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.
