Description: 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 talk, Hurley-Walker shows how she probes the mysteries of the universe using special technology that reveals light spectrums we can't see.

How radio telescopes show us unseen galaxies

The universe is far more vast and mysterious than the human eye can perceive, with much of its story written in signals invisible to us. By using radio telescopes, astronomers mapped 300,000 galaxies and revealed cosmic features hidden by dust and distance. These instruments expose immense jets from black holes, remnants of exploded stars, and the radio glow of our own galaxy. New technology promises to push even further, reaching back to the universe's first moments.
