How James Webb Telescope Works?

The James Webb Space Telescope is the most powerful space telescope ever built by space scientists. Canada has also contributed a scientific instrument and a guidance sensor to the massive observatory, which may bring breakthrough discoveries in the mysterious astronomy. Let’s see How James Webb Telescope Works?

Launch: December 25, 2021 । Status: Operational at Lagrange 2

Mission of The James Webb Space Telescope:

The James Webb Space Telescopee has designed to:
1. observe distant objects into the universe for the first time
2. search for the origin of the universe after the great Big Bang
3. understand how planets, stars and galaxies were made and evolve over time
4. explore the farthest worlds and deeply study our solar system
5. Search for the potential for life on other planets around billion of stars

How James Webb Telescope Works?

Webb uses infrared light that cannot be visible by the human eye, to study every phase in cosmic history from the beginning.

The telescope’s four scientific instruments are specifically designed to capture infrared light, and are able to travel through cosmic dust to study colder or very distant objects in the universe.

There are many kinds of light everywhere around us. but we can see only the rainbow of light. And several other types of Light – like X-rays, infrared, microwaves, radio waves – that are not visible to the human eye.

Certain types of objects such as exoplanets and very distant galaxies shine most brightly in infrared light. A variety of instruments have been built to capture does types of non-visible infrared light and help study different celestial phenomena like exoplanets, red dwarf stars , black holes another celestial bodies.

About the telescope:

Webb is the result of over 20 years of planning and development. Several elements make the space observatory unique and help ensure it will meet its objectives:

Golden mirror:

Webb’s primary mirror is 6.5 metres wide, making Webb the largest space-based telescope ever built. The mirror is made up of 18 hexagonal gold-coated beryllium segments that can be adjusted individually according to the need.

Sunshield:

To protect itself from the Sun’s heat, Webb has a tennis court-sized sunshield as a protection. One of Webb’s instruments also has a refrigeration system to keep it cool inside, because the heat from the Sun and Webb’s own instruments would otherwise interfere with the telescope’s observations.

Deployment:

Webb is so large that it needed to be folded up like a piece of origami to fit into the Ariane 5 rocket that launched it into space during 2021. It took Webb about two weeks to fully unfold from the fold state, and two more weeks to travel to its final destination where it planned to set.

Instruments:

The Webb Telescope has scientific instruments as NIRISS, NIRCam (NASA), NIRSpec (European Space Agency [ESA]) and MIRI (NASA/ESA).

High-frequency radio transmitter: Large radio antennas spread out around the globe to receive The James Webb Space Telescope’s transmitter signals and forward them to the Webb Science and Operation Center at the Space Telescope Science Institute in Baltimore, USA.

James Webb Space Telescope discovered a new black hole

James Webb Space Telescope and Hubble had launched to view the distant Galaxies, black holes, stars, nebula etc. interstellar objects to have multiple research on the birth of our universe. Recently, it has done some great work by discovering new planets nebula’s galaxies and some black holes those are millions of light years away.

NASA James Webb Space Telescope recently detected the brightest light ever:

Recently, A pulse of intense radiation swept through our solar system that astronomers nicknamed the BOAT: the brightest of all time. Several NASA missions have followed up to study this gamma-ray burst, which scientists believe was caused by the birth of a black hole that formed when the core of a massive star collapsed under its own weight.

As that new black hole quickly consumes surrounding matter , it blasts out jets of material in opposite directions that contain particles accelerated to almost the speed of light, emitting X-rays and gamma rays as they stream into space. That’s why scientists believe that it could be a newborn black hole.

How long will it take to see supernova explosion?

After such an event, astronomers expected to detect a supernova in the weeks following, but haven’t found it so far although the burst did occur in a part of the sky just a few degrees above the plane of our Milky Way Galaxy, where thick dust cam dim incoming light.

Astronomers have used Hubble and NASA’s James Webb Space Telescope to try and detect this supernova since the telescopes’ infrared capabilities can peer through cosmic dust and can see beyond. It’s proven elusive so far, but future observations are planned over the next few months- said the research team of NASA.

This Hubble image combines observations taken one and two months after the eruption, and shows the infrared afterglow of the gamma-ray burst, designated by the small, superimposed circle. Given its brightness, the burst’s afterglow may remain detectable by telescopes for years to come. And also James Webb Telescope & hubble telescope could help better.
