James Webb Space Telescope
Webb is the premier observatory of the next decade, serving thousands of astronomers worldwide. It studies every phase in the history of our Universe.
Key Facts
Premiere Telescope of Next Decade
extending the tantalizing discoveries of the Hubble Space Telescope.
Folding Design
So big it has to fold origami-style to fit in the rocket and will unfold like a “Transformer” in space.
1.5 Million km
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
iIt will peer back in time over 13.5 billion years to see the first galaxies born after the Big Bang.in the ISS.

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).
