Three years ago, the world's largest and most powerful telescope was sent into space with an ambitious mission. Its task was to see the earliest galaxies and stars formed in the universe. Orbiting the Sun 1.5 million kilometres from Earth, the James Webb Space Telescope has looked back in time over 13 billion years, capturing never seen galaxies and planets. Astronomer Michael Brown from Monash University in Melbourne told Cameron Carr the telescope is changing how we see the universe.
