SPRINGER PRAXIS BOOKS ASTRONOMICAL DISCOVERIE...

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.
