What Is Special About James Webb Space Telescope?

NASA's ambitious scientific project is the James Webb Space Telescope. In order to further advance human understanding regarding the genesis of the earliest galaxies, Webb will draw on the heritage of earlier space-based observatories.

The James Webb Space Telescope(JWST), NASA's next flagship infrared observatory, was developed in partnership with ESA and CSA and successfully launched on December 25, 2021. After deploying in space and alignment and calibration of the mirrors and instruments, JWST will be ready for science operations in the summer of 2022.
Accessible to the worldwide scientific community, it will allow scientists to observe galaxy evolution, the formation of stars and planets, exoplanetary systems, and our own solar system in ways never before possible.

James Webb Vs. Hubble

Today, the James Webb Telescope, which was dubbed "NASA's second kid" last year, began its orbit around Lagrange point 2, or L2, which is nearly a million miles from Earth. The mighty space telescope will follow Earth's orbit around the Sun.
The Hubble telescope is now around 340 miles away from the earth. In April 1990, Hubble was put into low-Earth orbit. The James Webb Telescope, which was only just launched in December 2021, is intended to detect objects that are 10-100 times fainter than those seen by Hubble.
Before Webb's launch, Klaus Pontoppidan said during a press conference that the photographs captured by Webb would be superior to those of Hubble. Additionally, Webb can detect infrared light since it is intended to do so, producing extraordinary and beautiful photos. On the other hand, Hubble can see light in the optical and ultraviolet ranges.
The Hubble is around 340 miles distant, whereas the Webb telescope is about a million miles away.
Webb is anticipated to travel beyond Hubble's field of view and see the light from the early stars and galaxies in the cosmos, revealing what the stars were like 13.7 billion years ago.

James Webb Space Telescope Instrument Check

The instrument modes for the James Webb Space Telescope are now being tested for science operations, which are scheduled to start in the middle of July.
With four state-of-the-art equipment, the $10 billion James Webb Space Telescope will be able to observe the oldest and most distant galaxies, which emerged in the early cosmos just a few hundred million years after the Big Bang and investigate their chemical makeup.
Before the telescope can start conducting science operations in the middle of July, each of these instruments' 17 science modes must be checked.

Did It Get Hit By A Meteoroid?

The primary mirror of the brand-new James Webb Space Telescope was struck by a small rock piece.
The dust-sized micrometeoroid's damage is clearly visible in the observatory's data, but it is not anticipated to have a significant impact on the mission's overall performance.
Engineers can eliminate some imparted distortion by moving the position of the problematic mirror segment, but not all of it.

When Will The Images Be Released?

The photographs will be unveiled at a live ceremony that will be broadcast on NASA TV and ESA WebTV, according to a recent announcement from the European Space Agency (ESA). The live stream will begin at 16:30 CEST, or 8 p.m. IST, and will be followed by a joint media briefing at 18:00 CEST, or 9:30 p.m. IST, at NASA's Goddard Space Center.
Although it is unclear exactly what the photos will show, they will undoubtedly show Webb's equipment's capacities and sensitivity to infrared light.

How Long Will It Take For The James Webb Telescope To Unfold?

The mirrors of the telescope must then be aligned, which should take the crew roughly three months. Then it will complete commissioning all of its instruments, making sure they are all cooled and functional. However, if all goes as planned, the telescope's first photographs should be made public in less than six months.

What Is Special About The James Webb Telescope?

The James Webb Space Telescope is an infrared observatory orbiting the Sun at a distance of around one million miles from Earth. It searches for the earliest galaxies that emerged in the early cosmos and watches stars develop planetary systems.

What Is The Current Status Of The James Webb Telescope?

Lagrange point 2 (L2), where Webb is now monitoring, is around 1 million miles away (1.6 million km). It is the biggest and most powerful telescope ever launched into orbit.
