About this image


Frame from of a computer simulation of a large portion of the observable Universe. The image contains thousands of galaxies, each containing clouds of stars here coloured pink. These are the structures that are normally visible to astronomers. Between the galaxies are immense streams of cooler gas, coloured according to temperature from blue (300 degrees) through green and yellow to red (6 million degrees). The distribution of matter through the Universe is governed by the interplay of these cosmic streamers of relatively cool gas that is not visible to astronomers.
