Why would the James Webb Telescope be better than the Hubble Space Telescope?
To discern the universe’s first, faint stars, Webb requires the largest mirror ever launched for astronomy. The mirror spans more than 21 feet (6.5 meters), yet is lighter than Hubble’s, which is 8 feet (2.4 meters) across. That’s because Webb’s mirror is made of beryllium, a strong but lightweight metal.

Why did the James Webb Telescope take so long?
But once the telescope is in space, there’s still a long way to go. Because JWST is so massive, it must fly to space folded up. Once in space, it will undergo a complex unfurling process that will take up to two weeks to complete.
How much better will the James Webb Space Telescope be?
“The James Webb Space Telescope instruments are a factor 10 to 100 [times] better than anything previously available,” Randy Kimble, JWST project scientist for integration, test and commissioning at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, told Space.com.
Why was the Kepler telescope launched into space?
The Kepler space telescope was a space telescope launched by NASA to discover Earth-size planets orbiting other stars. Named after astronomer Johannes Kepler, the spacecraft was launched on March 7, 2009, into an Earth-trailing heliocentric orbit. Only planets whose orbits are seen edge-on from Earth could be detected.
What to expect from James Webb Space Telescope?
The James Webb Space Telescope, also called Webb or JWST, is a large, space-based observatory, optimized for infrared wavelengths, which will complement and extend the discoveries of the Hubble Space Telescope. It launches in 2021. It will cover longer wavelengths of light than Hubble and will have greatly improved sensitivity.
When is James Webb launch?
James Webb will now launch in 2020. Launching a project of this size and scope will be an amazing achievement, but it is not without its challenges. Each part of the observatory must undergo rigorous testing, often both separately and once integrated into the whole, before it can be considered fit for launch.
How far away will the James Webb telescope be from Earth?
The James Webb Telescope will not be orbiting around the Earth, but the Sun, at a distance of 1.5 million kilometers or 1 million miles from the Earth.
When will JWST launch?
NASA ’s James Webb Space Telescope (JWST), earlier scheduled for launch in October 2018, will now take at least another 6 months before it succeeds Hubble Space Telescope as the most powerful eye in the sky. JWST will now launch between March and June 2019, NASA announced Thursday.
