"Twenty-Five Astronomical Observations That Changed the World" takes twenty-five journeys through space, back in time and into human history. We begin with the simplest sight of the Tycho Crater on the Moon, through a repeat of Galileo's observations of Jupiter's moons, and then move out towards the nebulae, stars, and galaxies. The astronomical observations repeat the original groundbreaking discoveries that have changed our understanding of science and ourselves.
This title contains graded observing challenges from the straightforward to the more difficult (in chapter order). It offers clear observing tips and lots of practical help, presuming no prior in-depth knowledge of equipment. Binoculars and/or a small astronomical telescope are all that is required for most of the observations.
Secondly, it explores for each observation the science of what is seen, adding to the knowledge and enjoyment of amateur astronomers and offering lots of reading for the cloudy nights when there is not a star in view.
Thirdly, the book puts the amateur astronomers' observations into a wider perspective. "Twenty-Five Astronomical Observations That Changed the World" makes the observer part of that great story of discovery.
Each chapter, each observing challenge, shows how to observe and then how to look with understanding. The projects begin with practicalities: where the object is, how best is it observed and with what appropriate equipment (usually a small-to-medium aperture amateur telescope, binoculars, even the naked eye).
"Twenty-Five Astronomical Observations that Changed the World" guides even the inexperienced amateur astronomer - beginners can use the book - around a variety of night-sky objects, and reminds the more experienced how they can best be seen. These practical observations put us in contact with all the history and culture surrounding them: through scientific speculation and literature to those first fuzzy images made in 1959 by the Russian space probe Luna 3.
Human history is also the record of our fascination with the sky, and to look upwards is to follow in the steps of such greats as Galileo and Newton. What they and others once saw in the heavens for the first time, amateur astronomers can discover anew using this guide to twenty-five of the greatest journeys through space.
Starting with our most visible companion the Moon, each chapter offers a step-by-step walk-through of famous astronomical observations from the history of science. Beginning with the easiest targets, sometimes even accessible with the naked eye, the challenges become progressively more difficult. Beginner astronomers and more experienced hobbyists alike can reacquaint themselves with the wonders of our fellow planets and even reach far beyond our own solar system to touch on such incredible phenomena as the birth of new stars in nebula systems and the deceptive nothingness of black holes. The would-be astronaut can spy the International Space Station in orbit with binoculars or the doomsday prophet can search for new comets. Along the way, easily digestible mini-lessons inform the reader on the initial discovery of then-new celestial bodies and subsequent advances in our understanding of the cosmos.
Relying only on binoculars or small astronomical telescopes for most of the observations, and including background on the science of each phenomenon, this exploration of the skies is easy to follow and packed with useful information and fun tidbits. These practical observations put us in contact with all the history and culture surrounding them: through scientific speculation and literature to those first fuzzy images made in 1959 by the Russian space probe Luna 3.
