The telescope is so sensitive that its sunshield must protect it not only from the sun's heat but also from the heat of the Earth and moon.Webb is often described as Hubble's replacement or successor. Instead, it will actually orbit the sun at a distance of 1 million miles from our planet. Webb will not be in orbit around the Earth at all. Hubble operates in low Earth orbit at an altitude of around 340 miles. The two telescopes will also be in different locations in space. Hubble, without that sunshield, is about 14 feet in diameter and 43.5 feet long. The sunshield is about the size of a tennis court, 69.5 feet by 46.5 feet. The whole unit will also be bigger than Hubble, thanks to its huge sunshield that will protect Webb from heating up too much from sun exposure. ![]() Its mirror is about 21.3 feet in diameter-much larger than Hubble's mirror, which is 7.8 feet in diameter. This is the type of light that is given off by the most distant objects in space.Īt the heart of Webb's technological leap over Hubble is its enormous mirror, which it uses to capture the light from the most faint and distant parts of the universe. While the Hubble telescope primarily looks at optical and UV light, Webb will primarily look at infrared light. The way the telescopes see the universe is also different. It also means Webb will be able to look for the formation of some of the first galaxies that have so far been unobserved. ![]() The James Webb Telescope is more sensitive and is capable of longer wavelength coverage than Hubble, meaning it will be able to look further away-that is, further back in time-than Hubble. But Webb will be even better suited for peering into deep space than its predecessor. The Hubble Space Telescope has provided us with some of the most stunning images of the cosmos since it began operating in the early '90s. Twenty years of my life will all come down to that moment." Webb versus Hubble Mark Voyton, Webb observatory integration and test manager at NASA's Goddard Space Flight Center, said in a NASA press release on Thursday: "To me, launching Webb will be a significant life event-I'll be elated of course when this is successful, but it will also be a time of deep personal introspection. NASA thinks Webb's first scientific operations will start around half a year after launch and will become the space agency's flagship astronomical observation tool. It will then begin to power up and calibrate itself before peering into deep space. Once Webb launches it will take a month to fly to its orbital location, around a million miles from Earth, and slowly unfold from its current compact size.
