Beschreibung
You too can follow in the steps of the great astronomers such as Hipparchus, Galileo, Kepler and Hubble, who all contributed so much to our modern understanding of the cosmos. This book gives the student or
amateur astronomer the following tools to replicate some of these seminal observations from their own homes:
With your own eyes: Use your own observations and measurements to discover and confirm the phenomena of the seasons, the analemma and the equation of time, the logic behind celestial coordinates, and even the precession of the equinoxes.
With a consumer-grade digital camera: Record the changing brightness of an eclipsing binary star and show that a pulsating star changes color as it brightens and dims. Add an inexpensive diffraction grating to your camera and see the variety of spectral features in the stars, and demonstrate that the Sun’s spectrum is similar to one particular type of stellar spectrum.
With a backyard telescope: Add a CCD imager and you can measure the scale of the Solar System and the distance to a nearby star. You could even measure the distance to another galaxy and observe the cosmological redshift of the expanding universe.
Astronomical Discoveries You Can Make, Too! doesn’t just tell you about the development of astronomy; it shows you how to discover for yourself the essential features of the universe.

“This is one of the most genuinely exciting new astronomy books I’ve seen in a long time. It shows you, for example, how you can use Galileo’s method to work out the height of mountains on the moon. … The time commitment and equipment requirements for each project are well set out, and the projects are well explained. … this book a treat for the armchair astronomer, but a real treasure trove for a team of committed explorers.” (Andy Sawers, Astronomy Now, February, 2016)
