The image is a detailed and colourful visualisation of the cosmic web, which shows the large-scale structure of the Universe. The left side of the image is filled with blue and purple colours and is a bit wispier/darker. The right side has bright orange and yellow colours and is much bolder/brighter. In the centre, there is a bright green-blue area where these two sides meet, forming a complex network of filaments that connect various clusters of galaxies. The text ‘ILLUSTRIS’ appears in small font at the bottom right corner.
