Designed to answer the biggest questions in the Universe.

THE SCIENCE

Spotting the very first stars and galaxies, seeing stars and planets forming, 'sniffing' the air around alien worlds - the James Webb Space Telescope was built to do amazing things.

The biggest telescope in space and a monumental feat of engineering.

THE TECHNOLOGY

The most complex telescope ever flown, the James Webb Space Telescope will travel a million miles from Earth, unfold to the size of a tennis-court, and detect invisible light. And that’s just the beginning.

Built by people around the world, and around the corner.

THE PEOPLE

UK scientists and engineers working on the James Webb Space Telescope are part of a global team. Many hundreds of people from over a dozen nations have worked together to design, build and use the telescope.
