NASA's Webb telescope reveals deepest image of early universe

The James Webb Space Telescope, the most powerful to be placed in orbit, has revealed the clearest image to date of the early universe, going back 13 billion years.

Known as Webb's First Deep Field, it shows the galaxy cluster SMACS 0723, which acts as a gravitational lens, bending light from more distant galaxies behind it towards the observatory, in a cosmic magnification effect.
