Telescope

The largest telescope ever sent into space, Webb will open up new horizons for infrared astronomy with its innovative design and cutting-edge technology.

Webb's ambitious design tackles the two main challenges for an infrared telescope: it has to have a large mirror in order to best capture long infrared wavelengths; it also has to be kept cold, in order to keep unwanted sources of infrared light from interfering with the emissions it attempts to detect.

Webb will be stationed at the second Sun-Earth Lagrange Point, an orbit beyond the Moon, further than humans have ever travelled. Webb's giant sunshield will protect it from stray heat and light, while its large mirror enables it to effectively capture infrared light, bringing us the clearest picture ever of space objects that emit this invisible radiation beyond the red end of the visible spectrum— early galaxies, infant stars, clouds of gas and dust, and much more.

With groundbreaking design and technology, the Webb Telescope will breach the veil of the unseen universe, building on the Hubble Telescope's historic exploration of the cosmos.
