What is the (JWST) James Webb Space Telescope

The James Webb Space Telescope (JWST) is a space telescope designed primarily for conducting infrared astronomy. It has been launched into space as the most powerful telescope ever. Its much better infrared resolution and sensitivity will allow farther, older, or fainter objects to be seen in space than the current Hubble Space Telescope.

It is the largest, most complex and powerful space telescope ever built. The James Webb Space Telescope is a spacecraft telescope designed to explore the mysteries of space in the farthest and coldest places. The Webb Telescope will fundamentally change our understanding of the universe. It has been built as a replacement for the Hubble Telescope because it is very old.

The James Webb Space Telescope is almost ready to begin its mission. Its use is expected to enable broader investigations in the fields of astronomy and cosmology. Such as the observation of the first stars and the formation of the first galaxies, and the study of detailed atmospheric characteristics of potentially habitable exoplanets.

The Webb Space Telescope (JWST) has been progressing smoothly and even performing above expectations since its deployment by NASA. Having reached its final destination and deployed its instruments, JWST has now completed all of its tests, meaning it is perfectly focused and capable of taking pin-sharp imagery. All that is left now is to calibrate the instruments properly.

James Webb Space Telescope and Hubble Space Telescope

It is the scientific successor to the Hubble Space Telescope and the modern generation visionary, which was launched by NASA and other space agencies of the world on 25 December 2021 from the Ariane 5 rocket. It is more powerful than the Hubble telescope and provides the ability to clearly see even very distant objects in space and send them back to Earth (Earth) by taking a picture of them.

As the successor to the Hubble Space Telescope, NASA’s new and improved space observatory has several goals set for its journey into space. It will not only be used to deepen our understanding of the Milky Way, but it will also look at distant exoplanets and celestial bodies, and look for evidence of dark matter.

(JWST) The James Webb Space Telescope was launched on 25 December 2021 from Kourou, French Guiana on a European Space Agency (ESA) Ariane 5 rocket. And it entered the scheduled orbit in January 2022. As of July 2022, it is undergoing instrument mode check-out.

Once operational, it is expected to be about the beginning of July 2022, JWST aims to succeed Hubble as NASA’s flagship mission in astrophysics. NASA on Tuesday, July 12, 2022 at 10:30 a.m. EDT/usa. The first official science image release program is scheduled for.

Why is it named the James Webb Space Telescope

The telescope is named after James E. Webb, who was NASA’s administrator from 1961 to 1968 during the Mercury, Gemini and Apollo space programs.

Who is James Webb? (Who is James Webb)

James Edwin Webb was a US government official who served as the Undersecretary of State from 1949 to 1952. He was also NASA’s second appointed administrator from February 14, 1961 to October 7, 1968.

What is James Webb famous for?

James Edwin Webb served as the administrator of the US space agency NASA from February 1961 to October 1968.

Who built the James Webb Space Telescope

The American space agency NASA led the development of JWST in collaboration with the European Space Agency (ESA) and the Canadian Space Agency (CSA). Under his direction, the James Webb Space Telescope has been built by two aerospace companies, named Northrop Grumman and Ball Aerospace & Technologies.

Whose project is the James Webb Telescope?

The James Webb Space Telescope is an international collaboration between NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA).

The James Webb Space Telescope is sometimes called JWST or Webb. An orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope with longer wavelength coverage and much better sensitivity. The longer wavelength enables Webb to look very close to the beginning of time and look for the first galaxies unobserved formation, as well as inside the dust clouds where stars and new planetary systems are forming today.

How Big is the James Webb Space Telescope

Although almost twice as large (which is only 13 meters long) when compared to the Hubble telescope, JWST weighs about half that of Hubble at 6,500 kg. JWST’s gold-plated mirror has an overall diameter of 6.5m, much larger than Hubble’s 2.4m diameter plate. In total, the James Webb Space Telescope will have a wider view of about 15 times than Hubble.

How tall is the James Webb Telescope?

The Webb telescope’s sunshield dimensions are 21.2 by 14.2 meters (69.5 by 46.5 ft) and the overall observatory height is 8 meters (28 ft).

What is the size of the mirror of the James Webb Telescope? (what is the size of james webb’s mirror)
Webb’s segmented primary mirror has a diameter of 6.5 meters (21.7 ft). Each of the 18 segments is 1.32 meters (4.3 ft) across. The mirror has an area of ​​about 25 square meters (270 sq ft) and a mass of 705 kg (1,550 lb on Earth).

Webb’s primary mirror is 6.5 meters (21 ft 4 in) across; A mirror that had never been launched into space before.

Why does the James Webb Telescope need a sunshield?

In order to accurately and precisely detect faint infrared light from distant objects in the universe, the Webb telescope must be shielded from the strong infrared light emanating from near the Sun, Earth and the Moon. Five layers of sunshields block light from these nearby objects.

