A technical and aesthetic wonder

Düsseldorf, 15 July 2022: This week, NASA released five images of the James Webb Space Telescope for the first time. On Monday evening, US President Joe Biden, along with Vice President Kamala Harris, who is the chair of the National Space Council, unveiled the first 5 images of the James Webb Space Telescope. On Tuesday, NASA released another 4 images. 


The 6.5-metre James Webb reflecting telescope is now 1.5 million kilometres from Earth.


These images show some of the most detailed views of the beginnings of our universe ever seen. The new Webb images could be viewed on several screens in Times Square in New York City and Piccadilly Circus in London from 5:30pm EDT and 10:30pm GMT respectively.


The colour images in high resolution are available at:

NASA Administrator Bill Nelson said here. "These images, including the deepest infrared image of our Universe ever taken, show us how Webb will help find answers to questions we don't even know yet; questions that will help us better understand our Universe and humanity's place in it. (...) We are turning dreams into reality for the benefit of humanity. I can't wait to see the discoveries we make - the team has only just begun!"

SMACS 0723: 

James Webb has provided the deepest and sharpest infrared image yet of the distant universe. For a person standing on Earth looking up, the field of view of this new image, which is composed of several exposures, each lasting about two hours, is about the size of a grain of sand held at arm's length. 


Because light takes a long time to travel this far, you don't see the galaxies as they look today, but as they looked billions of years ago. The blue galaxies are more mature galaxies that contain many stars and little dust. The reddish galaxies contain more dust from which stars are still forming.

Carina Nebula: Birthplace of new stars

The Carina Nebula is 7600 light years from Earth, and is described as the stellar nursery of the cosmos. The formations, which look like cliffs, are peaks of dust and gas, some of which are light years high. The Hubble Space Telescope has shown the Carina Nebula before, but never in the rich detail that Webb has provided. Looking at this star-forming "Cosmic Cliffs" region in the Carina Nebula, Webb can see newly forming stars and examine the gas and dust from which they were formed.

Stephan's Quintet: Galaxy Crash

Webb captured the best image ever taken of Stephan's Quintet. It is a group of galaxies in the constellation Pegasus, first sighted by astronomers in 1877. James Webb broke through the dust mantle surrounding the centre of a galaxy to detect the velocity and composition of the gas near the supermassive black hole.

Southern Ring Nebula: Dying Stars

Webb captured an image of this pair of older stars orbiting each other about 2 500 light years from Earth. At the end of their lives, the stars eject gas and dust that form the nebulae or clouds that surround them.... The brighter of the two stars is younger than the other and has not yet ejected as much material. As the stars orbit each other, they set the gas nebula in motion and give it its characteristic shape.

The James Webb Space Telescope was launched on 25 December 2021 on an Ariane 5 rocket from the European Spaceport in French Guiana, South America. Its development by NASA, ESA and CSA took 25 years. The James Webb Telescope was built to capture the moment our universe came into being. The researchers want to explore our early universe as well as exoplanets and trace star formation.


In a complex unfolding sequence in space, the James Webb Space Telescope was commissioned with its mirrors aligned and its instruments calibrated to the space environment.


The James Webb Space Telescope is the world's most significant observatory for space exploration. Webb will solve mysteries in our solar system, peer to distant worlds around other stars, and explore the mysterious structures and origins of our universe and our place in it.
