Radio Astronomy Observing the Invisible Universe

About this item

• For a few hundred thousand years, we used our eyes as our primary astronomical tool. But it all changed in the 1930s when a young engineer named Karl Jansky detected radiation below the visible part of the spectrum emanating from an astronomical object - and radio astronomy was born. Radio Astronomy: Observing the Invisible Universe takes you on a thrilling journey through astounding discoveries with Felix J. Lockman, Ph.D., of the Green Bank Observatory as your guide. You’ll learn how astronomers used radio energy, some emitted from hydrogen and other atoms, to discover Jupiter’s radiation belts, Sagittarius A and the black hole at the center of the Milky Way, dark matter, neutron stars, pulsars, giant molecular clouds, and complex organic molecules in interstellar space. Learn about the principles of radio telescopes - collecting, focusing, amplifying, and analyzing radio waves - Rated 3.8 out of 5.