How does the James Webb Telescope get power?

The James Webb Telescope is powered by an on-board solar array. It also has a propulsion system to maintain the orbit and attitude of the observatory. The solar array provides 2,000 watts of electrical power for the life of the mission, and has enough propellant for at least 10 years of science operation.

How much data will the James Webb Telescope transmit each day

This telescope can downlink at least 57.2 gigabytes of recorded science data every day, with a maximum data rate of 28 megabits per second.

Can a telescope sunshield withstand the micrometeoroid effect

Sunshield layers are built with ripstops, so if a layer pierces a layer, it may not rip very far, allowing the layer to maintain structural integrity .

How telescope mirrors are aligned after launch difficulties

The primary mirror segment and secondary mirror are moved by six actuators that are attached to the back of the mirrors. The primary segments have an additional actuator at the center of the mirror to adjust their curvature. Those seven spots are adjustable to align the 18 segments of the primary mirror to each other, and accommodate the primary and secondary mirrors in fixed tertiary mirrors and devices.

How much gold was used to make the James Webb Space Telescope

A little more than 48 grams of gold is used in the Webb telescope mirror. This is equal to the mass of a golf ball, which would fill a volume the size of a marble. This gold is a thin (100 nanometer) layer of vacuum vapor deposited on each of the 18 primary mirror segments and a single secondary mirror. Gold is a highly reflective material at infrared wavelengths, which helps focus light from distant objects onto Webb’s sensitive instruments.

What is the expected lifetime of the James Webb Telescope

It is designed for science operations of at least five years, with a goal of an overall mission lifetime of more than 10 years.

(JWST) How far can be seen in space with the James Webb Telescope

Over the course of six months, the James Webb Space Telescope orbits the Sun with Earth, giving it the ability to observe almost any point in the sky. Webb’s field of connection is limited to a 50-degree swath of the celestial sphere: about 39% of the sky is potentially visible to Webb at any given time. Because James Webb must be far from objects that are hot and so close that they may interfere with the ability to see faint or faint infrared light, it cannot observe the Sun, Mercury, Venus, Earth, or the Moon. .

Where is the James Webb Space Telescope now

The James Webb Space Telescope is now in L2 orbit – its final destination, approximately 1.5 million kilometers from Earth. It is a journey that has taken almost a month to complete. You can track its progress with NASA’s Where is Webb feature. It shows not only the current distance from Earth but also the speed, temperature, how long it has been in orbit and what its next phase is.

How does the James Webb Telescope work

The James Webb Space Telescope, also known as Webb or JWST, is a high-capacity space observatory used in areas of astronomy ranging from star formation to galaxy evolution and the properties of planetary systems from the first galaxies in the universe. Designed to revolutionize

However, because JWST is a project of unprecedented complexity, the mission has struggled to launch. What was initially proposed as a $1 billion observatory launch in 2007 became a $10 billion project launched in 2021.

The JWST does not orbit the Earth itself, but rather occurs at the point where the gravitational pull of the Earth and the Sun is equal to each other, called the Lagrange point. Specifically, the observatory is located at Earth-Sun L2, the Earth’s farthest from the Sun.

James Webb Space Telescope vs Hubble Space Telescope

The Hubble Telescope was launched on 24 April 1990. This type of space telescope was first conceived in the 1940s. This plan was under constant work and research for many years before the Hubble Space Telescope was launched on April 24, 1990. Initially it was called the Large Space Telescope.

What are the latest updates from JWST?

JWST has gone through several important phases to reach where it is now. After traveling to its final destination, it deployed its instruments, cooled, aligned its telescope and even took several photographs.

Now, the telescope has made all its adjustments and is perfectly focused and aligned. The next step is to properly calibrate the equipment. It simply means making sure they are distributing their data in a way that is understandable.

James Webb space telescope images

Recently NASA has released the first pictures taken by the James Webb Space Telescope. The world was eagerly waiting for the image taken from the James Webb Telescope, they revealed one of the first images taken by the James Webb Space Telescope! And the results are already looking spectacular! This is one of the deepest and clearest photos of the universe ever taken. The brightest stars stand out proudly in the image, characterized by their six long and sharp diffraction spikes (an effect due to Webb’s mirror configuration), while the galaxies beyond them appear to be very striking in their cosmic form.

First pictures from the James Webb Space Telescope (jwst first images)
This image cannot be studied to determine the age of these space structures because color filters were not used in the imaging process, but it still provides a remarkably stunning view of the universe.

According to NASA, this image was somewhat unplanned, because they did not think that the telescope would be able to capture it. The space agency did not think there would be enough communication bandwidth to transmit imagery between Earth and L2 - L2, a point in space 1.5 million kilometers away and home to the Webb telescope, as it provided a clear view of deep space. provides. These may prove to be scientifically useful in the future.
