Would you like to live forever? Only 20% of people say yes.

Professor Miroslav Filipović - astrophysicist at Western Sydney University and one of the rare scientists to have observed Earth from above its atmosphere aboard NASA's SOFIA mission - reveals the invisible force quietly placing an expiry date on every human life: cosmic rays. His team also discovered a particle carrying more energy than a thousand trillion light bulbs, and a perfectly circular mystery object in space that had the world whispering "aliens."

From the science of ageing to NASA's return to the Moon, the US-China space race, and Australia's hidden role in global astrophysics - this is where health meets the cosmos.
