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.
