US President Joe Biden has unveiled the first picture taken by Nasa's James Webb telescope (JWST), the most detailed glimpse of the universe ever seen.
Known as 'Webb’s First Deep Field', the picture showcases a galaxy cluster called SMACS 0723 as it appeared 4.6 billion years ago. It is the first of several pictures scheduled to be released over the next few days.
When unveiling the picture, Biden called the moment “historic” and said it provided “a new window into the history of our universe”.
The image was taken by Webb’s Near-Infrared Camera (NIRCam) and is a composite made from images at different wavelengths, some of them invisible to the human eye. The image is the farthest humanity has ever seen, in terms of both time and distance, with part of Webb's First Deep Field showing light from soon after the Big Bang.
