Why is the James Webb telescope hexagonal?
Focusing a giant hexagon The space telescope’s signature honeycomb mirror segments are shaped as such because the pieces can fit together in a way that makes it possible for the primary mirror, made up of all of the pieces, to be a roughly circular shape, according to a NASA statement.
Why does the James Webb telescope mirror have a honeycomb configuration?
Their honeycomb like arrangement allows for Webb to have the largest possible reflective surface area to make observations, with the least amount of dead space in between each. The overall power and effectiveness of a telescope is primarily determined by how big a mirror it has.
Why are the mirrors of the James Webb Space Telescope covered with gold?
The James Webb Space Telescope has been plated with gold due to elements properties like a high reflection of infrared light and extreme unreactivity. The James Webb Space Telescope is at the end stage of its launch preparations and is just days away from unraveling new secrets about our universe.
How many mirrors does the James Webb Telescope have?
18
The James Webb Space Telescope’s 18 special lightweight beryllium mirrors have to make 14 stops to 11 different places around the U.S. to complete their manufacturing. The 18 mirror segments will form the Webb telescope’s huge primary mirror.
What are the JWST mirrors made of?
beryllium
Each of the telescope’s mirrors are covered in a microscopically thin layer of gold, which optimises them for reflecting infrared light – the primary wavelength of light this telescope will observe. To ensure the mirrors are both strong and light, the team made the mirrors out of beryllium.
What are the mission objectives of the JWST?
JWST. Objectives: JWST’s primary aim is to shed light on our cosmic origins: it will observe the Universe’s first galaxies, reveal the birth of stars and planets, and look for exoplanets with the potential for life.
Why do space telescopes have mirrors?
Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. The first telescopes focused light by using pieces of curved, clear glass, called lenses. Because mirrors are lighter, and they are easier than lenses to make perfectly smooth.
What is the primary mission of the JWST?
JWST’s primary aim is to shed light on our cosmic origins: it will observe the Universe’s first galaxies, reveal the birth of stars and planets, and look for exoplanets with the potential for life.

Why is James Webb gold plated?
Gold-coated mirrors Each of the mirrors is coated with about 0.12 ounce of gold to optimize it for the reflection of infrared light. “We faced many technical challenges on the Webb mirror coating program,” said Ian Stevenson, director of coating at QCI.
Where is the Fermi telescope located?
Fermi, which was called the Gamma-ray Large Area Space Telescope (GLAST) until it reached its operational orbit, launched on June 11, 2008, from Cape Canaveral Air Force Station aboard a Delta II Heavy rocket. It was placed into a circular orbit around Earth with an altitude of about 350 miles (560 kilometers).
