How radio telescopes show us unseen galaxies | Natasha Hurley-Walker

Our universe is strange, wonderful and vast, says astronomer Natasha Hurley-Walker. A spaceship can’t carry you into its depths (yet) — but a radio telescope can. In this mesmerizing TED talk, Hurley-Walker shows how she probes the mysteries of the universe using special technology that reveals light spectrums we can’t see.

Natasha Hurley-Walker helped with the commissioning of the Murchison Widefield Array (MWA), the SKA-low precursor in Western Australia and recently undertook a two-month fellowship at the Square Kilometre Array (SKA) Headquarters at Jodrell Bank in the UK to work with the science team there on expanding this idea into building the first surveys with the future SKA-low telescope. The SKA—a global project with twelve member countries—aims to answer fundamental questions about the origin and evolution of the Universe.
