James Webb Space Telescope – JWST – World’s most Powerful | NASA

Are you interested to know about the world’s most powerful telescope? We have added all the James Webb Space (JWST) Telescope details. It is one of the interesting topics to learn about the NASA new telescope and other details related to the telescope. We all know about the UPSC exam syllabus, and it is the toughest exam because of the syllabus of the exam. In our earlier article, we discussed the various topics that are important for the exam. Further, the article let us learn more about the NASA new telescope James Webb Space Telescope. Let’s begin and learn more.

Introduction

To begin with, the James Webb Space Telescope is scheduled to be rocket into orbit later in the year 2021. For years, this telescope has been in the making. Further, the European Space Agency  (ESA)  and the Canadian Space Agency (CSA) collaborated. Further, it is the world’s most powerful telescope. Therefore, it is exciting to learn more about the telescope and why it is essential for the IAS exam. Therefore, we have added all important details about the NASA new telescope as points for the exam below.

There are many things to be studied for the IAS exam and get the best scores in the exam, and one must cover all essential topics. In the IAS exam, there are three rounds, and one needs to clear all three rounds. In the first stage, questions will be objective type of questions, and in the second round, questions will be descriptive type. Therefore, it is important for both rounds. Let us know about the world’s most powerful telescope JWST NASA’s new telescope. While reading the article, make sure you have noted down all essential points to help you with the exam. Further, try to revise to remember things well.

Telescope

We know the meaning of telescopes and their uses. According to the definition, it is an optical instrument that uses lenses and curved mirrors. It is used to observe distant objects or various devices used to observe distant objects by their emission, absorption. Further, the first telescope, a practical telescope, refracted with glass lenses.

Further, it is essential to know why telescopes are important in space. Then, the thermal turbulence of the Earth’s atmosphere hinders telescopic observation of the universe. Besides, by placing the telescopes in the rocket, one cab observes stars twinkle, light from the stellar objects are absorbed by the thick atmosphere, and part of the spectrum. Telescopes in space avoid the atmospheric disturbance and offer us a clear, sharp, and more profound vision of the farthest reaches of the universe.

James Webb Space Telescope

The Webb Telescope is the Hubble Space Telescope’s replacement. Further, it launched on an Ariane 5 rocket, with 82 successful missions between April 2003 and December 2017. Further, this telescope has longer wavelengths enable to look much closer to the beginning of time. Besides, it is known as the successor to the Hubble Space Telescope, which was launched in 1990.

Further, this telescope is expected to discover various secrets of the universe, mainly that are related to the creation of stars & galaxies in the early period — the first few hundred million years — after the Big Bang. These kinds of telescopes are often named time machines as they have the ability to view very faraway objects. Besides, this telescope is much more powerful, and it has the ability to look in the infrared spectrum. It allows it to go deeper into the universe and see-through obstacles like gas clouds. Besides, what telescopes see are images of stars and galaxies are million years ago.

Goal

The goal is to search for the first galaxies formed after the Big Bang. Further, to observe the formation of stars from the first stages to the formation of planetary systems. Besides, to measure the physical and chemical properties of planetary systems, which includes the Solar System, and observe the potential for life in those systems.

Features

• It is one of the most powerful telescopes launched by NASA. Further, the main features include a primary mirror that is made of 18 seperate segments that help to unfold and adjust to shape aftrer launch.
• Further, the biggest feature is atennis court sized and five layer sunshield that  attenuates heat from the Sun more than a million times.
• It comes with cryocooler for cooling the mid-infrared detectors of other instruments. 
• The wavelength is visible, near infrared, mid infrared ((0.6-28.5 micrometres) and Orbiting the Sun around the second Lagrange point (L2).

Cost

NASA invested $8.8 billion in Webb’s design and engineering to build this telescope. Further, it will invest  $860 million over the next 5 years to keep the mission running. Therefore, it totals $9.7 billion in the United States. Besides, EU Space Agency contributed €700 million, and the Canadian Space Agency (CSA) also contributed over CA$200 million. These all add up to more than $10 billion.

Objectives and Functions

Further, this telescope will look deeper into the cosmos – and thus further back in time than is possible with Hubble. Besides, it will be with a much bigger mirror, 6.5 m in diameter versus 2.4 m, and it is with infrared. Further, it will detect the light from the very first population of stars in the Universe.

What makes Webb Space Telescope different?

Let us now know how it is different from the Hubble telescope.

In the first place, with respect to the wavelength, the Webb telescope has four scientific instruments to know primarily in the infrared range and provide coverage from 0.6 to 28 microns. besides, the instruments on Hubble mainly focus on the ultraviolet and visible parts of the spectrum. Therefore, it is from the range of 0.8 to 2.5 microns.

Further, with size, Webb’s primary mirror is of a diameter of 6.5 meters. Besides, it carries a large sun shield measuring about 22 meters by 12 meters. The Hubble’s mirror was much smaller and 2.4 meters in diameter.

Webb will not orbit the Earth, and it will orbit the sun at about 1.5 million kilometers away from Earth. Hubble rotates around the earth at an altitude of about 570 km.

Hubble studied the toddler stage of galaxies, and Webb can study the baby stage too.

Launch Date

James Webb Space Telescope will launch an Ariane 5 ECA rocket from French Guiana in South America. Further, the Ariane 5 is believed to be one of the most reliable launch vehicles. So then, EU Space Agency decided to take on the burden of putting Webb into space as a project partner. Further, the rocket will launch roughly one million 1.6 kilometers from the earth. It has the ability to make observations without the occasional obscuring effects that it would encounter if it were closer to our earth.
