Webb telescope

James Webb Telescope goals:

  • The James Webb Telescope will allow scientists to study galaxy, star, and planet formation.

How The James Webb Telescope Works 

The James Webb Telescope is 21 feet, 4 inches wide in diameter with 18 hexagonal shapes made from gold-plated beryllium, versus the Hubble space telescopes mirrors are only 7 feet, 10.5 inches. 

Both of the Hubble mirrors are primarily-made from thin layers of aluminum and magnesium fluoride. 

The James Webb's diameter of 21 feet, 4 inches makes it the largest space telescope in history that will go to space. 

The Space Telescope will be roughly 930,000 miles away from Earth, with a ten year supply of fuel. The James Webb Space Telescope has estimated to be 8.8 billion US dollars. 

The JWST is far-away from Earth because it needs to stay frigid. The mirror temperature averages -388 degrees Fahrenheit. The Telescope needs to remain cold to observe red-shifted light ( light that-is moving away from Earth).    

The James Webb Telescope can take a photo

The quality of the image is dependent on sharpness and the number of pixels in the camera. However, when the JWST shoots a photo, it will be infrared. The infrared image will then be translated by a computer and be a visible photo.

Who was James Webb

The space telescope is named after James E. Webb; Webb was born in 1906 and died in 1992. James E. Webb served as the second appointed administrator of NASA from 1961 to 1968. During his time at NASA, he lead multiple Apollo missions. Apollo was a series of lunar missions that lead to the first humans on the Moon.

When Will James Webb Launch

The James Webb Space Telescope will launch in 2021 from French Guiana. The space telescope will launch with Ariane 5 ECA rocket. Arianespace created the Ariane 5 rocket-which is a European aerospace company. Webb was-designed to live at least 5 1/2 years; 10 years optimally.
