BBC - Secrets of Size Atoms to Supergalaxies (2022) (2)

Jim Al-Khalili explores the vast range of size in the universe, from tiny atoms to gigantic, interconnected galaxies.

Part 1 Going Small

Jim Al-Khalili explores the universe at the smallest scales, from tiny atoms to vast galaxies. The first episode examines objects too small to glimpse with the naked eye, and reveals how nanomaterials such as graphene are revolutionising engineering, medicine, computing, electronics and environmental science.

Part 2 Going Big

Jim Al-Khalili explores the largest known cosmic structures, including, a vast cloud of solar plasma which surrounds and protects the solar system, the black hole at the centre of the Milky Way, which emits the lowest note ever heard in the cosmos, and the giant arc, a collection of galaxies which spans more than three per cent of the observable universe.
