What is better about the James Webb telescope?
With a mirror almost three times wider, JWST will be able to see objects almost nine times fainter than Hubble, allowing us to peer even further into space.
What is the most important function of an astronomical telescope?
The most important functions of a telescope are (1) to collect the faint light from an astronomical source and (2) to focus all the light into a point or an image.
Why is the James Webb telescope better than Hubble?
The Webb telescope’s primary mirror is 6.5 meters in diameter, compared with Hubble’s, which is 2.4 meters, giving Webb about seven times as much light-gathering capability and thus the ability to see further into the past.
What is the main purpose of the Hubble Space Telescope?
Hubble was designed as a general purpose observatory, meant to explore the universe in visible, ultraviolet and infrared wavelengths. To date, the telescope has studied more than 40,000 cosmic objects, providing views astronomers were unable to capture from the ground.

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.
What does the James Webb Space Telescope mean?
The James Webb Space Telescope (sometimes called JWST or Webb) is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope, with longer wavelength coverage and greatly improved sensitivity.
What is the principle of Webb Telescope?
Among its goals is the study of the Universe’s first stars. In order to image these faint and distant objects, Webb was optimized to observe in the infrared. Observing in the infrared was the fundamental guiding principle in Webb’s design and influenced both the overall system architecture as well as its constituent materials.
