NASA’s James Webb Space Telescope is the most sophisticated scientific observatory ever made by humankind. NASA, in collaboration with European Space Agency (ESA) and the Canadian Space Agency (CSA), launched and is operating this telescope. Launched in December 2021, the telescope was put in orbit in January 2022. The telescope is named after the administrator of NASA, James E. Webb who was the administrator during the Gemini and the Apollo programs. Previously, NASA had the deepest observations into the universe’s distant past using the Hubble Space Telescope which is powerful enough to observe and capture the night sky up to billions of light-years away called the Hubble Deep Fields. JWST is the successor of the Hubble Space Telescope with much sophistication and powerful infrared resolution technology.

On 11th July 2022, President Joe Biden released the first image from the James Web Space Telescope. The image peeks into thousands of galaxies in the galaxy cluster SMACS 0723 revealing the distant past for us making it one of the sharpest images of the earliest universe.

The distortions seen in the image are due to a phenomenon known as gravitational lensing where the galaxy clusters…
