by preference, moonless night, our attention is attracted by apparently innumerable points o light, of all degrees of brightness. These are the stars, which in all ages have drawn to themselves the attention of mankind. Mr. E. W. Maunder, in a previous volume of this series, has shown how mans attention was first directed to the heavenly bodies, and how the mere recognition of the phases of the Moon, the varying positions of the planets and the seasonal changes of the stars has developed stage by stage into the science of astronomy as we know it at the present day. Perhaps of all the sciences, modern astronomy is the most awe-inspiring, the most wonderful, the most instructive. The average man reads of the marvels which the telescope and spectroscope reveal, of the great depths and spaces, the rapid velocities, the eternal working of evolution, and he wonders. He has little or no knowledge of the methods used by the astronomers in ascertaining the facts of the science; and he is not familiar with the stars or constellations.
