Discovering Earth: science meets art

Join planetary geologist Dr Joe Michalski and Otherworlds artist Michael Benson as they explain how space exploration sheds light on the delicate beauty of life on Earth.

Joe uses infrared remote sensing data to unlock the secrets of early life on Earth held in satellite images of volcanic Mars.

He believes that understanding life on Earth is impossible without exploring other planets. Without data from Mars, we would not be able to understand the first billion years of Earth's geological past.

But while scientists examine the data for facts and evidence, Michael searches for a different reward: beauty.
