James Webb Space Telescope: Largest Telescope of Earth

 James Webb Space Telescope

The James Webb Space Telescope is the largest, most powerful space telescope ever built. It has been built by NASA. It will allow scientists to look what our universe was like about 200 million years after the Big Bang. The telescope will be able to capture images of some of the first galaxies ever formed. It will also be able to look inside dust clouds to see where new stars and planets are forming and examine the atmosphere of planets orbiting other stars.

Size of James Webb Space Telescope

How big is James Webb Space Telescope? Well the answer is it is as tall a 3-story building and as long as a tennis court. It is so big that it has to fold origami-style to fit inside the rocket to launch.

Features of James Webb Space Telescope:

• It can see through dust clouds - With the help of Infrared Radiation the telescope see the universe in light that is invisible to human eyes.
• It has hat like structure at top - Just like we wear a cap or hat to block the sun from our eyes. Web has a sunshield to protect its instruments and mirrors.
• It has giant gold coated mirrors to see the universe.
• It will be hunting for signs of life on other planets.

James Webb Space Telescope was launched on 25 December 2021.

James Webb Space Telescope First Images released

NASA's James Webb Space Telescope, a partnership with European space Agency (ESA) and the Canadian Space Agency has also released the the set of first images sent by the telescope. President of America, Joe Biden revealed the first Webb Image.

James Webb Space Telescope vs Hubble Space Telescope

James Webb often gets called the replacement for Hubble, but NASA prefers to call it a successor. Webb is not replacement of Hubble. The capability of Webb and Hubble Telescope are not identical. Webb is looking at the Universe, with the help of Infrared, while Hubble was primarily at optical and ultraviolet wavelength.

Webb has a much bigger mirror than Hubble. It has large light collecting area means that James Webb Telescope can peer farther back into the time than Hubble Telescope is capable of doing. Even Hubble is in very close orbit around the earth, while Webb will be 1.5 million kilometers away.

Hubble Space Telescope

The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency.

The Hubble Space Telescope was launched on 24 April 1990 in the space shuttle Discovery. Hubble Telescope has revealed properties of space and time that for most of human history were only probed in the imaginations of scientists and philosophers.

National Aeronautics and Space Administration (NASA)

The Nationa Aeronautics and Space Administration is America's civil space program and the global leader in space exploration. It has 20 centers and facilities across the country and the only National Laboratory in Space. NASA conducts research, testing and development to advance aeronautics, including electric propulsion and supersonic flight.
