With a massive mirror and the ability to see light at the infrared part of the spectrum, it can peer back billions of years through history to capture the faint, red-shifted light from the very beginning of the universe.Jan 10, 2022
What is special about the James Webb 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 will have longer wavelength coverage and greatly improved sensitivity.
How is the James Webb telescope better?
Webb will have significantly larger field of view than the NICMOS camera on Hubble (covering more than ~15 times the area) and significantly better spatial resolution than is available with the infrared Spitzer Space Telescope.

Is the James Webb telescope better than Hubble?
The James Webb Telescope was launched just last month, in December 2021, and is designed to see things 10-100 times fainter than Hubble. Klaus Pontoppidan, before the launch of Webb, said during a news conference that the images taken by Webb will be better than that of Hubble.
Is Webb telescope visible from Earth?
New York: The James Webb Telescope of the US space agency NASA has been visible from Earth for the first time. This telescope is currently 1.6 million kilometers away from Earth. In the first picture, the James Webb Telescope looks like a star.
What James Webb telescope will see?
According to NASA, the James Webb Space Telescope will focus on four main areas: first light in the universe, assembly of galaxies in the early universe, birth of stars and protoplanetary systems, and planets (including the origins of life.)
How long will James Webb last?
In simple words, less fuel than originally planned for is needed to correct Webb's trajectory toward its final orbit around the L2 (second Lagrange point). As a result, Webb has a reserve of fuel to keep it operational for 10 years or more.
How far can Webb telescope see?
According to NASA, the Webb telescope is so sensitive to infrared light, it would be able to detect even the slight heat of a bumblebee at the distance of the moon. Technically, it could also see details as small as a U.S. penny at a distance of about 25 miles.
What is the status of the James Webb telescope?
Webb is currently at its observing spot, Lagrange point 2 (L2), nearly 1 million miles (1.6 million km). It is the largest and most powerful space telescope ever launched.
