The James Webb Space Telescope (JWST) 🔭 was launched late last year Dec 25, 2021, a project led by the United States of America 🇺🇸 through NASA and 13 other countries namely – Austria, Belgium, Canada, Denmark, France, Germany, Ireland, Italy, the Netherlands, Spain, Sweden, Switzerland, and the United Kingdom.

The $10 billion James Webb Space Telescope – NASA’s largest and most powerful space science telescope – will probe the cosmos to uncover the history of the universe from the Big Bang to alien planet formation and beyond.

This new Telescope’s capability of seeing through infrared light (electromagnetic radiation with wavelengths longer than those of visible light. It is therefore invisible to the human eye).

It will have four major assignments – (i) see into the past (ii) probe how galaxies formed in the past (iii) probe into the birth of stars and protoplanetary systems (iv) birth of planets including origins of life.

The distance of objects seen are about 5 billion light years away – distance back into the history of the universe. (Far back in time)

The James Webb Space Telescope will help test the BIG BANG THEORY. The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began – American Museum of Natural History (AMNH).

“This high-resolution infrared images from the Webb Space Telescope will help researchers identify where stars are forming behind dust and study the earliest stages of star formation in this galaxy.”

Spectra also tell us an immense amount about galaxies, including very distant galaxies as they existed in the early universe. In the graphs above, we’ve plotted the light gathered from three spiral galaxies /NASA/
Illustration showing what exoplanet 55 Cancri e could look like, based on current understanding of the planet. 55 Cancri e is a rocky planet with a diameter almost twice that of Earth orbiting just 0.015 astronomical units from its Sun-like star. Because of its tight orbit, the planet is extremely hot, with dayside temperatures reaching 4,400 degrees Fahrenheit (about 2,400 degrees Celsius) /NASA/

We are in for a treat as the most powerful telescope surprises us, challenges our beliefs, thoughts and outlook. For more images and information, visit NASA website.
