James Webb Space Telescope
Webb is the largest and most complex observatory ever sent to space, serving thousands of astronomers worldwide.
Key Facts
Largest Most Complex Space Telescope
Webb’s innovative design tackles the key challenges for an infrared telescope
Folding Design
So big it had to fold origami-style to fit in the rocket and unfolded like a “Transformer” in space.
1.5 Million km from Earth
Webb orbits the Sun 1.5 million kilometers from the Earth. (Hubble orbits 560 kilometers above the Earth.)
SPF 1 Million
Webb has a 5-layer sunshield that protects the telescope from the infrared radiation of the Sun, Earth, and Moon; like having sun protection of SPF 1 million.
Unprecedented Sensitivity
Webb's sensitiviy allows it to peer back in time over 13.5 billion years to see the first galaxies born after the Big Bang.

The Webb Mission
Webb is the largest and most complex observatory ever sent to space, serving thousands of astronomers worldwide. It studies every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.

The International Webb Team
Webb is for the world, and from the world. Thousands of skilled scientists, engineers and technicians from 14 countries (and more than 29 U.S. states, and Washington, D.C.) contributed to the design, build, test, integration, launch, commissioning and operations of Webb. It is a joint NASA/ESA/CSA mission. Assembly and testing of the mirror and instruments occurred at NASA Goddard (GSFC).
