The James Webb Space Telescope is the next chapter in alien-based telescope astronomy. Webb's mission builds on the Hubble Space Telescope's legacy of powerful imaging capabilities and is inspired by the Spitzer Space Telescope's imaging capabilities. The parameter in the telescope's construction is the light's ability to detect the mid-infrared, which is beyond the visible spectrum. As infrared light passes through dense clouds of gas that block visible light, Webb will reveal previously hidden regions of the universe. These days, space enthusiasts and science lovers eagerly await the launch of the James Webb telescope. Three days later, James Webb launches on December 25. The launch site is French Guiana.

We can list the working areas of the telescope as follows.

  • early galaxies
  • Formation of planets
  • Brown Dwarfs (One Step of Star Evolution)
  • Much more

Largest Telescope Sent into Space

Webb's innovative design overcomes two main challenges for an infrared telescope. It needs to have a large mirror to best capture enough light. It needs to be kept cool to prevent unwanted infrared sources from interfering with the observed light. Webb's tennis court-sized awnings shield it from stray heat and light from the Sun, while its wide-section mirror (6,5 sections covering 21.3 meters (18 feet) at its widest point) allows it to effectively capture infrared light.

The spectacular skyscape this telescope will provide and the deeper understanding of our universe and its origin are a valuable destination for this complex and challenging journey. (Next Generation Space Telescope Workshop Report, 1989)

Launching such a large mirror into space was another big challenge. Creative engineering work was supposed to answer that?

The origami-inspired folding telescope is designed to open after the telescope leaves the launch vehicle, with both its sunshade and mirrors. This video It simulates Webb's journey to its orbital position beyond the Moon, about 1 million miles from Earth.

We would like to share with you the statement of NASA Administrator James Webb in 1962.

…scientific work feeds technology and engineers start building better spacecraft. This gives you better instruments and a chance to go out to learn more.

Webb's actual scientific observations are made by four instruments, each specially designed to study different aspects of infrared light.

If we list them;

  • Near Infrared Camera (NIRCam);
  • Near Infrared Spectrograph (NIRSpec);
  • A Mid-Infrared Instrument (MIRI) with Camera and Spectrograph
  • Near Infrared Image and Slitless Spectrograph (NIRISS)

These tools include new technologies such as the microshutter array developed for Webb to increase the telescope's scientific capability and efficient operations throughout its mission.

Efficiency is crucial to James Webb's usefulness. While Webb is in operation, many more astronomers have been enabled to take advantage of it.

Using its best possible scientific capacity will also help astronomers investigate some of our most fundamental questions. How did we get here? How was the universe formed?

There's also a side to Webb's groundbreaking engineering. It will be possible to use many systems developed for the telescope on a world scale.
