“How Radio Telescopes Show Us Unseen Galaxies” (TED)

TED.com just published a short talk given in October of last year at TEDxPerth by Astronomer Natasha Hurley-Walker about a large radio telescope array she works at Murchison Radio Astronomy Observatory in the Western Australian desert. This may be of particular interest to Prof. Kardel’s Astronomy 100 students, who recently started learning about the light spectrum and various types of telescopes.
