Galaxy Cluster Abell 2218, artist’s impression
This is an artist’s impression of a famous Hubble image of a cluster of galaxies about 2 billion light years away. Acting as a powerful gravitational lens, it magnifies and distorts all galaxies lying behind the cluster core into long arcs. The galaxies so affected are stretched along the clusters and some of them are multiple imaged.
In this artwork, one can see the most prominent arc, an orange/red arc at centre right. However artistic licence was used in showing larger blue lines, to emphasize the phenomenon. This work contains groups of individual lights which slowly emerge and fade alternately.
