3. Beyond the Pale Blue Dot

How to explore space, without leaving earth.

Astrophysicist Emma Chapman takes us on an electrifying voyage through the cosmos using one of the most powerful, yet overlooked, tools in science: the radio wave. Chapman reveals how these invisible messengers glide through space, bounce off planets, tunnel through clouds and slip past galactic dust - carrying secrets of the universe that no other kind of light can uncover.

A celebration of human ingenuity and cosmic curiosity, The Radio Universe reveals that the true frontier of space isn't 'out there' - it's humming quietly all around us, waiting to be heard.
