NASA's Touch the Invisible Sky Audio Podcasts

Multi-wavelength astronomy - the study of the universe at wavelengths beyond the visible, has revolutionized our understanding and appreciation of the cosmos. Hubble, Chandra, and Spitzer are examples of powerful, space-based telescopes that complement each other in their observations spanning the electromagnetic spectrum. NASA's Braille book "Touch the Invisible Sky" presents the first printed introduction to modern, multi-wavelength astronomy studies to the sight disabled community.
