3.
When did the construction of the James Webb Space Telescope begin?
Correct Answer
A. 2002
Explanation
The construction of the James Webb Space Telescope (JWST) began in earnest in 2002. It has been a long and complex process involving the assembly of various components, testing, and integration of scientific instruments and systems. The project faced several challenges and delays during its development, but it represents a significant milestone in the field of space exploration and astronomy. The JWST will further our understanding of the universe in the near future.
4.
What is the primary mission of the James Webb Space Telescope?
Correct Answer
A. Studying exoplanets
Explanation
The primary mission of the James Webb Space Telescope (JWST) is studying exoplanets and various other astronomical phenomena. JWST is designed to observe the universe in the infrared spectrum and will contribute significantly to our understanding of exoplanets, their atmospheres, and their potential habitability. It will also study the early universe, galaxies, stars, and other celestial objects, making it a powerful tool for various aspects of astronomy and astrophysics.
5.
Which of the following is a major component of the James Webb Space Telescope?
Correct Answer
A. Primary Mirror
Explanation
A major component of the James Webb Space Telescope (JWST) is the Primary Mirror. The primary mirror is a crucial part of the telescope, as it collects and reflects light from distant celestial objects into the telescope's instruments, allowing for detailed observations in the infrared spectrum. It is a large segmented mirror that plays a key role in JWST's ability to capture high-resolution images and data from the universe.
6.
What is the diameter of the Primary Mirror of the James Webb Space Telescope?
Correct Answer
B. 6.5 meters
Explanation
Webb's primary mirror is 6.5 meters (21 feet 4 inches) across; a mirror this large has never before been launched into space.
7.
What is the main objective of deploying the James Webb Space Telescope?
Correct Answer
D. To find the first galaxies that formed in the early universe and to see stars forming planetary systems.
Explanation
The primary goal of the James Webb Space Telescope (JWST) is to explore the universe in ways beyond the capabilities of the Hubble Space Telescope. It aims to observe the most distant events and objects in the universe, such as the formation of the first galaxies, and to study the atmospheres of potentially habitable exoplanets and the process of star and planetary system formation. This deeper look into the cosmos will help scientists understand the origins of the universe and the likelihood of life on other worlds.
8.
What part of the electromagnetic spectrum does the James Webb Space Telescope primarily observe?
Correct Answer
D. Infrared light
Explanation
The James Webb Space Telescope (JWST) primarily observes infrared light. It is designed to study celestial objects and phenomena in the infrared portion of the electromagnetic spectrum. This allows JWST to observe distant galaxies, stars, and planetary systems, as well as study the formation of stars and planetary systems, in ways that are not possible with visible light or other parts of the spectrum.
9.
What year did the James Webb Space Telescope launch?
Correct Answer
B. 2021
Explanation
On December 25, 2021, NASA's James Webb Space Telescope, the successor to the renowned Hubble telescope, was launched with the mission of exploring the universe's distant past, studying the earliest stars, and peering deeper into cosmic history than ever before.
10.
What is the intended duration of the James Webb Space Telescope's primary mission?
Correct Answer
B. 10 years
Explanation
The James Webb Space Telescope (JWST) is designed for a primary mission duration of 10 years. This timeframe was selected based on the telescope's expected operational capabilities, fuel reserves for its propulsion system, and the science goals it aims to achieve. During this 10-year primary mission, the JWST will conduct a wide range of observations and scientific investigations, including studying the formation of stars and galaxies, exploring the atmospheres of exoplanets, and investigating the origins of the universe.
