Webb’s design began even before the Hubble Telescope was launched. It took many years to build.

Webb helps us learn about the universe from the Big Bang to how stars and planets form.

The Hubble Space Telescope has made many discoveries, like finding dark energy and seeing other planets' atmospheres.

Hubble has helped us study planets around other stars and discover dark energy.

Both Hubble and Webb are reflecting telescopes. They use curved mirrors instead of lenses to collect and "bend" light to their various instruments.

Webb’s 6.5-metre mirror is much larger than Hubble’s 2.4-metre mirror, letting it collect over six times more light.
