James Webb telescope:

The James Webb Space Telescope (JWST) is a large, space-based observatory designed to study a wide range of astronomical objects and phenomena. This telescope is being developed as a collaboration between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). The JWST is designed to be successor to the Hubble Space Telescope and is expected to be one of the most powerful telescopes ever built.

Launch date:

The launch date of the James Webb Space Telescope (JWST) is currently planned for March 30, 2023.

Cost os JWST:

The James Webb Space Telescope (JWST) has a estimated cost of approximately $10 billion USD.

Search for habitable worlds:

The JWST is equipped with a suite of state-of-the-art scientific instruments, including a near-infrared camera, a near-infrared spectrograph, and a near-infrared imager and slitless spectrograph. These instruments will allow the JWST to observe the universe in unprecedented detail, from the formation of the first galaxies and stars to the evolution of planetary systems and the search for habitable worlds.

Main Goals of JWST:

One of the main goals of the JWST is to study the formation and evolution of galaxies, stars, and planetary systems. This will be done by observing the light emitted by these objects and analyzing their properties, such as age, temperature, and chemical composition.

The James Webb telescope will also be able to study the formation of the first galaxies, which formed in the early universe, and will be able to observe the light from these galaxies to learn about their properties and evolution.

Another important goal of the JWST is to study the evolution of planetary systems and search for habitable worlds.

The JWST will be able to directly observe exoplanets and study their atmospheres, providing insights into their potential habitability.

Additionally, the JWST will be able to study the evolution of protoplanetary disks, which are the birthplace of planetary systems, and the formation of planetary systems around other stars.

The james webb telescope will also be able to study the universe in a new way by observing the light from the first stars and galaxies that formed after the Big Bang. This will allow scientists to learn about the properties of the universe in its early stages, such as its composition and temperature.

Additionally, the JWST will be able to observe the light from the earliest supernovae and study the chemical elements that were produced in these explosive events.

Features of James Webb telescope:

Infrared capabilities: James Webb telescope is equipped with sensitive infrared detectors, which will allow it to see through dust clouds and observe the formation of stars and galaxies.
Large sunshield: JWST has a large sunshield, which helps to keep the telescope cool and allows it to detect faint infrared signals.
High resolution imaging: JWST has a large mirror (6.5 meters in diameter) that will allow it to take high resolution images of distant objects.
Wide field of view: JWST has a large field of view, which will allow it to observe large areas of the sky at once.
Sun-Earth L2 orbit: JWST will be positioned at a special point in space called the second Lagrange point (L2), which is located about 1.5 million kilometers from Earth in the direction away from the Sun. This will provide a stable environment for observing the universe.
Collaboration with other telescopes: JWST will work in conjunction with other telescopes, both on the ground and in space, to provide a more complete picture of the universe.

Sunsheild on JWST:

One of the key technological innovations of the James Webb telescope is its sunshield, which is designed to protect the telescope from the heat and light of the Sun.

Kapton:

The sunshield consists of five layers of a special material called Kapton, which is designed to reflect the heat of the Sun away from the telescope. The sunshield also provides a stable thermal environment for the telescope, ensuring that it operates at the correct temperature for scientific observations.

Lagrange point:

The JWST will be launched into a special orbit known as a Lagrange point, where it will be able to observe the universe without interference from the light and heat of the Earth and the Moon. This orbit, known as L2, is located approximately 1.5 million kilometers from the Earth and provides a stable environment for the JWST to operate.

Comparison to hubble:

The James Webb Space Telescope (JWST) and the Hubble Space Telescope (HST) are both space-based observatories designed to study the universe. However, there are some key differences between the two:

Size: JWST is larger than Hubble, with a mirror that is 6.5 meters in diameter compared to Hubble's 2.4 meters.

Location: JWST will be positioned at the second Lagrange point (L2),which is about 1.5 million km from Earth, whereas Hubble is in low Earth orbit.

Purpose: JWST is designed to primarily observe infrared light, making it well-suited for studying the formation and evolution of galaxies, stars, and planetary systems. In comparison, Hubble is a more general-purpose observatory that observes across the electromagnetic spectrum, from ultraviolet to near-infrared light.

Capabilities: JWST has more advanced optics and detectors, which allow it to see deeper into the universe and gather more detailed observations. Additionally, its sunshield will protect it from the sun's heat, allowing it to make very sensitive observations.

Overall, while both telescopes have unique capabilities, JWST is expected to complement and build upon the legacy of Hubble, providing new insights into the universe and our place within it.

Scientific achievements:

Despite the many scientific achievements that are expected from the JWST, the development of the telescope has been marked by significant challenges and delays. The initial launch date of the JWST was delayed several times due to technical difficulties, and the overall cost of the project has increased significantly. However, despite these challenges, the JWST is widely regarded as a critical mission for the study of the universe and is expected to provide a wealth of new scientific insights and discoveries.

Observatory:

The James Webb Space Telescope (JWST) is set to be launched and operated from space, therefore it does not have a specific observatory location on the ground. However, the JWST is a collaboration between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA) and will be managed from several ground-based facilities, including the Space Telescope Science Institute in Baltimore, Maryland, which will be responsible for the scientific operation of the telescope.
