The Hubble Space Telescope
launched in 1990. It is named after the American astronomer who
found our universe was expanding. Ninety years on, with much better
kit, Hubble’s ideas still hold. The question is how fast are we
inflating? This is the Hubble tension and Prof Geraint Lewis leads
Dr Karl through the deep space discussion.
